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一定辛烷值之汽油及用于联合产生芳香基料之方法，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(4)；c)将该第一流出物(3)传送至芳香烃分离单元(5)以便将第一芳香烃馏分与含有未经转化环烷及/或石蜡之萃余液(7)分离；d)将该萃余液(7)传送至第二催化重组单元(9)以便将该等未经转化环烷及/或石蜡转化成芳香族化合物并产生氢气；e)自该第二催化重组单元(9)抽取含有芳香族化合物之重组油(11)及氢气流(10)。; b) withdrawing a first effluent (3) and a stream of hydrogen (4) from the first catalytic reforming unit (2); c) sending the first effluent (3) to an aromatics separation unit (5) so as to separate a first aromatic cut and a raffinate (7) containing unconverted naphthenes and/or paraffins; d) sending the raffinate (7) to a second catalytic reforming unit (9) so as to convert the unconverted naphthenes and/or paraffins into aromatic compounds and to produce hydrogen; e) withdrawing a reformate (11) containing aromatic compounds and a stream of hydrogen (10) from the second catalytic reforming unit (9).
