| 摘 要： | 本文利用ＣＯ／Ｈ＿２Ｏ体系，对我国三种煤进行了亚临界─超临界流体萃取的研究。鉴于可保煤有较高的反应活性，故进一步考察了过程参数对其萃取率的影响，寻找了较好的工艺条件，在此条件下萃取率可达８８％左右，油收率可达６０％。研究了萃取物的基本性质，探讨了残煤的利用途径。

| Abstract: | In this study,three types of chinese coal were subjected to sub-and supercritical fluid extraction in catalyzed CO/H_2O system. Due to the superior reactivity of kebao lignite,it is conducted to examine the effects of process parameters and to chcose better technical condi-tions in which the yield of extracts is about 88%and the yield of oil is 60%. The basic properties of extract and utilization of residual lignite were also investigated. |
