| 摘 要： | 通过对阳泉煤、淮南煤及神木煤进行重液离心分离，得到了一系列对应于不同密度的分离物。对各密度段样品的热分析表明，煤中存在着对应于一定密度段的难燃组分，它们多是煤中的惰性组，部分矿物质及高矿化性的组分。

| Abstract: | Centrifugal separation with graVity liquid to Yangquan coal, Huainan coal and Shenmu coal was carried out in this paper A series of fraction with different density have been obtained It has been found that there exists amount of less combustible constituents in coals by means of thermogravimetrical analysis They always lie in the separation with specific density and are the enrichment of fusinite, minerite and highlymineralized composite |
