摘要
催化裂化干气主要由氢气、甲烷、乙烯、乙烷等成分构成,当前对它的加工利用方式有两种:一是对其进行组分分离提纯,得到相应组分后再利用,二是在一定的温度、压力与催化剂作用下,直接加工生产成混合芳烃。催化裂化干气的再利用有效地避免了其直接燃烧造成的资源浪费,促进了生产企业经济利益的提升。本文就针对催化裂化干气第二种加工方法-干气芳构化制混合芳烃技术阐述其反应机理、所使用的催化剂,以及目前的工业应用情况,为催化裂化干气的再加工利用奠定一定的基础。
The FCC dry gas is mainly composed of hydrogen,methane,ethylene,ethane and other components.Currently,there are two ways to process and utilize in FCC Dry Gas:one is to separate and purify the components to obtain the corresponding components and reuse them;the other is to directly process and produce mixed aromatics under certain temperature,pressure and catalyst.Reuse of FCC dry gas effectively avoids waste of resources caused by direct combustion in FCC dry gas and promotes the evonomic efficiency of production enterprises.In this paper,the reaction mechanism,catalyst used and current industrial application of aromatization technology in FCC dry gas for the second processing method of FCC dry gas are described,which lays a certain foundation for the reprocessing and utilization of catalytic cracking dry gas.
