    • A process for producing sec-butylbenzene comprises feeding reactants comprising benzene and a Colefin to a distillation column reactor having a first reaction zone containing an alkylation catalyst and a second distillation zone, which is located below said first reaction zone and which is substantially free of alkylation catalyst, wherein the ratio of the number of distillation stages in said first reaction zone to the number of distillation stages in said second distillation zone is less than 1 : 1. Concurrently in the distillation column reactor, the reactants are contacted with the alkylation catalyst in the first reaction zone under conditions such that the Colefin reacts with the benzene to produce sec-butylbenzene and the sec-butylbenzene is fractionated from the unreacted Colefin. The sec-butylbenzene thereby passes as a liquid phase stream from the first reaction zone to the second distillation zone and the liquid phase stream is withdrawn from the distillation column reactor as bottoms.
    • 一种生产仲丁基苯的方法包括将含有苯和烯烃的反应物进料到蒸馏塔反应器中,所述蒸馏塔反应器具有含有烷基化催化剂的第一反应区和位于所述第一反应区下面且基本上不含烷基化的第二蒸馏区 催化剂,其中所述第一反应区中的蒸馏级数与所述第二蒸馏区中的蒸馏级数之比小于1:1。同时在蒸馏塔反应器中,使反应物与烷基化催化剂接触 在第一反应区,使烯烃与苯反应产生仲丁基苯,仲丁基苯由未反应的烯属烃分馏。 因此,仲丁基苯以液相流从第一反应区流向第二蒸馏区,液相物流作为底部从蒸馏塔反应器中排出。

    • A process for the production of alkylbenzene includes the steps of introducing benzene and an olefin feed into a first alkylation reaction zone in the presence of a first alkylation catalyst under first alkylation reaction conditions to produce alkylbenzene and a vapor containing unconverted olefin; absorbing the unconverted olefin into an aromatic stream containing benzene and alkylbenzene; and, introducing the aromatic stream containing absorbed olefin into a second alkylation reaction zone containing a second alkylation catalyst under second alkylation reaction conditions to convert the absorbed olefin and at least some of the benzene of the aromatic stream to alkylbenzene. The process is particularly advantageous for the alkylation of benzene with ethylene to produce ethylbenzene. About 99.9 % conversion of ethylene is achieved overall, with a substantial reduction in the required catalyst.
    • 制备烷基苯的方法包括以下步骤:在第一烷基化反应条件下,在第一烷基化催化剂存在下,将苯和烯烃进料引入第一烷基化反应区,以产生烷基苯和含有未转化烯烃的蒸气; 将未转化的烯烃吸收到含有苯和烷基苯的芳族物流中; 并且在第二烷基化反应条件下将含有吸收的烯烃的芳族物流引入含有第二烷基化催化剂的第二烷基化反应区,以将吸收的烯烃和至少一部分芳族物流的苯转化为烷基苯。 该方法对于用乙烯烷基化苯以产生乙苯特别有利。 总共实现了约99.9%的乙烯转化率,所需的催化剂显着降低。
