重油催化裂解生产低碳烯烃影响因素的研究进展

乙烯、丙烯等化工原料需求旺盛和成品油消费增速放缓促使炼化一体化成为石化行业发展的新方向，重油催化裂解生产低碳烯烃工艺在其中占据重要地位。从重油催化裂解反应机理着手，概述了原料、催化剂、反应器型式和工艺条件等因素对重油催化裂解产物分布的影响，并就重油催化裂解技术面临问题的解决提出展望。

RESEARCH PROGRESS ON FACORS AFFECTING DEEP CATALYTIC CRACKING OF HEAVY OIL TO LIGHT OLEFIN

The great demand of chemical raw material such as ethylene and propylene and moderating of oil consumption increase drive the petrochemical industry to a new direction of integration of refinery and petrochemical where the technology of producing light olefins from heavy oil deep catalytic cracking deserves a place. From the perspective of reaction mechanism, the effect of feedstock property, catalyst, reactor type, and operating conditions on the product distribution is summarized, and the challenges on the progress of deep catalytic cracking are prospected.
