对二甲苯生产新技术分析

Analysis of P-xylene Production New Technologies

近年来,对二甲苯市场缺口不断增大,而传统的对二甲苯生产路线存在原料利用率低、对二甲苯分离能耗大等问题。以甲苯甲醇/苯和甲醇为原料的对二甲苯生产新路线,可以有效的提高对二甲苯选择性。如能尽早实现工业化,对增强我国PX竞争力将会有很大帮助。

In recent years, the p- xylene（PX） market gap is growing, traditional production line for PX being problems such as： low utilization of raw material, PX separation energy consumption. The new px synthesis process which took benzene and methanol or toluene and methanol as raw material, the selective ofpx can be effectively improved. If industrialization can be achieved as soon as possible, can enhance px＇s competitiveness.
