催化重组方法;CATALYTIC REFORMING PROCESS

摘要

本发明系关于一种自包括石蜡及环烷之石脑油馏分(1)开始的用于产生具有95以上之辛烷值之汽油之方法，该方法包括以下步骤：a)将该石脑油馏分传送至第一催化重组单元(2)以便将该等石蜡及/或环烷之至少一部分转化成芳香族化合物并产生氢气；b)自该第一催化重组单元(2)抽取第一流出物(3)及氢气流；c)将该第一流出物(3)传送至分离单元(5)以便将含有直链石蜡的轻烃馏分(6)与含有未经转化石蜡及/或环烷之重烃馏分(7)分离；d)将该轻烃馏分传送至异构化单元(11)以便产生异构油(12)；e)将该重烃馏分传送至第二催化重组单元(8)；f)自该第二催化重组单元抽取含有芳香族化合物的重组油(10)。; b) withdrawing a first effluent (3) and a stream of hydrogen from the first catalytic reforming unit (2); c) sending the first effluent (3) to a separation unit (5) so as to separate a light hydrocarbon cut (6) containing straight chain paraffins and a heavy hydrocarbon cut (7) containing unconverted paraffins and/or naphthenes; d) sending the light hydrocarbon cut to an isomerization unit (11) in order to produce an isomerate (12); e) sending the heavy hydrocarbon cut to a second catalytic reforming unit (8); f) withdrawing a reformate (10) containing aromatic compounds from the second catalytic reforming unit.
