Coal Refining Process. Coal and crude oil are both hydrocarbons. They can be refined in the same manner. Like crude oil, coal produces transportation, heating fuels, electricity generation feedstock (char), and petrochemicals. Refining coal using the CharFuel ® Coal Refining Process removes pollutants from char prior to combustion or gasification.

2015-10-2 coal refining process involves thermal hydrocracking which results in "hydrodisproportionation" (rearrangement of hydrogen within the coal molecule) to produce a slate of co-products, just as is done with crude oil in petroleum refining. See Figure I. In the Charfuel® process, pulverized coal is rapidly heated in a reducing at-mosphere in the ...

2020-2-1 Such wastes are called filter cakes (FC). FC is a mixture of fine coal (particle size about 100 μm) with water (mass fraction about 50%). Such combustible waste is a by-product of coal processing that can be used in thermal power engineering as fuel (Nyashina et al., 2017, 2018a). At coal washing plants, FC is usually stockpiled at open sites.
