MIP-CGP工艺专用催化剂CGP-1的开发与应用

阐述了生产汽油组分满足欧Ⅲ排放标准并多产丙烯的催化裂化工艺（简称MIP-CGP）专用催化剂（简称CGP-1）的研究开发与工业应用结果。CGP-1催化剂的基质具有良好的容炭性能，使活性组元受到良好保护，其优势作用在第二反应区得以充分发挥，具有更高的氢转移活性和强的汽油小分子烯烃裂化活性。中国石化九江分公司和镇海炼化公司的MIP-CGP工业试验标定结果表明，与常规FCC相比，采用CGP-1催化剂的MIP-CGP技术在生产烯烃体积分数小于18％的汽油组分的同时，丙烯产率达到8％以上。此外，汽油诱导期大幅提高，抗爆指数增加；总液体收率有所提高，干气产率下降，焦炭选择性良好。

DEVELOPMENT AND APPLICATION OF CGP-1 CATALYST TAILORED FOR MIP-CGP PROCESS

The development of CGP-1 catalyst tailored for a novel FCC process to significantly reduce olefin content in FCC naphtha and to enhance propylene yield (name as MIP-CGP process) were introduced. The matrix of CGP-1 catalyst possessed excellent capability to accommodate coke formed in the first reaction zone and protected the zeolite components. Thus, in the second reaction zone the catalyst exhibited high hydrogen transfer activity and good light olefins (in FCC naphtha) cracking activity. The commercial trial results of MIP-CGP process in Jiujiang Petrochemical Company and Zhenhai Refining and Chemical Company showed that the olefin volume content of naphtha was less than 18% and the propylene yield was more than 8%. Furthermore, as compared with the conventional FCC process, the induction period and antiknock index of the produced gasoline increased, a higher total liquid yield and a lower dry gas yield were obtained, and the coke selectivity improved. The advantages and characteristics of MIP-CGP process were fully exploited by using CGP-1 catalyst.
