摘　　要：我国石化企业催化裂化装置配置权重大,催化裂化柴油(LCO)芳烃和氮含量高、密度大、十六烷指数低,加氢精制困难,同时国内柴油需求下降,必须找出合适的加工方法处理LCO。中国石化茂名分公司采用中石化(大连)石油化工研究院有限公司开发的FD2GLCO加氢转化技术,对闲置的加氢裂化装置进行改造,加工LCO原料,生产高辛烷值汽油,副产清洁柴油和气体产品。改造后装置运行平稳,产品合格,成功消减柴油约400kt/a,达到了增产汽油、解决柴油出厂困难难题和增加企业效益的目的。The proportion of fluid catalytic cracking(FCC)units in petrochemical enterprises is very large.The high content of aromatic and nitrogen,high density and low cetane index of FCC light cycle oil(LCO)make hydrorefining difficult.Furthermore,the domestic demand of diesel is decreasing,it is necessary to find a suitable method to deal with LCO.The Maoming branch of SINOPEC used the FD2G LCO hydrogenation conversion technology developed by SINOPEC(Dalian)Research Institute of Petroleum and Petrochemicals Co.,Ltd.to retrofit its idle hydrogenation units to process LCO feedstock and produce high octane gasoline,by-product clean diesel and gas products.The unit run smoothly,the product was qualified,the diesel oil was reduced about 40o kt/a successfully.The aim of increasing gasoline production,solving the problem of diesel oil leaving the factory and increasing the benefit of the enterprisewas achieved.
