加氢裂化反应工艺参数对喷气燃料馏分收率和性质的影响规律研究

为通过调整加氢裂化装置反应条件来控制喷气馏分燃料收率和质量，以中间基蜡油为原料在双剂串联一次通过流程下考察了裂化反应温度、氢分压、体积空速和氢油比对喷气燃料馏分收率和性质的影响。结果表明：不同反应条件下蜡油原料中大于350℃馏分的转化率影响喷气燃料馏分收率，蜡油原料中大于350℃馏分转化率越高，喷气燃料馏分收率越高；不同氢分压下，喷气燃料馏分的芳烃加氢饱和程度影响其烟点，其他反应条件参数对烟点的影响均和蜡油原料的转化深度相关。

EFFECT OF HYDROCRACKING REACTION PARAMETERS ON YIELD AND PROPERTIES OF JET FUEL FRACTION

In order to satisfy the quality demand of jet fuel fraction from hydrocracking unit by adjusting reaction conditions，the effect of reaction parameters of hydrocracking temperature，hydrogen pressure，volume velocity and volume ratio of hydrogen to oil on jet fuel yield and properties were tested using intermediate-base gas oil as feedstocks in single stage once through mode in a hydrocracking device packed with two catalysts in series. The result showed that the jet fuel fraction yield was affected by conversion rate of gas oil under different reaction conditions, the higher the conversion rate of wax oil above 350℃, the higher the jet fuel yield, and that at the same conversion ratio under different hydrogen pressure, the jet fuel fraction smoke point was effected by aromatic saturation extent，while the effects of other reaction conditions on the smoke point were all related to the conversion depth of gas oil feedstock.
