对石脑油型加氢裂化反应过程影响因素进行了研究，结果表明：转化深度的提高有利于增产重石脑油，但选择性和芳烃潜含量有所下降，氢分压的变化对重石脑油收率、选择性和芳烃潜含量影响较小，循环重石脑油以上馏分，可获得更高的重石脑油选择性且重石脑油收率可达68％以上。根据中国石化石油化工科学研究院石脑油型加氢裂化技术试验结果，设计了1500 kt/a 加氢裂化装置，采用尾油馏分循环生产石脑油和柴油馏分方案，可为炼油厂每年提供700 kt 以上的重整装置原料，满足重整装置生产的需求。

Hydrocracking is an important technology for maximizing reforming feedstock naphtha production. The influence factors of the reaction process were studied. The results show that the heavy naphtha yield is increased,but the heavy naphtha selectivity and potential aromatics content are reduced with increase of conversion rate. While the changes of hydrogen partial pressure within the test range have little impact on those features. The heavy naphtha selectivity and potential aromatics content are improved by cycling the unconverted oil. The yield of heavy naphtha reaches 68% by this operation mode. Based on the test results,a 1 500 kt/a hydrocracking unit was designed where the recycling mode for increasing naphtha and diesel was applied. The technology could meet the demands of reforming feedstock and clean diesel.
