阅读说明：本技术 经由甲基化转化苯和/或甲苯的方法 (Method for converting benzene and/or toluene via methylation ) 是由 S·M·瓦士布恩 H·蒋 陈诞仁 于 2020-03-18 设计创作，主要内容包括：本公开提供经由用甲醇/二甲基醚甲基化,来将苯/甲苯转化以生产例如对二甲苯的改进的方法。在一种实施方案中,方法包括将甲基化剂进料与芳烃进料在增加的压力下在甲基化反应器中在甲基化催化剂存在下接触。使用所述甲基化反应器中增加的压力可以实现甲基化催化剂失活的减少。(The present disclosure provides an improved process for the conversion of benzene/toluene to produce, for example, para-xylene via methylation with methanol/dimethyl ether. In one embodiment, the process comprises contacting a methylating agent feed with an aromatic hydrocarbon feed at an increased pressure in a methylation reactor in the presence of a methylation catalyst. Reduced methylation catalyst deactivation can be achieved using increased pressure in the methylation reactor.)
