摘要
本文从超临界萃取原理、溶剂体系、萃取过程中的化学反应、萃取动力学、萃取产物的结构分析，以及影响萃取过程的主要因素等方面，系统地论述了当前煤超临界萃取研究的发展状况。
Supercritical gas extraction (SGE)of coal has been investigated deeply under various conditions.In this article,SGE was discussed in terms of the principle of extraction,the solvent systems,the chemical reactions taking place during extraction,the reaction kinetics,the structure analyses of the extracts and other main factors effecting the extraction processes.
