摘要
介绍了催化裂化(FCC)工艺增产丙烯的主要思路,围绕这些思路综述了增产丙烯的工艺改造进展。包括深度催化裂化(DCC),催化热裂解技术(CPP),重质油接触裂解(HCC),PetroFCC,选择性组分裂化(SCC),Maxofin,高苛刻度FCC(HS-FCC),Superflex等工艺,并将这些工艺流程特点、使用的催化剂、产品分布和烯烃产品收率与常规FCC工艺相比较,结果表明,丙烯收率均有明显提高。并指出通过FCC工艺技术改造增产丙烯是适合当前我国国情的技术路线。
The main ideas to increase propylene yield with fluid catalytic cracking（ FCC ） were introduced. The advances in technology of increasing propylene yield were discussed, including deep catalytic cracking （ DCC ） , catalytic pyrolysis process （ CPP）, heavy - oil contact cracking（ HCC）, Petro fluidized catalytic cracking （ PetroFCC ）, selective component cracking （ SCC ）, Maxofin, high - severity fluid catalytic cracking（ HS - FCC）, Superflex , etc. The technologic characteristics, catalyst, components of product, and olefin yield of new technologies were compared with those of general technology of FCC. The results showed that the yield of propylene was increased obviously in modified technologies. The modified technical process is suitable for application in China.
