aromatics

The process of toluene disproportion is an important technology of aromatics mutual conversion. The purpose is to convert the directly less used and relative surplus toluene, C9 aromatics and C10 aromatics into benzene and xylene which are widely used and relatively scarce.

甲苯歧化与烷基转移工艺是芳烃间相互转化的一种重要技术，目的是把直接用途较少、相对过剩的甲苯、碳九芳烃和碳十芳烃转化为用途较广、相对紧缺的苯和二甲苯。

The influences of temperature, WHSV and C 10 aromatics content in the feedstock on the catalytic properties of the β zeolite based HAT 097B catalyst in toluene disproportionation and C 9 aromatics transalkylation reactions were investigated.

研究了以β沸石为主体的HAT097B催化剂在催化甲苯和C9芳烃歧化与烷基转移反应中，反应空速、温度及原料中C10芳烃含量对反应性能的影响。

Meanwhile, the lack of naphtha raw materials and the obsoleteness of production facilities and equipment will also affect China's aromatics production capacity.

同时，石脑油原料不足以及装置工艺设备老化等因素也将影响国内芳烃产能的正常发挥。
