This product formed the binder for briquetting non-caking coal or coal dust. The briquettes were formed, then subjected to a Low Temperature Carbonization (LTC) process. The tar obtained from this process was refined by a pressure distillation in which more volatile compounds were recovered and higher-molecular weight compounds were split up before becoming volatilized. The residue produced was aCharFuel® Coal Refining Process – Carbon Fuels,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.Carbon Fuels – CharFuel® Coal Refining Process,The CharFuel ® Coal Refining Process refines raw coal in conceptually the same manner as crude oil is refined to cleanly and economically produce high-value liquid fuels, petrochemicals, and clean power plant feedstock. The CharFuel ® Coal Refining Process is not a supplemental source of alternative energy, but is a predominant source.Refined coal - Wikipedia,Refined coal is the product of the application of a coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite(brown) coals and raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned. The goals of pre-combustion coal-upgrading technologies are to increase efficiency and reduce emissions when coal is burned. Dependin…METHOD FOR REFINING COAL - BRUSO BRUCE L,Basic Process. The coal refining process of this application, as defined in claim 1, uses ammonium hydroxide (NH 4 OH), more commonly known as aqueous ammonia, as a solvent and as an oxidizing agent for reducing sulfur contaminant in coal. While ammonia has been suggested as a component of an oxidation reagent, as in the Bender patents described above, the process of this invention is carriedRefining the process that refines the coal (Journal,,First operated in 1973 to refine a sulfur-free solid fuel from coal, the Electric Power Research Institute's small pilot plant at Wilsonville, Alabama, is now a focal point for research and development in coal liquefaction.

Policies are stricter by the Indian government who set up these policies for coal refinement. In this article we discuss some of the coal washing process that is not only safe and secure, but follows all the principles of coal mining and workers safety. Stockpiling process involves running the coal,
