摘　　要： 为扩大喷气燃料资源,满足民航对喷气燃料的需求,对焦化全馏分油加氢后的喷气燃料馏分性质进行了分析,发现碱性氮的存在是影响焦化全馏分加氢后喷气燃料馏分颜色安定性的主要因素。在实验室里采用RA01和RB01特种吸附剂的非加氢组合工艺对焦化全馏分加氢后喷气燃料进行精制试验,结果表明,喷气燃料馏分经过非加氢精制后,颜色提高到+29,其它性质未见明显改变,所有性质均符合GB6537—943号喷气燃料标准。使用性能评定试验结果表明,焦化全馏分加氢后喷气燃料经过非加氢精制后其组成、橡胶相溶性、动态氧化热安定性、润滑性均可达到使用要求。 In order to meet the increasing demand of 3# jet fuel served i n civil aviation, further treatment is needed to improve the color stability of th e hydrofining coker distillate. It was found through the analysis that the main factor caused the color unstable was the existence of basic nitrogen. Special ad sorbents, RA-01 and RB-01, were applied for treating the hydrofining coker dis tillate in the laboratory. The treating results showed that the class of color i mproved to +29 without obvious changes on other properties, all the properties m et the GB6537-94 standard. The evaluation of the service performance indicated t hat the indexes of composition, solubility with rubber, dynamic thermal-oxidati ve stability and lubricity all met the service requirements.
