摘  要:针对中国石化天津分公司MIP装置工况、原料油性质特点以及对产品分布和产品性质的要求,设计开发了抗碱氮多产丙烯MIP工艺专用催化剂CRMI-Ⅱ(TJ)。工业应用结果表明:以中间基蜡油掺20%~30%的焦化蜡油和10%~20%的常压渣油为原料,使用CRMI-Ⅱ(TJ)专用催化剂后,稳定汽油烯烃体积分数大幅度降低,可以达到35%以下,总液体收率(液化气+汽油+柴油)达到87%以上,稳定汽油辛烷值RON达到92以上。与参比剂相比,CRMI-Ⅱ(TJ)催化剂具有更好的焦炭选择性、抗碱氮中毒、提高汽油辛烷值和增产丙烯性能。Based on the unit operation conditions, feedstock properties, the requirements of product slates and product properties in Tianjin Petrochemical Corporation, CRMI-Ⅱ (TJ) catalyst, a catalyst specially tailored for MIP technology to process feedstock with high coker gas oil(CGO) blending, was developed. The commercial application results showed that using CRMI-Ⅱ (TJ) catalyst, when processing an intermediate base feedstock blended with 20%--30% CGO and 10%-20% AR,the total liquid yield reached more than 87% ,the obtained stabilized gasoline had an olefin content of less than 35% and RON over 92. As compared with reference catalyst(base case),CRMI-Ⅱ (TJ) catalyst exhibited better coke selectivity, good basic nitrogen tolerance, enhanced gasoline octane number and higher propylene yield.
