摘要:
一种耐硫一氧化碳变换催化剂,由以下原料制得:镁源、铝源、助熔剂氧化物、晶体生长剂、稀土助剂、CoO、MoO_3和酸性水溶液,还提供了一种制备该催化剂的方法:①向镁源、铝源、助熔剂氧化物和晶体生长剂中加入酸性水溶液和稀土助剂,进行混捏;②将①中的混合物进行挤条;③烘干②中得到的挤条产品;④对③中得到的烘干的半成品进行焙烧,得到催化剂载体;⑤在催化剂载体上等体积浸渍CoO和Mo03;⑥对⑤得到的产品进行焙烧。助熔剂氧化物和晶体生长剂,能够参与镁源和铝源形成镁铝尖晶石结构的固相反应中,提高镆铝尖晶石的机械强度和稳定性,而纳米级的活性组分有效提高了活性组分的分散度,改善活性组分颗粒界面的催化活性。

摘要:
为提升耐硫甲烷化催化剂活性,华烁科技股份有限公司开发出NSM-42型Ni-Mo系耐硫甲烷化催化剂,并在常压管式反应评价装置上对该系列催化剂进行了性能研究.测试了反应温度、空速、进料比等操作条件对NSM-42型催化剂性能的影响,并对改进的NSM-43型催化剂进行了30 h寿命试验.试验结果显示,随着反应空速的增加,NSM-42型催化剂反应活性下降;在反应温度350 °C~400 °C、催化剂焙烧温度375 °C、高氢碳比下,催化剂表现高的甲烷化活性;NSM-43型催化剂30 h寿命试验的前20 h,CO转化率可达99%,CH4选择性可达78%.%In order to improve the activity of the sulfur-tolerant catalyst for methanation, NSM-42 Ni-Mo based methanation catalysts had been developed by Haiso Technology Co., Ltd. and these catalysts had performance test at the atmospheric tubular reaction evaluation device. The effects of reaction temperature, space velocity, feed ratio and other operating conditions on the performance of NSM-42 catalyst were tested, and then 30 h life test was made on the improved NSM-43 catalyst. The test results showed that with the increase of reaction space velocity, the reaction activity of NSM-42 catalyst was decreased; the catalyst exhibited high methanation activity with the reaction temperature between 350°Cand 400°C, catalyst calcination temperature at 375 °C and high carbon hydrogen ratio. For NSM-43 catalyst, in the first 20 h of reaction, the CO conversion rate was up to 99% and the CH4 selectivity was up to 78%.

摘要:
采用沉淀-浸渍法合成一系列Ni-Mo基双金属催化剂,在固定床反应器中对其催化活性和耐硫性能进行评价,并辅以不同的表征手段阐释其作用机理.实验结果表明,以MCM-41分子筛为载体的催化剂活性和稳定性优于以NaY、γ-Al2O3和拟薄水铝石(PB)为载体的催化剂;反应前后催化剂的表征结果则说明Ni-Mo分子间适宜的相互作用是决定催化剂性能的关键.MCM-41载体催化剂中适宜的Ni-Mo分子间相互作用使得此催化剂中活性组分与载体间的相互作用适中,还原后的活性金属Ni能够均匀分散在载体表面,从而提高了催化剂的耐硫稳定性和抗积炭能力.不同Ni-Mo比同样会影响Ni-Mo分子间的相互作用,通过考察确定20Ni-10Mo/MCM-41的活性和稳定性最优.

摘要:
采用共沉淀法对铈铝复合载体进行放大制备,考察制得的复合载体成型后负载Mo基催化剂的放大制备效应.结果表明,催化剂进行逐级放大制备过程中,CO转化率略降,放大效应不大.对催化剂进行表征发现,小试制备的载体酸强度略高于放大制备的载体酸强度,说明Al的不饱和配位键较多,更加有利于活性组分的负载和CO的吸附.另外,与小试制备催化剂相比,催化剂放大制备后,MoO3颗粒尺寸略增,这是导致放大制备后催化剂催化反应活性略降的原因之一.

摘要:
制备非Mo基的CeO2-ZrO2催化剂,在固定床反应器于650°C,3MPa,GHSV=5000h-1,V (H2)/V (CO)=1.0且含有体积分数为0.6%的H2S的合成气中考察催化剂制备方法、成分比例和热稳定添加剂(La、Mg、Y)对其高温耐硫甲烷化性能的影响.采用N2物理吸附、H2程序升温还原、X射线衍射对催化剂进行了表征.结果表明,共沉淀法制备的催化剂(CeO2-ZrO2)比浸渍法制备的催化剂(CeO2/ZrO2)的高温甲烷化活性高,稳定性好.XRD表征发现,共沉淀法制备的CeO2-ZrO2催化剂能形成类合金.共沉淀过程中添加La助剂有利于提高催化剂的热稳定性.%The non-Mo-based catalysts--modified CeO2-ZrO2 were prepared,and the effects of preparation methods,proportions of components and thermal stability additives (La,Mg,Y) on the performances of the catalysts for high temperature sulfur-resistant methanationin were investigated in a fixed-bed reactor under the reaction conditions of 650°C,3MPa,GHSV of 5000h1 and the syngas with the H2/CO volume ratio of 1.0 and containing H2S of 0.6% by volume.The results indicate that the catalysts prepared by co-precipitation (CeO2-ZrO2) have better activity and stability than the catalysts prepared by impregnation (CeO2/ZrO2) during the methanation reaction at high temperature.XRD results show that the co-precipitated CeO2-ZrO2 catalysts can form metal alloy.In the process of co-precipitation adding La additive can improve the thermal stability of the catalyst.

摘要:
对高温活性好、耐硫强、热稳定性好、机械强度高和寿命长的NIC6高温耐硫甲烷化催化剂进行了本征动力学研究。以鲁奇炉出口气体组分为参照,采用等温积分反应器,在460~560°C、2.0~3.5MPa、ψ(H2S)=0.4%、气体流量1.05~1.4mol/h条件下,通过气相色谱测定反应器出口各组分的浓度。得到幂函数动力学模型及活化能和指前因子。该函数模型的检验表明结果是合理的,参数回归显著,残差分布均匀。%The intrinsic kinetics of sulfur-tolerant methanation catalyst NIC6 was studied. The catalyst NIC6 shows high activity at high temperature. An isothermal integral tubular reactor was employed to test the catalyst and get experimental data. The components of the feed gas and the reaction tail gas were analyzed by gas chromatography. The catalyst was tested under the reaction conditions of 460~550°C, 2.0~3.5MPa, H2S volume fraction of 0.4% and gas flow rate of 1.05~1.4mol/h. A power function kinetic model was established from the experimental data, and the activation energy and pre-exponential factor were obtained. The model testing show that the results are reasonable. The parameters are regressed significantly and the residual distribution is uniform.
