摘　　要：采用全循环加氢裂化工艺处理直馏蜡油混兑焦化蜡油与催化柴油的混合劣质加氢原料,考查不同转化深度对产物分布与产品质量的影响。研究结果表明:全循环加氢裂化工艺可实现灵活生产柴油与航空煤油的生产目标。在最大量生产柴油的方案下,柴油产品收率为80%,十六烷指数可保持在58以上;在最大量生产航空煤油的方案下,合格航空煤油产品收率可达46%,副产柴油的十六烷指数高达79。Full-cycle hydrocracking process was used to treat the mixed inferior hydrogenation feedstocks of vacuum gas oil(VGO)mixed with coker gas oil(CGO)and FCC diesel.The effects of different conversion depths on product distribution and product quality were investigated.The results showed that the full-cycle hydrocracking process could achieve the production target of producing diesel oil and aviation kerosene flexibly.Under the scheme of maximum production of diesel oil,the yield of diesel oil was 80%,and the cetane number could be maintained above 58;under the scheme of maximum production of aviation kerosene,the yield of qualified aviation kerosene could reach 46%,and the cetane number of by-product diesel could be up to 79.
