摘　　要：中韩(武汉)石油化工有限公司(简称中韩石化)2号催化裂化装置具有反应时间较长、反应压力高和以加工加氢精制蜡油原料为主的特点,其汽油辛烷值低,丙烯、丁烯收率低。为了提高经济效益,装置催化剂改为采用中石化石油化工科学研究院有限公司开发的提高汽油辛烷值和多产丙烯、丁烯的催化裂化催化剂HBC-3WH。更换催化剂后,目标产物(液化气+汽油)收率提高1.04百分点,丙烯、异丁烯、正丁烯相对原料收率分别提高1.0,0.45,0.91百分点,焦炭产率基本不变,稳定汽油烯烃体积分数提高8.4百分点,研究法辛烷值提高2.3。The No.2 catalytic cracking unit of SINOPEC-SK(Wuhan)Petrochemical Company Limited had the characteristics of long reaction time,high reaction pressure and processing hydrogenated VGO feedstock,and the gasoline had low octane number and the yield of propylene and butene was low.In order to improve the economic benefits,the catalytic cracking catalyst HBC-3WH developed by SINOPEC Research Institute of Petroleum Processing Co.,Ltd.,was used to increase the octane number of gasoline and produce more propylene and butene.The commercial application results showed that the target product(LPG+gasoline)yield was increased by 1.04 percentage points,the relative yields of propylene,isobutylene and n-butene were increased by 1.0 percentage point,0.45 percentage point and 0.91 percentage point,respectively,the coke yield was basically unchanged,the olefin volume fraction in gasoline was increased by 8.4 percentage points,and the research octane number was increased by 2.3.
