Nine oil shale and mudstone samples from [K.sub.2][qn.sup.1] in the southeastern Songlio Basin were selected for maceral

In addition, maximum vitrinite reflectance measurements and proximate, ultimate, and maceral
composition and coal ash composition analyses were performed following the GB/T 6948-2008, GB/T 2122008, GB/T 476-2001, GB/T 8899-1998 and GB/T 1574-2007 standard procedures, respectively.

The enrichment of coal provides an opportunity for the separation of coals and their maceral
composition due to the difference of densities .
Over recent decades, extensive theoretical and experimental research has been performed on gas adsorption by coal, most of which focused on the effects of physical and chemical properties of coal (such as maceral
and mineral composition , pore structure , and functional group content ) and experimental conditions (such as temperature , pressure , adsorbates , and moisture ).

composition on ignition and char burnout of pulverized coal," Fuel Processing Technology, vol.
The R tests were carried out using hole-rock maceral
analysis (SY/T 6414-1999, Chinese petroleum and natural gas industry standard), and at least 800 points were tested.
Most of the difficulties associated with coal utilization arise from inorganic mineral matter rather than maceral
