The samples were separated into vitrinite, sporinite, and resinite. Geo-chemical and pyrolysis methods were used to analyse three maceral groups and two seam samples. The results indicate that the resinite and sporinite groups have higher extract yields, S1, S2, HI values, and pyrolysis compounds. These differences may shed light on the usage of the Huangxian lignite. Seam 2 pro- duces more gas and oil than seam 4 does because seam 2 contains more resinite and sporinite macerals.展开更多
