摘　　要：中国石化上海石油化工股份有限公司为提高1.5 Mt a中压加氢裂化装置的效益,在本周期生产中优化产品结构,压减柴油、多产喷气燃料,对装置进行了催化剂级配和分馏系统适应性改造,进行了中等压力条件下以蜡油为原料生产喷气燃料技术的工业应用。标定结果表明:采用新技术加工终馏点约517℃、BMCI约45的中间基蜡油原料,在高压分离器压力为10.7 MPa的中等压力条件下,所得喷气燃料收率为21%,烟点为25 mm,萘系烃质量分数低于0.5%,满足3号喷气燃料质量要求;尾油收率为27%,BMCI为10,为优质的蒸汽裂解制乙烯原料。In order to improve the efficiency of the 1.5 Mt a medium pressure hydrocracking unit,SINOPEC Shanghai Petrochemical Co.Ltd.optimized the product structure by reducing diesel fraction and producing more jet fuel in the production cycle through improving the catalyst grading option and reforming the fractionation system,and the commercial application of medium pressure hydrocracking technology for jet fuel production with VGO feed was carried out.The calibration results showed that using the new technology,with the intermediate base VGO with final distillation point of 517℃and BMCI of 45 as feed,under the pressure of high-pressure separator of 10.7 MPa,the yield of jet fuel was 21%with the smoke point of 25 mm and naphthalene hydrocarbons mass fraction of less than 0.5%which could meet the quality requirements of No.3 jet fuel,and the yield of tail oil was 27%with the BMCI of 10,which could be used as superior feed of steam cracking unit to produce ethylene.
