摘　　要：针对哈尔滨石化分公司600 kt·a^(-1)重油催化裂化装置降低汽油烯烃含量及提高辛烷值的需求,兰州化工研究中心开发了新型LDS-6HRB催化剂,并进行了工业应用。结果表明,在原料油性质相似、操作相近的条件下,汽油+轻柴油+液态烃收率增加0.31个百分点,油浆产率降低0.39个百分点;汽油烯烃体积分数由29.28%降低至25.63%,降低3.65个百分点,汽油研究法辛烷值增加0.6个单位。LDS-6HRB催化剂在哈尔滨石化分公司的成功应用可以为其他炼厂降低汽油烯烃含量及提高辛烷值提供优质参考方案。In order to reduce olefin content and increase octane number of gasoline in the 600 kt·a^(-1) heavy oil catalytic cracking unit of Petrochina Harbin Petrochemical Company, a new type of LDS-6HRB catalyst was developed by Lanzhou Petrochemical Research Center and applied in industry.The results show that under the similar properties of raw oil and similar operation conditions, total yield of gasoline, light diesel and liquid hydrocarbons increased by 0.31 percentage point, and the slurry yield decreased by 0.39 percentage points.The volume fraction of olefins in gasoline decreased by 3.65 percentage point(from 29.28 % to 25.63 %),and the octane number of gasoline increased by 0.6 units.The successful application of LDS-6HRB catalyst in Petrochina Harbin Petrochemical Company can provide an optional high-quality solution for other refineries to reduce olefin content and increase octane number of gasoline.
