催化裂化汽油加氢改质的热力学研究

Thermodynamic research on hydrogenation upgrading of FCC gasoline

根据加氢异构化和环化(芳构化)机理以及集总反应网络的原理,以正庚烷和1-庚烯为模型化合物,分析了烷烃异构化、芳构化,烯烃异构化和芳构化反应的有利途径。通过热力学分析计算得知,低温有利于加氢和异构化,高温有利于芳构化,烯烃比烷烃易于反应。

Based on the mechanism of hydrogenation isomerization and cyclization(aromatization)and the principle of lumped reaction network,with normal heptane and 1-heptene as model compounds,this paper analyzed the advantageous approaches to the alkane isomerization,aromatization,the olefin isomerization and aromatization.It is known through that low temperature is in favor of hydrogenation and isomerization,high temperature is in favor of aromatization,and olefin is easier to react than alkane.
