离子液体催化C_4烷基化油中氯代烃的燃烧产物分析
|
摘要
近年来,对离子液体催化异丁烷与丁烯生产烷基化油的研究日益活跃,然而这种新型工艺生产的烷基化油含有一定量的氯代烃。采用热力学计算及过程模拟探究了含氯代烃烷基化油在发动机气缸内燃烧产物的分布情况,以探明产生含氯有害物质的种类、条件、可能性及生成量。研究结果对于改进离子液体催化C4烷基化工艺及开发新型的汽车尾气净化装置均具有指导意义。
The development of alkylated oil from isobutane and butene catalyzed by ionic liquids is increasingly active in recent years. However, there exist a considerable amount of chlorinated hydrocarbon in alkylation oil produced by this process. In this paper, the distribution of the final product after combustion of chlorinated alkylated oil in car engine was investigated by thermodynamic calculation and process simulation. Finally, the types, possibility of generation and quantities of harmful substances were determined by the analysis on the calculation results under the different simulation conditions. The results of this work is of great importance to effectively improve the technology of C4 alkylation catalyzed by ionic liquid and develop the new automotive exhaust purifier.
