摘要
当前石油路线的芳烃生产面临资源短缺、建设难度大、成本高等困难,而丰富的煤炭资源与过剩的甲醇产能为甲醇芳构化提供了低成本原料。目前我国已掌握烷基化、固定床、流化床等多种形式的甲醇芳构化技术,部分技术在甲醇转化率、芳烃产率及对二甲苯选择性方面已经取得了成果,在研究与工业化方面走在了世界前列。分别对具有代表性的甲醇芳构化技术进行了概述,对各自技术的特点及技术先进性进行了简要分析,对产业发展提出建议。
Aromatics production by the oil line currently faces up with the difficulties such as resource shortage,difficult construction and high cost.However,abundant coal resources and methanol over-capacity provide a low cost raw material for methanol aromatization.At present,various forms of aromatization processes such as alkylation,fixed bed,fluidized bed,etc,have been mastered in China.Some of them have obtained the achievements in methanol conversion,aromatics yield and p-xylene selectivity,and leaps into the front ranks of the word in aspect of research and industrialization.The representative methanol aromatization techniques are summarized.Brief analysis on characteristics and the advancement of each technique are carried out,and the proposal for the industry development is put forward in the end.
