剂油短时接触催化裂化工艺技术最新进展与探讨

The Latest Progress and Examination of Technology Over Catalyst/Oil SCT Catalytic Cracking

介绍了近年来在剂油短时接触方面出现的各种催化裂化技术,如提升管末端的油剂快速分离技术、急冷技术、SCT催化裂化技术、MSCC技术和下行床反应器技术,等等。并对今后剂油短时接触催化裂化技术的发展给予了初步的探讨。

The paper describes catalytic cracking technology of different kinds in catalyst/oil SCT in recent years such as quick separating technology of oil/catalyst at the far end of the riser, flash cooling technology, SCT catalytic cracking technology, MSCC technology and descending bed reactor technology. The paper also makes a preliminary examination of the development of catalyst/oil SCT catalytic cracking technology in the future.
