多产丙烯的催化裂化工艺进展

Advance of Fluid Catalytic Cracking Process for Maximizing of Propylene Yield

丙烯是重要的基本有机化工原料,近年来全球丙烯的年需求量一直持续增长。我国重油资源丰富,价格相对低廉,重油催化裂化多产丙烯技术受到广泛关注。论述了多产丙烯的催化裂化工艺进展情况,指出通过催化裂化工艺增产丙烯是适合当前我国国情的技术路线。

As an important basic organic chemical material,the global annual demand of propylene has been increasing constantly in the recent years.China has rich heavy oil resource which is relatively low in price,so the heavy oil fluid catalytic cracking（FCC）process for maximizing propylene yield has aroused extensive attention.This paper reviewed advance of FCC process for maximizing propylene yield,and pointed out that increasing propylene yield through FCC process was a technical route suitable for China＇s current status.
