    • 摘要: 1表面活性剂在乳化油中的应用1.1表面活性剂在燃油乳化中的应用柴油中掺入一定比例的水用做发动机燃料已被实验证实,不仅可节约柴油消耗,而且显著减少排气中有害物(氮氧化物、一氧化碳、碳氢化合物等)排放量,有利于环境保护。乳化柴油的节油原理为:油包水型分散体系受热时水“爆裂”,提高柴油雾化效率,进而使燃烧效率提高。同时,高温下不完全燃烧的碳颗粒与水反应产生一氧化碳和氢气也可参与燃烧,提高燃料反应效率。

    • 摘要: 柴油在发动机中的燃烧是不完全和不完善的,由于甲醇的参与,乳化油的燃烧就更加完全和充分.本实验通过对用甲醇、柴油、水、乳化剂、助乳化剂按一定配比在乳化机中乳化形成的乳化油进行台架对比测试,测试柴油机推进特性实验下的经济性、排放性和动力性能.实验结果表明,乳化油的节油率和减排效果非常明显.

    • 摘要: The characteristics of combustion and spray,power performance,fuel economy and emission characteristics for e-mulsified diesel were reviewed,the differences of engine fueled with conventional and emulsified diesel and their causing factors were analyzed,and the application and optimization methods of emulsified diesel in diesel engine were finally summarized.The results showed that the ignition delay and combustion duration period of emulsified diesel delayed and shortened respectively.In addition,spray penetration of emulsified diesel was almost the same as or longer than that of pure diesel and its flame height al-so increased.The power of diesel engine decreased,but the brake thermal efficiency improved after being fueled with emulsified diesel.The NO xand soot emissions reduced and the HC and CO emissions increased at most operating points,especially at low speed and medium and low load.The total particle number concentration increased,the particle volume fraction decreased and the aldehyde and noise emissions were little influenced.The addition of appropriate additives or the introduction of engine col-laborative technology could improve the combustion process of emulsified diesel and hence the low fuel consumption and emis-sion were realized.The fuel design based on fuel stability and physiochemical features and the optimization of combustion pa-rameter for high pressure common rail diesel engine fueled with emulsified diesel would be concerned in the future.%综述了柴油机燃用水乳化柴油的燃烧与喷雾特性、动力性与经济性及排放特性,对比分析了发动机燃用水乳化柴油与普通柴油在性能上的差异及其原因,总结了水乳化柴油在柴油机上的应用优化方法.结果表明:与柴油相比,乳化柴油着火滞燃期延迟,燃烧持续期缩短,喷雾贯穿距变长或相差不大,火焰升起高度增加;燃用乳化柴油时动力性下降,但有效热效率较柴油升高;乳化柴油可以明显降低NO x和炭烟排放,但多数工况下 HC和CO排放有所升高,低转速和中低负荷工况下尤为明显;燃用乳化柴油时颗粒物数量浓度增加,体积浓度减小,且对于醛类和噪声排放并没有改善作用;添加合适添加剂或结合发动机技术协同作用,可以针对性地改善乳化柴油的燃烧过程,进一步起到节能减排的效果.基于燃料稳定性与燃料理化特性综合优化目标的燃料设计,以及适用于乳化柴油的高压共轨柴油机燃烧组织参数优化是未来的研究方向.

    • 摘要: 针对渤海油田疏松砂岩油藏油层厚度大、非均质性严重、酸化后含水率上升的问题,开展了乳化柴油封堵分流能力实验研究.物理模拟实验表明,以油水体积比3:7制备的乳化柴油体系具有选择性封堵高渗透层,对低渗油层的封堵能力较弱.应用该体系后可有效将后续液体分流到低渗层,且对高渗水层的渗透率有较大幅度降低,而对低渗油相渗透率影响很小.与常规酸化解堵措施相结合,可起到均匀酸化与控水增产的目的.%Research on the technique of emulsified diesel temporary plugging and diversion capacity was carried out in this paper.The new technology attempted to improve acidizing effectin Bohai oilfields,which was unconsolidated sandstone reservoirs with thick oil layers,serious anisotropy and high water-cut after acidification.The physical model lab test indicated that the emulsion diesel system with oil-water ratio 3:7 had a good capacity of selectively plugging in high permeability layers and little plugging effect on the low permeability layers.This can lead following fluids steering to the lower permeability layer. Integrated with conventional acidizing treatments, the emulsion diesel system can also conduce to uniformly acidizing treatment,water control and stimulation.

    • 摘要: 选取动力煤选煤厂煤泥为研究对象,利用傅里叶红外光谱(FTIR)仪和接触角测量仪对比了超细粉碎后的煤泥以及和乳化柴油作用后的煤泥的官能团和润湿性的变化,分析了在絮团浮选中乳化柴油的作用机理.在此基础上,研究了乳化柴油的种类和用量以及分散剂或起泡剂的添加对煤泥絮团分选超净煤的影响.试验结果表明,乳化柴油中的非离子型表面活性剂极性基与煤表面的含氧官能团发生氢键吸附,使煤表面含氧官能团含量减少,接触角增大,疏水性增强;1#乳化柴油的浮选效果优于2#乳化柴油;1#乳化药剂的最佳药剂用量为57.96 kg/t;在分选过程中添加分散剂后得到的超净煤灰分减小,产率也减小;添加起泡剂后分选效果优于单独使用乳化柴油的分选效果.%The authors took coal slime of steam coal preparation plant as object of study, used FTIR and contact angle goniometer to compare the changes of functional groups and wetta-bility of coal slime with or without adding the emulsified diesel oil after ultrafine grinding,ana-lyzed functional mechanism of emulsified diesel during flocculation flotation,and based upon the experiment,studied the influences of types,dosages of emulsified diesel and addition of disper-sant or frother on coal slime flocculation separating ultra-clean coal. The results showed that the hydrogen bonding adsorption occurred between the nonionic surfactant polar groups in emulsified diesel oil and the oxygen-containing functional groups on surface of coal,which leaded reducing on content of oxygen containing functional groups on the surface of coal and increasing of the con-tact angle and wettability,therefore,the flotation results of 1 # emulsified diesel was better than the 2 # emulsified diesel,the optimum dosage of 1 # emulsified diesel was 57.96 kg/t,the ash of the ultra-clean coal with dispersants reduced during separation and the yield was decreased,and the separation results with adding frother was better than the separation results with single emul-sified diesel separately.

    • 摘要: The emulsified diesel fuel, which could be stably stored at room temperature, was prepared by homogenizer and mechanical stirring. The mass ratios of diesel, water and additives were determined. The fuel consumption on different working conditions of emulsified diesel were tested on engine test bench, and the oil-saving rates were determined. The physicochemical properties of the emulsified diesel fuel were measured and comparatively analyzed. The emulsified diesel were prepared when the additive content was 2 wt %, water blending ratio were 10 wt % and 15 wt %, respectively. The results showed that the oil-saving rates of emulsified diesel were different on various working conditions, and the highest oil-saving rate was 6% . The physical and chemical indexes of emulsified diesel fuel conformed to the national standard, and the emulsified diesel seemed clear and transparent, the stable period was more than one month.%采用均质机和机械搅拌相结合的手段制备了能够在室温下稳定储存的乳化柴油,确定了柴油、水、添加剂的配比。对制得的乳化柴油在发动机台架上进行不同工况的油耗试验,确定节油率。对乳化柴油理化性能指标进行了测定。实验结果表明:添加剂为2 wt%,掺水率为10 wt%、15 wt%时制备的乳化柴油在不同工况下,均有不同程度的节油,最高节油率达到6%。乳化柴油理化指标符合国家标准,乳化柴油为澄清透明状态,稳定期可达一个月以上。
