由煤制取芳烃化合物的研究进展

Advances in the preparation of aromatics from coal

综述了国内外由煤制取芳烃化合物的三种思路:一是通过将煤直接进行液化获取,或者先将煤液化再从产物中获得芳烃化合物;二是先对煤进行溶剂抽提,然后对产物分类加工制取芳烃化合物;三是将煤进行氧化处理来获得高价值的芳烃化合物。分析了由煤制取芳烃化合物的所面临的产物分离困难、污染环境等问题,并指出了今后需要在分离工艺和催化剂以及如何实现煤的定向转化等方面进行重点研究。

In this paper,three methods for producing aromatics from coal have been reviewed.It can be obtained from coal by direct liquefaction or the separation of the aromatic compounds from coal liquefaction products in which coal is extracted by several kinds of solvents first,and then aromatic compounds are obtained through product classified processing.The high value aromatic compounds can be obtained by the oxidation of coal.And the difficulties in the preparation of aromatics from the coal,are analyzed,regarding product separation and environmental pollution.With the consideration of separation processes and catalysts,how to implement the coal-directional conversion should be focused on in the future.
