摘　　要：结合加氢裂化扩能生产喷气燃料对原料来源的需求,以减压蒸馏生产优质加氢裂化原料为出发点,对减压蒸馏技术增产优质减压蜡油进行优化。结果表明:在相同的操作条件下,减二线、减三线、减四线蜡油总收率约提高0.5%(对进料),在一定程度上达到了减压深拔的要求;减二线蜡油收率提高3.78%,且质量得到大幅改善,满足加氢裂化原料指标要求,达到了增产加氢裂化原料的目的。Optimization on the vacuum deep distillation technology was conducted to increase high quality hydrocracking raw material for producing jet fuel. Through the optimization, under the same operation conditions, the total yields（feed as a benchmark）of vacuum side cut 2, 3 and 4 are increase by 0.5%, reaching the extent of vacuum deep distillation. The VGO yield of side cut 2 increases by 3.78% with significantly improved quality, meeting the requirement for hydrocracking feedstocks.
