摘　　要：中国石油兰州化工研究中心研发出适合MIP-CGP(生产清洁汽油组分并多产丙烯)催化裂化(FCC)工艺使用的LDR-100催化剂,并在该中心XTL-5型提升管FCC中试装置上评价了该催化剂的性能。结果表明,与现有专用催化剂相比,使用LDR-100催化剂,在m(催化剂)/m(原料油)为6.9,反应温度为520℃,反应时间为1.82 s的相同工艺条件下,重油产率可降低1.45个百分点,丙烯产率可提高0.74个百分点,汽油的烯烃体积分数可降低6.13个百分点,汽油的研究法辛烷值可提高0.7个单位,显示出了较好的综合反应性能。本工作为使用二段提升管MIP-CGP工艺的FCC装置提供了一种选择催化剂的新途径。Catalyst LDR-100 tailored for a novel fluidized-bed catalytic cracking（FCC） process to significantly reduce olefin content in FCC gasoline and enhance propylene yield（MIP-CGP） was prepared and evaluated in the XTL-5 pilot riser of Lanzhou Petrochemical Research Center,PetroChina.The results showed that compared with specialty catalyst,LDR-100 could reduce heavy oil yield by 1.45 percent points,increase propylene yield by 0.74 percent points,reduce olefin volume fraction in FCC gasoline by 6.13 percent points,increase research octane number by 0.7 units under the same conditions of m（catalyst）/m（stock oil） of 6.9,temperature of 520℃ and time of 1.82s as those for specialty catalyst,exhibiting better all-round properties.
