摘要
综述了国内外双提升管催化裂解工艺技术进展,包括国内灵活多效催化裂解(FDFCC)系列技术、增强型催化裂解技术(DCC-plus)、两段提升管催化裂解多产丙烯技术(TMP)及国外Maxofin-FCC工艺、PetroRiser工艺及PetroFCC工艺。重点介绍了旨在解决催化剂与原料油精确匹配问题的双催化剂分区再生工艺技术,并指出今后的研发应注重:优化双提升管催化裂解分区再生装置的工艺参数,以降低操作难度;根据市场需求,实现不同技术方案在同一装置上的灵活切换,以加快工业化进程。
The research progress on dual-riser fluid catalytic cracking technology at home and abroad was reviewed,including the domestic flexible dual-riser fluid catalytic cracking(FDFCC)series technology,the enhanced deep catalytic cracking(DCC-plus)technology,the two-stage riser catalytic cracking for maximizing propylene(TMP)technology,and the foreign Maxofin-FCC process,PetroRiser process and PetroFCC process.Then the dual catalyst partition regeneration technology was emphatically introduced,which aiming to solve the problem of precise matching between catalyst and feedstock.It was pointed out that the future research&development of such dual catalyst partition regeneration process technology should pay attention to the following aspects:further optimize the process parameters of the dual-riser catalytic cracking partition regeneration unit so as to reduce the difficulty of operation;the different technical solutions could be flexibly switched on the same device according to market demand,so as to speed up the industrialization process.
