摘　　要：催化裂解工艺DCC是以重质油为原料,利用选型催化剂制取低碳烯烃的新技术。其中催化裂解DCC-Ⅰ型以生产最大量的丙烯为主要目的,催化裂解DCC-Ⅱ型以生产最大量异丁烯和异戊烯、兼产丙烯和高辛烷值优质汽油为目的。催化裂解采用双提升管反应器开创了一条以重质油为原料直接制取低碳烯烃的新途径。Catalytic cracking process DCC is based on heavy oil as raw material,new technology of making low carbon olefin by type selection catalyst.The main purpose of the catalytic cracking of DCCtype-Ⅰ is to produce the most large amount of propylene.The purpose of catalytic cracking DCC-Ⅱ is to produce the maximum isobutene and isoamyl,and also produce propylene and high octane high quality gasoline.A new way of direct production of low carbon olefins with heavy oil as raw material is created by using double riser reactor for catalytic cracking.
