甲醇制芳烃工艺经济性分析

Economic analysis of methanol to aromatics process

基于我国“多煤少油”的现状,开展以煤基甲醇为原料制备芳烃(MTA)具有重要的研究意义。但是在低油价的形势下,MTA工艺的经济性相比石油制芳烃较差,不利于大规模工艺化生产。简单介绍了MTA的反应历程,并对其经济性进行了重点分析,有助于今后对MTA全流程工艺进行优化。

Based on the current situation of"more coal and less oil"in China,it is of great significance to study the preparation of aromatics(MTA)from coal-based methanol.However,under the situation of low oil price,the economy of MTA process is worse than that of petroleum to aromatics,which is not conducive to large-scale process production.The reaction process of MTA was briefly introduced,and its economy was mainly analyzed,which is helpful to optimize the whole process of MTA in the future.
