  • 摘要：The non-isothermal kinetics for mesophase transformation of Baogang-I coal tar pitch (I-CTP), soft pitch consisted of I-CTP and 18% phenanthrene residue oil (PRO) or I-CTP and 30% PRO have been studied in a thermal conversion unit. Kinetic parameters were calculated by using an integral method. Results showed that the process of mesophase pitch transformation could be described in first order reaction. The activation energy of I-CTP is 175.36kJ/ mol. But adding 30% PRO, which improved the reactivity of I-CTP with activation energy is 138.07kJ/mol, is not beneficial to mesophase transformation.
  • 摘要：The emission of sulfur dioxide in flue gases is an important problem in industry involving combustion of coal. The wet scrubbing process using lime/limestone slurry as the scrubbing medium is currently the dominant technology for the flue gas desulfurization. Due to the presence of numerous ionic and neutral species in the slurry, the chemical reactions involved in the slurry upon absorption of sulfur dioxide are complex. In this paper, a method of measuring the sulfur dioxide absorption in multi-component suspensions was developed and the characteristics of sulfur dioxide absorption were investigated. The results show that different additives chosed in the experiment can improve the ability of SO2 absorption. As to the same additive, the improvement effect is differ with different concentration. For the magnesium hydroxide additive, its optimum concentration is 1×10-4 mol/L. Experiment results suggested that dissolved sulfur dioxide reacts mainly with the magnesium sulfite ion pair which is responsible for the increased absorption rate of SO2. However, when CO2-3 or SO24- anions are present in the solution, the catalytic effect of magnesium hydroxide precipitate on sulfur dioxide absorption reduces. According to the experiments, absorbents with better performance can be optimized to be applied in semi-dry or wet FGD process to raise SO2 removal efficiency.

  • 摘要：运用高性能静态二次离子质谱从中国贵州(六枝)超高硫原煤有机相中观测到元素硫与铁的复合组成离子。由此，首次以确切的实验证据支持了过去关于煤中可能存在铁-硫复合结构的理论推测；同时本工作还表明，所采用的超高灵敏度和微区离子探针分析方法，适于今后进一步探索硫及其它有害元素在煤中的复杂化学赋存状态。%The complex of elemental sulfur binding with iron in organic phase of coal is primarily observed by a high performance static secondary ion mass spectrometry(TOF SIMS)when a super-high sulfur coal, located at Guiding of southwestem China, is used as the test sample. This observation, as the first evidence, experimentally supports the theo ry of possible occurrence of iron-polysulfur complex in coal suggested recently. Meanwhile, the micro ion probe with high mass resolution and super-high sensitivity, the TOF SIMS used here, is demonstrated to be available for further approaching some complicatedly chemical states of sulfur or other harmful elements existing in coal.
  • 摘要：Pd and/or Cu - La2O3/SiO2 catalysts were prepared by Pd and/or Cu supported on La2O3/SiO2 with im pregnation. The capacities of catalysts reduction and the performance of reaction were studied by H2 - TPR and hydro genation of CO2. The results of H2 - TPR indicate that increasing the content of CuO is advantageous to the reduction of high dispersing CuO, but adding La2O3 hinder the reduction of high dispersing CuO. It was found that Pd- Cu alloy formed while Pd, Cu impregnated on La2O3/SiO2. The results of hydrogenation of CO2 indicate that CO2 conversion is promoted by adding La2O3 increasing the content of CuO. The thermal stablity of methanol formation was improved by adding La2O3. Aldehyde can be obtained when Pd- Cu were used as active components, and the production of methanol was related to the content of Pd loaded on the support.
  • 摘要：用四种不同煤阶的煤，经过HCl/HF脱灰处理制得四种脱灰煤，950℃下热解制得原煤半焦和脱灰煤半焦。在石英固定床反应器上于常压条件下400℃～950℃的温度范围内考察比较了原煤半焦和脱灰煤半焦还原NO的反应性，研究了煤中矿物质对NO-半焦还原反应的机理和反应动力学的影响。结果发现，煤中的矿物质一般对NO-半焦反应具有一定的催化作用，催化作用的大小与矿物质的含量和组成有关；钠、铁和钙等是矿物质中活性分，对NO-半焦反应具有催化作用；半焦还原NO的反应存在明显的双温区现象，低温反应机理与高温反应机理不同，活化能有明显差异。%The NO-char reduction in the presence and absence of mineral matter was studied. Four Chinese coals with different ranks from lignite to anthracite were demineralized with HC1/HF and the chars were prepared by devolatilizing the deashed coals and their original coals in a quartz fluidized-bed reactor. NO reduction by the resulting chars was conducted in a quartz fixed bed at atmospheric pressure. The results showed that alkali metal Na and alkali earth metal Ca catalyzed the NO-char reaction significantly. However, the catalytic effect of Fe in the mineral matter was weak due to the inhibition of inert composition. Kinetics data of NO-reaction reduction by coal chars in the presence and absence of mineral matter were obtained. Two temperature regimes were found in the NO-char reaction, which suggested the mechanism shift in the transition temperature.

  • 摘要：采用以质谱为检测器的程序升温和瞬变实验技术研究了0.1MPa和0.7MPa条件下CH4部分氧化制合成气反应。结果表明，与0.1 MPa条件下一样，在700℃、0.7MPa下CH4可以在金属镍活性中心上迅速分解生成H2和表面NixC，但CH4不能在NiO上分解，也不能被其氧化。CH4的分解，作为在Ni/Al2O3催化剂上进行部分氧化制合成气反应的第一步，是一个体积增大的反应，因而加压会抑制反应的进行。正是由于在加压条件下CH4的分解受到抑制，才使得在0.7MPa下CH4的转化率明显低于0.1 MPa。此外，加压有助于维持催化剂表面处于还原状态，这有利于反应高转化率、高选择性地进行。%Partial oxidation of CH4 to syngas was investigated under 0.1 MPa and 0.7MPa using temperature-programmed and transient experimental technique with MS as the detector. CH4 can decompose over metallic Ni sites rapidly and can not over NiO under 0.7 MPa, which is the same as that under 0.1 MPa. The decomposition of CH4 over the Ni/A12O3 catalyst, the first step of partial oxidation of CH4 to syngas, is a volume increase reaction and is restrained under 0.7 MPa. The conversion of CH4 is affected by pressure markedly. Higher pressure is favorable for keeping the catalyst in its reduced state that is necessary for the reaction to proceed with high conversion and selectivity.
  • 摘要：以5 W/％稀HCl溶液对各类城市生活垃圾衍生燃料(RDF)及其组分进行处理，考察在不同温度下快速热rn 解生成半焦的动力学参数变化，并对半焦的比表面积和孔体积的变化和分形维数进行分析研究。试验结果发现酸rn 洗后RDF热解速率提高，活化能降低。酸洗后半焦的比表面积和孔体积均有所减小，并随热解温度先升高而后下rn 降，在450℃附近出现极大值。对半焦的分形维数分析表明，酸洗后表面变得光滑，形成欧氏平面。%Refuse derived fuel (RDF) and its components were treated by 5% HC1 and the changes of kinetic parameters for rapid pyrolysis under different temperature were discussed. The changes of the specific surface area (SSA), pore volume (PV) and fractal dimension for residue were also investigated and analyzed in this paper. The experiment results show that the pyrolysis rate increases and activate energy decreases for RDF after acid treatment. SSA and PV of RDF vary with the reaction temperature during rapid pyrolysis. With increasing temperature, the SSA and PV of acid treated RDF residue rise in the beginning and down in the end. The maximum value appears near 450℃. Further more, the fractal feature of acid treated RDF residue is also discussed. The surface of residue seems smoother and form Euclidean plane after acid treatment.
  • 摘要：采用表面反应改性法制备了SnO2-SiO2(SnSiO)表面复合物载体，用等体积浸渍法制备了SnSiO担载的Cu-Ni双金属催化剂。借助BET、XRD、TPR、IR和微反等技术研究了SnSiO及其负载的Ni、Cu双金属催化剂的表面构造、化学吸附及CO2加氢反应性能。结果表明：SnSiO是SnO2单分子层价联于SiO2表面的复合氧化物，仍保持类似SiO2载体的孔结构和比表面；SnO2引入SiO2表面后可以有效地促进CuO、NiO的还原，还原后成为负载在SnSiO载体表面的Cu-Ni合金；CO2在负载型Cu-Ni合金表面Cu或表面Ni位上发生化学吸附，形成线式和剪式吸附态；CO2在催化剂上的加氢反应产物主要是CH3OH、CH4、CO和H2O，生成CH3OH的选择性与催化剂组成及反应条件密切相关。Cu-Ni催化剂，在0.5 MPa，170℃，H2/CO2(mol/mol)为3的条件下，CH3OH的选择性达到84.6％。%The surface complex oxide supports of SnO2-SiO2 (SnSiO) were prepared by modifying surface character. SnSiO supported Ni-Cu binary metal catalysts were prepared by the isometric impregnation method. The surface struc ture of SnSiO and Cu-Ni/SnSiO, the chemisorption properties and CO2 hydrogenation over Cu-Ni/SnSiO catalysts have been characterized by using the techniques of BET, XRD, IR and micro-reactor. Experimental results showed that SnSiO supports are bond-conjugated type surface complex oxides which have the same pore structure as SiO2 support. The presence of SnO2 on the surface of SiO2 can promote the reduction of CuO and NiO. CO2 can be adsorbed mainly on the Ni sites or on the Cu sites of Cu-Ni alloy to form linear and shearing adsorption. The main products of CO2 hydrogenation are CH3 OH, CH4, CO and H2 O. The selectivity of CH3 OH depends strongly on the catalyst components and reaction conditons. About 8 6.4 % selectivity of CH3 OH can be attained over Cu - Ni / SnSiO - 2 catalyst at 170 ℃, 0.5 MPa and H2/CO2 (mol/mol) = 3.
  • 摘要：分析了甲醇重整制氢反应可能的反应途径。分析结果表明体系中有2个独立反应，则至少应有2个动力学方程才能描述。利用平衡温距的概念，分析了WGS反应在甲醇水重整反应体系中的作用，根据在固定床反应器上的实验结果，证明变换反应不宜出现在动力学模型中。合理的动力学模型认为水蒸气重整反应和甲醇分解反应平行进行，CO和CO2同时生成。%Different routes of methanol-steam reforming over ZnO-Cr2O3 catalyst have been discussed. There are two independent reactions with five components and three elements in this process . Using the parameter defined as the difference between the real temperature and pseudo thermodynamic equilibrium temperature based on the value of PcoPH2o/Pco2 PH2 in the outflow, our calculations of experimental data showed that neither the water-gas shift reac tion nor its reverse reaction is proper to appear in the kinetic model. The reasonable model may be represented by parallel reaction model, taking SRM and DE as the independent reactions. Therefore the two components of CO and CO2 are produced simultaneously.
  • 摘要：@@1 蒙特卡罗方法简介rn 足球比赛开始前，裁判往往用掷硬币的方法决定双方进攻的方向。这种方法两方都能接受，因为正面朝上和朝下的机会是相同的，也就是说概率都是50％。现在，假如我们往地上掷一个密度不均匀、形状不规则的多面体，问某一个面朝地的概率是多少?恐怕没有人能知道。找到答案的方法其实很简单：把这个多面体一次又一次地往地上投，数出该面朝地的次数，然后再除以总的投掷次数。这种解rn决问题的方法实际上就是蒙特卡罗方法。
  • 摘要：用Fe2O3作催化剂，硫黄为助催化剂，脱晶蒽油为循环溶剂，在反应温度为450℃，初始氢压为10MPa，反应时间为60min.的实验条件下，在微型高压釜内对马家塔原料煤及其显微组分的加氢液化特征进行了系统研究。镜质组的液化反应性高于惰质组，在原料煤、镜质组和惰质组这三种实验原料中，原料煤的液化反应性是最高的。对总转化率和油收率而言，原料煤＞镜质组＞惰质组，对沥青烯产率而言，原料煤＞惰质组＞镜质组，水产率则是镜质组＞原料煤＞惰质组，气产率为惰质组＞镜质组＞原料煤。原料煤、镜质组和惰质组在加氢液化过程中所产生的气体在组成上也是有所差异的。各显微组分在加氢液化过程中可能存在着协同作用。%The hydroliquefacton characteristics of Majiata coal and its individual macerals were systematically investigated in a microautoclave at the following experimental conditions: reaction temperature of 450 ℃, initial H2 pressure of 10 MPa, residence time of 60min., decrystallized anthracene oil was used as a solvent, Fe2O3 plus sulfur as the catalyst. The hydroliquefaction reactivity of vitrinite is higher than that of inertinite, and the parent coal has the highest hydroliquefaction reactivity among these three feedstocks. The reactivity order for the total conversion and oil yield is: parent coal＞vitrinite＞inertinite, for asphaltene yield: parent coal＞inertinite＞vitrinite, for water yield: vitrinite＞parent coal＞inertinite, for gas yield: inertinite＞ vitrinite＞parent coal. The composition of gas from hydroliquefaction of the parent coal, vitrinite and inertinite is different. Synergism between the individual macerals during hydroliquefaction process exists.
  • 摘要：在常压、室温条件下利用电晕放电使二氧化碳通过冷等离子体反应分解为一氧化碳和氧气，由四极质谱在线定量分析产物组成。考察反应条件（电晕类型、能量密度、气体流量等）对反应转化率的影响，分析了该反应的能量效率。当放电功率为40?W、CO2流量为30 mL*min－1时，正电晕等离子体CO2分解反应的转化率为15.2%；CO2转化率随体系能量密度的增加而上升，随反应时间的增加而增大。当CO2流量为90 mL*min－1、正电晕放电功率为37.6?W时，反应体系的能量效率为5.89%；实验发现，正电晕放电时CO2的转化率高于负电晕的转化率。%The decomposition of CO2 through corona discharge of cold plasma reaction at ambient temperature and atmosphere was carried out. A quadrupole mass spectrometer was employed for online quantity analysis of the products of CO2 plasma decomposition reaction. The effects of reaction parameters on conversion and energy efficiency, such as different corona discharges (include positive corona discharge, negative corona discharge), energy density, flow rate of feed, etc. were investigated. For the flow rate of CO2 at 30?mL*min－1, discharge power at 40?W, the CO2 conversion was 15.2% in positive corona plasma reaction. The conversion increased with increasing energy density and decreased with increasing CO2 flow rate. For CO2 flow rate at 90?mL*min－1, power at 37.6?W, the energy efficiency was 5.89% in positive corona plasma reaction. The conversion of CO2 in positive corona discharge is higher than that in negative corona discharge.
  • 摘要：Two high-volatile subbituminous coals, DECS-6 of US and Yanzhou coal of China, were liquefied or co-liquefied with HDPE or PVC at 400?℃, 30?min under 7?MPa hydrogen. The results show that Yanzhou coal is easier to be liquefied or co-liquefied than DECS-6 coal under the experimental conditions used and the hexane-soluble oil from Yanzhou coal has more low boiling point fractions than that from DECS-6 coal. The aromatics in hexane soluble oils mainly consist of alkylbeneze, alkylnaphthalene, phenanthrene-,pyrene-, chrysene-, and benzopyrene- compounds, the polars mainly compose of compounds containing O， S and N etc.%在400 ℃、30 min、7 MPa冷氢压条件下两种煤液化结果表明，兖州煤比DECS-6(美国煤)煤更容易液化或共液化，这可能与兖州煤硫含量比较高有关，但DECS-6煤的油收率要高于兖州煤，表明EDCS-6煤容易裂解生成小分子化合物。同种煤液化油的沸点分布特征基本一致。UV(紫外光谱)特征表明，液化油中单环芳烃主要为烷基取代苯类化合物，二环芳烃组分主要是烷基取代萘类化合物，三环芳烃主要为渺位缩合的菲类化合物，四环芳烃主要为芘、屈艹类化合物，五环芳烃以苯并芘类化合物为主，而极性化合物可归属为含O、S、N的极性芳香化合物。
  • 摘要：A series of active cokes produced from Datong coal under the same conditions except activating time had been studied to elucidate the influence of the properties (BET surface area, micropore volume, pore size distribution, ratio of micropore area to total area, surface basicity) of the active coke on its adsorption ability for SO2 removal from flue gas. Furthermore, the desorption processes of the H2SO4-loaded active cokes was investigated. It is found that surface basicity in the form of meq benzoic acid/m2 micropore area can evaluate the desulfurization ability of active coke more rightly than in the form of meq benzoic acid/g active coke. Active coke adsorbing and oxidizing SO2 into H2SO4 is determined by surface basicity and micropore area. Moreover, micropore might be the main place for the storage of formed sulfuric acid. The results also further prove that micropore is the main place where SO2 is adsorbed and oxidized into sulfuric acid in the presence of oxygen and water vapor. The desorption process of H2SO4-loaded active coke is influenced not only by desorption temperature, but also by its physical and chemical properties. The H2SO4 adsorbed starts to react with carbon on the surface of active coke at about 210?℃ and reaches its maximum desorption rate at about 300 ℃.%讨论了四种煤制活性焦的性质对其脱除烟道气中SO2性能的影响。活性焦的表面碱性与微孔面积决定了其对烟道气中SO2的吸附与氧化。生成的硫酸主要贮存在活性焦的微孔内。活性焦内的硫酸在脱附温度为300?℃时达到最大脱附速率。
  • 摘要：Volatile matters of residue produced in coal hydrogenation were measured by using TGA. The effect of remaining hydrogenation catalysts on volatile matter measurement of residue was mainly concerned. It was found that the total volatile matter measured in temperature region of 110?℃～950?℃, which was used normally for coal, was always higher for the residue from catalytic hydrogenation than that from thermal reactions. By analyzing the shape of TG/DTG profiles, Fe1-xS and NaCl, which were active hydrogenation catalyst and by-product in the catalyst preparing process, would increase volatile matter (VM) yield due to their decomposition and evaporation, respectively. Therefore, the value from proximate analysis （110?℃ to 950?℃）was defined as total volatile matter (TVM), and the volatile matter yield from 110?℃ to 700?℃ was organic volatile matter (OVM). It was also found that OVM yields of both thermal and catalytic residual chars have the same linear relationship with H/C ratio, while their TVM yields do not. Clearly, the OVM mainly reflects the organic hydrocarbon materials in the chars and is not influenced by the enriched coal minerals, remained catalysts and by-products in residual chars.%用热重分析仪对兖州煤加氢液化残渣（THF不溶物）的工业分析进行了测定，重点考察了液化催化剂对其挥发分收率测定的影响。比较了相同液化条件下残渣的挥发分收率，发现催化液化残渣的总挥发分（GB法测定的挥发分含量）比热液化的高。通过对TG/DTG谱图的分析，确定了失重峰的归属，同时定义110?℃～700?℃间的挥发分V700为有机挥发分，该值与这两种残渣的H/C比遵循共同的线性关系，而与添加的液化催化剂无关，可作为表征液化残渣基本性质的参数之一。
  • 摘要：Using a Temperature-Programmed Reaction (TPR) technique, Gujiao coke loaded with alkali earth metal oxides were reacted with CO2. The results indicated that BaO, CaO, MgO have positive catalysis on coke solution loss reaction and the catalytic order is: BaO>CaO>MgO. Reactions with different oxides have different kinetic parameters. All kinetic parameters (initial reaction temperature, activation energy, pre-exponential) but reaction order are changed with the increase of catalyst content. There is a compensation effect between activation energy and the pre-exponential factor.
  • 摘要：通过高压连续微型反应装置，对镍-2,3,7,8,12,13,17,18-八乙基卟啉（Ni-OEP）在氮气和氢气中的反应行为进行了研究。实验结果表明，镍卟啉在氮气中的稳定性非常高，只有在高温（500 ℃左右）下才发生分解；而在氢气中，镍卟啉的稳定性比较低，即使不存在催化剂，反应条件较为温和（温度不超过400?℃，压力小于10?MPa），也有相当一部分镍卟啉发生分解，脱除所配合的金属；镍卟啉的临氢脱金属反应过程分为两步，第一步是卟啉分子中一个吡咯环上的外环双键加氢生成镍卟酚，第二步镍卟酚分解，金属脱除。%The reaction characteristics of nickel 2,3,7,8,12,13,17,18-octaethylporphyrin (Ni-OEP) in the presence of N2 and H2 have been investigated by using a high-pressure flow microreactor. In the presence of N2, Ni-OEP is very stable, and there is no reaction below 420?℃ and it only decomposes at high temperature (about 500?℃). But in the presence of H2, even in the absence of a catalyst and under mild reaction conditions, Ni-OEP can decompose and nickel is removed. The demetalation of Ni-OEP in the presence of H2 consists of two steps. The first step is hydrogenation of nickel porphyrin to nickel chlorin, and the second step is decomposition of nickel chlorin and the removal of nickel.
  • 摘要：The coliquefaction of Xianfeng coal with low-density polyethylene (LDPE) using　3H labeled solvent has been conducted. The effects of FAMo and Fe2O3+S catalysts, and solvents were examined. The　3H concentration in the reaction products was determined by a liquid scintillation counter to study the hydrogen transfer pathway. The results show that in the primary reaction of coal coliquefaction with LDPE, the coal was thermally decomposed and hydrogenated by hydrogen atoms mainly released from the solvent, tetralin (THN), and this hydrogen supplied from tetralin was not influenced by the catalyst. When the mixture of hydrogenated anthracene oil (HAO) and tetralin was used as the coliquefaction solvent in the presence of FAMo catalyst, the competitive transfer of hydrogen from strong donating hydrogen solvent, HAO, to the primary coliquefaction products occurs at the initial liquefaction reaction stage.%采用放射性同位素3H标记的四氢萘溶剂进行了先锋褐煤与低密度聚乙烯（LDPE）的共液化示踪试验，并考察了钼灰（FAMo）和Fe2O3+S催化剂的影响。应用液体闪烁计数器测量了各液化产物中的放射性活度，以研究煤与废塑料共液化中的氢转移。结果表明：在先锋褐煤与LDPE塑料共液化反应的初始阶段，存在着四氢萘溶剂的供氢作用，而且这种供氢作用不受催化剂的影响，只是热力作用的结果。使用加氢蒽油（HAO）和四氢萘（THN）溶剂混和物作为共液化溶剂时，先锋褐煤与LDPE共液化反应初期的溶剂供氢还存在着竞争转移，其主要取决于溶剂的脱氢能力。

  • 摘要：This paper introduces the effect of dolomite and limestone on waste tyre pyrolysis. When waste tyre was pyrolyzed in 700?℃, the derived gases was passed through the catalyst zone in which the temperature was controlled at 700?℃, 800?℃and 900 ℃, respectively. It is found that both dolomite and limestone affect the product distribution of tyre pyrolysis with erhancing gas yield and effective absorption of H2S. The effect of these catalysts on tar cracking is obvious at 900 ℃, however, the life of catalyst is short. The product yields are about 40% for gas, 30% for liquid and 30% for char in the presence of dolomite and limestone. The result indicates that multi-use of the pyrolysed product is highly recommended.
  • 摘要：甲醇自热重整制氢反应是车载燃料电池氢源的理想方式。本文应用ZnO/Cr2O3催化剂MOR-67上的宏观动力学，模拟分析了甲醇自热重整制氢反应器，合适的反应器为绝热径向反应器。对于本反应器一维拟均相模拟结果表明：适宜的水/醇比为2（常压）或3（低压）；压力：0.2 MPa～0.3 MPa。%The coupling of oxidation of methanol (a strong exothermic process) with the steam reforming reaction(a high endothermic process) is an attractive route for H2 production in terms of energy minimization. Analysis showed that the radial reactor is the most attractive configuration for on-board H2 generation. Using a one-dimensional homogeneous model, the paper discussed the performance of this self-evident process. The optimal rate of water to methanol and pressure are 2 (under normal pressure) or 3 (when P>1?atm) and 0.2?MPa～0.3?MPa, respectively.
  • 摘要：@@ 分子烙印技术的基本思想是源于人们对抗体—抗原或酶的专一性的认识，即一种抗体只能针对一种抗原，一种酶只能选择性的催化一种或固定的几种底物，而分子烙印技术则通过人工的方法合成与目标分子耦合的大分子化合物：以目标分子为模板，将具有结构互补的功能化聚合物单体分子通过共价键或非共价键的方式与模板分子结合，加入单体进行聚合反应，反应完成后将模板分子提取出来后形成具有空穴的能识别模板分子的高分子。用这种基于仿生方法合成的大分子聚合物即为分子烙印聚合物，它与模板分子的位置，形状，官能团互补［4］，对模板分子具有高度的选择性，即使难于分离的手性异构体也可用分子烙印聚合物进行分析分离［5］；此外分子烙印聚合物具有高度的稳定性，在高温、高压、酸、碱及高浓度离子等各种恶劣条件下也能保持其原有的特性［6］。它能反复使用达100次之多，在室温下保藏8个月而记印能力不变［7］。rn 分子烙印技术方面的研究吸引了各国学者的广泛兴趣，Klaus Mosbach 等人在这方面开展了广泛的颇有成就的工作，世界各地参与这方面研究的机构越来越多，研究的领域也越来越广，1998年，欧洲的一些研究分子烙印聚合物技术的项目组还被纳入资助计划。综合起来，目前对分子烙印技术的研究主要集中在分子烙印聚合物的制备、应用以及烙印过程的机理等。
  • 摘要：采用国产大孔磺酸树脂(NKC-9)，在无梯度反应器内对异戊烯与甲醇醚化反应进行了研究。在消除内扩散和外扩散的情况下，考察了甲醇浓度对醚化反应速率的影响。根据LHHW机理和均相反应机理推导出相应的模型方程，经模型筛选和参数估值，得出LHHW模型为最佳模型。在该模型中反应速率的实验值与模拟值有较好的一致性。%The etherification reaction of methanol and isoamylene was investigated in an internal recycle gradientless reaction with an ion exchange resin (NKC-9) as catalyst. The effect of methanol concentration on the etherification was discussed. The results showed that the reaction rate decreased to a minimum with increasing methanol concentration and then had a slowly increase by further increasing of methanol concentration. Two rate equations were drive by LHHW and homogeneous phase mechanisms. The experimental results, which were in a good agreement with the calculated results, were found to be best described by the kinetic equation following the Langmuir-Hinshelwood-Hougen-Watson model, in which all reagents, methanol, isoamylenes and ether absorbed on the catalyst active sites.

  • 摘要：煤炭地下气化过程中，高温的碳与二氧化碳和水蒸气发生的非均相反应决定了出口煤气的组分和热值。鉴于此，在煤焦与CO2和H2O(g)反应活性实验的基础上，研究了唐山刘庄煤焦与CO2和H2O(g)气化反应的动力学特性，确定了其化学反应的速率表达式，得出其反应活化能分别为140.41 kJ/mol和171.53 kJ/mol。实验结果表明，还原带温度在1 000 ℃～1 100 ℃时，CO2具有较高的还原率；当温度达到1 000 ℃时，H2O(g)分解可视为不可逆反应，且生成CO的反应速率明显大于生成CO2的反应速率，出口煤气组成中CO的浓度为CO2的7倍多。在上述工作的基础上，建立了“收缩反应核”模型，并分析了多相化学反应速度与温度的关系。%The kinetic character of CO2 reduction and H2O(g) decomposition in Liuzhuang underground coal gasification at Tangshan is studied on the basis of the experiment for reaction activity of coal coke and CO2 and H2O(g). The test apparatus, method and test procedure are introduced, and kinetic parameters of the gasification reaction for CO2 and H2O(g) have been calculated, the expressions for reaction rate is determined, and the activation energy obtained is 140.41?kJ/mol and 171.53?kJ/mol, respectively. Based on the diffusion-kinetics theories, “contraction reaction nucleus” model is established, and the relation between polyphase chemical reaction rate and temperature is analysed. The results indicate that there is a higher reduction rate for CO2 when the temperature range of reduction zone is 1?000?℃～1?100?℃ and decomposition reaction of H2O(g) is regarded as irreversible one when the temperature reaches 1?000?℃. The reaction rate of CO generation is obviously higher than that of CO2 formation. The concentration of CO in gas compositions at vent is more than seven times higher than that of CO2. The calculation value by the model can be well identical with the experiment result, which proves the correctness and rationality of the “contraction reaction nucleus” model.
  • 摘要：Carbon tetrachloride is an ozone-depleting chemical, while chloroform is not. Therefore it is important for the catalytic hydrodechlorination of CCl4 to CHCl3. In this paper, kinetics on the catalytic hydrogenation of carbon tetrachloride to chloroform in liquid phase was studied. A reaction mechanism was proposed. Hydrogen molecular was activated on the surface of catalyst, the activated hydrogen atom then reacted with CCl4 in the solution and produced CHCl3. A definite kinetic equation could be deduced from the reaction mechanism. The reaction rate constant is concerned with the intial concentration of CCl4 in the solution, pressure, reaction temperature and the concentration of active center. All these factors were investigated over Pt-Pd/C catalyst and fit in with the kinetic equation. The activation energy of the reaction is 86?KJ/mol according to the experimental results.
  • 摘要：The aquathermolysis reaction of heavy oils obtained from Liaohe oil fields in China is studied at 240?℃.The results show that Liaohe heavy oils have been undergone visbreaking during the process. After treatment with steam, the viscosity of the heavy oil is reduced by 28%～42% and the amount of the saturate and aroomatic hydrocarbons is increased. The gas partition chromatography (GPC) results indicate that after reaction the accumulated amount of carbon numbers less than C25 is 50.97% in comparison with 17.93% before reaction. The results provided the basis data for recovery heavy oil by in-situ catalytic method in production heavy oil in oilfields.%报道了在水蒸汽作用下辽河油田稠油发生的化学变化。研究结果表明，稠油在水蒸汽作用下，其组成中饱和烃、芳香烃含量增加，胶质沥青质含量减少，粘度下降28％以上。气相色谱分析结果表明，稠油经水蒸汽作用后，其累积碳原子数少于C25的已经达到50.97%，远远超过处理前的17.93%。这为进一步实现稠油井下催化降粘开采提供了依据。
