多产重石脑油和喷气燃料加氢裂化技术的工业应用

为应对市场需求变化，中国石油四川石化有限责任公司于2018年采用中国石化石油化工科学研究院开发的多产重石脑油和喷气燃料加氢裂化技术对2.7 Mt/a加氢裂化装置进行了技术改造。装置开工满14个月的初期标定结果表明：在控制尾油收率为18.86%的情况下，装置的重石脑油收率为29.47%；喷气燃料收率为36.24%，较上周期提高11.48百分点，其性质符合3号喷气燃料指标要求；尾油的BMCI为7.8，是优质的蒸汽裂解制乙烯原料。采用该技术后装置实现了在压减柴油的同时增产重石脑油和喷气燃料、改善化工原料质量的目标。

COMMERCIAL APPLICATION OF HYDROCRACKING TECHNOLOGY FOR IMPROVING HEAVY NAPTHA AND JET FUEL YIELD

In order to satisfy the increasing market demand of jet fuel and chemical materials, the hydrocracking technology for improving heavy naphtha and jet fuel yield developped by SINOPEC Research Institute of Petroleum Processing was applied in 2.7 Mt/a hydrocracking unit of PetroChina Sichuan Petrochemical Company in2018. The caliberation results after 14 months operation illustrated that with unconverted oil yield of 18.86%, heavy naphtha yield was 29.47%; the jet fuel yield reached 36.24%, 11.48 percentage points higher than the last operation cycle and met the requirements of No.3 jet fuel. The unconverted oil with BMCI value of 7.8 was the high quality feedstock for steam cracking. The goal of increasing heavy naphtha and jet fuel yields was achieved while reducing diesel oil and improving the quality of chemical raw materials.
