摘　　要：石脑油芳构化改质工艺技术(GAP),是利用择形分子筛催化剂将石脑油中烷烃转化为芳烃来提高汽油辛烷值的新的工艺技术。GAP工艺技术总液体收率高达93%～96%,其中高辛烷值汽油组分收率65%～75%,液化石油气收率20%～30%;汽油辛烷值(RON)根据需要可在86～93之间灵活调节。根据各个厂家的不同情况,可以选择汽油辛烷值高的GAP-I和GAP-II工艺方案,也可以选择总液体收率高的GAP-III工艺方案。该工艺技术为炼油厂生产清洁汽油开辟了一条新途径。Naphtha aromatic upgrading process(GAP)is new technology of improving gasoline octane number. The technology is an effective method of improving gasoline octane number for refineries. The liquid product yield was 93%~96%, in the process, high octane number gasoline yield 65%~75%,liquid petroleum gas yield 20%~30%. The gasoline octane number (RON) may be change from 86 to 93 according to requirement of refineries. According to specific conditions, we may choice GAP-I and GAP-II for producing high octane number gasoline and we also may choice GAP-III for getting more liquid yield. The technology opens a new route for refineries producting clean gasoline.
