    • An integrated process is described for the preparation of ethylbenzene and cumene, comprising the following stages: (a) contacting benzene and an olefin chosen from ethylene and propylene, in the presence of a catalyst containing one or more zeolites, (b) contacting the mixture resulting from the previous stage with an olefin chosen from ethylene and propylene, said olefin being different from that used in stage (a), and possibly with benzene, in the presence of a catalyst containing one or more zeolites, (c) subjecting the mixture resulting from stage (b) to separation in order to isolate at least one fraction containing ethylbenzene and a fraction containing cumene. A preferred aspect is that the olefin used in stage (a) is ethylene and the olefin used in stage (b) is propylene. In stage (c) a fraction containing polyalkylbenzenes to be sent to a transalkylation step for the recovery of further ethylbenzene and cumene, can also be isolated.
    • 描述了用于制备乙苯和异丙基苯的综合方法,包括以下阶段:(a)在含有一种或多种沸石的催化剂存在下,使苯和选自乙烯和丙烯的烯烃接触,(b)使混合物 由前述阶段产生的烯烃选自乙烯和丙烯,所述烯烃与阶段(a)中所用的烯烃不同,并且在含有一种或多种沸石的催化剂存在下,可能与苯不同,(c)使混合物 从阶段(b)到分离,以便分离至少一个含有乙苯的馏分和含有异丙基苯的馏分。 优选的方面是(a)阶段中使用的烯烃是乙烯,(b)阶段中使用的烯烃是丙烯。 在阶段(c)中,还可以分离含有待转运到烷基转移步骤以用于回收另外的乙苯和异丙基苯的多烷基苯的级分。

    • A process for reducing benzene content in a reformate stream, including: fractionating a full range reformate comprising benzene, C 7 to C 9 monoalkyl aromatics, and C 1O+ polyalkyl aromatics into at least three fractions including a light reformate fraction comprising the benzene; a medium reformate fraction comprising the C 7 to C 9 monoalkyl aromatics; and a heavy reformate fraction comprising the C 10+ polyalkyl aromatics; feeding the light reformate fraction, the heavy reformate fraction and a transalkylation catalyst to a transalkylation reaction zone; contacting the light fraction and the heavy fraction in presence of the transalkylation catalyst in the transalkylation reaction zone to react at least a portion of the benzene with C 1O+ polyalkyl aromatics to form monoalkyl aromatics; separating an effluent from the transalkylation reaction zone to form a catalyst fraction and a liquid fraction comprising the monoalkyl aromatics.
    • 一种用于还原重整产物流中苯含量的方法,包括:将包含苯,C 7至C 9单烷基芳烃和C 10+多烷基芳族化合物的全范围重整产物分馏成至少三个馏分,包括包含苯的轻重油馏分; 包含C7-C9单烷基芳族化合物的中等重整油馏分; 和包含C10 +多烷基芳烃的重质重质馏分; 将轻重整油馏分,重质量重馏分和烷基转移催化剂加入烷基转移反应区; 在烷基转移反应区中在烷基转移催化剂存在下使轻馏分和重馏分接触,使至少一部分苯与C 1-10烷基芳族化合物反应形成单烷基芳族化合物; 分离来自烷基转移反应区的流出物以形成催化剂级分和包含单烷基芳族化合物的液体级分。
