催化裂化干气乙烯回收利用技术研究进展

The Development of Recovery and Utilization Processes of Ethylene in FCC Dry Gas

催化裂化干气中含有乙烯,其回收和利用问题已成为现今的研究热点。文章阐述了国内外催化裂化干气乙烯回收利用技术现状和最新进展,为更好得实现催化裂化干气的回收利用,应加强催化裂化粗乙烯利用工艺的开发研究。

FCC dry gas contains much ethylene, which recovery＂ and utilization has become research hotspot nowadays. The present situation and development of recovery and utilization process of ethylene in FCC dry gas were discussed in this work. In order to make better utilization of ethylene in FCC dry gas, process tbr crude ethylene in FCC dry gas should be enhanced.
