摘要: 介绍中国石化石油化工科学研究院开发的增强型催化裂解技术(DCC-PLUS)的特点以及首套DCC-PLUS工业装置的生产运行情况及标定结果。结果表明,DCC-PLUS工艺很好地满足了增产低碳烯烃、少产汽油、柴油的生产需要,其中丙烯收率由原设计的15.50 %提高至18.22%,汽油、柴油收率由原设计的45.10%降低至39.07%,干气产率和焦炭产率保持在较低的水平。

关键词: DCC-Plus 技术, 丙烯, 低碳烯烃

Abstract: The concept of DCC-Plus technology developed by SINOPEC Research Institute of Petroleum Processing (RIPP) and the first industrial application of the technology were introduced. The results from DCC-Plus units showed that compared with DCC technology, the DCC-Plus could meet the demand of increasing the production of low carbon olefins while decreasing gasoline and diesel fuel. The yield of propylene rose to 18.22% in DCC-Plus process from 15.50% of the original design, the total yields of gasoline and diesel were reduced to 39.07% from 45.10%, respectively, and the yields of dry gas and coke remained low.

Key words: DCC-Plus technology, propylene, light olefins
