在反应性蒸馏塔内在烷基化和烷基转移的整合方法中通过选择改性酸固体催化剂获得用于冷却处理器的烷基芳烃合成润滑油的方法
Abstract:
本发明涉及获得烷基芳族化合物的方法，其中对于生产单烷基芳族化合物有更高选择性，所述方法通过在包含芳族和/或多芳族化合物的烷基化和烷基转移的整合方法中选择改性酸固体催化剂来选择性生产单烷基芳族化合物，以及再生(原位)用于这种方法的选择的酸固体催化剂。本发明的方法使得能够以高转化率、选择率和收率获得单烷基化化合物。
Abstract(English):

The present invention discloses a method for producing alkyl aromatic compounds with higher selectivity for the production of monoalkyl aromatic compounds, by selection of solid acid catalysts modified during an integrated process that includes alkylation and transalkylation of aromatic and/or polyaromatic compounds for the selective production of monoalkyl aromatic compounds, as well as the (in situ) regeneration of the solid acid catalysts selected to carry out this process. The method of the present invention allows monoalkylated compounds to be produced with high rates of conversion, selectivity and yield.
