Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Coal liquefaction is the process of converting solid coal into liquid fuel. This process has been developed as a means to utilize coal resources that are otherwise difficult to access and transport. The resulting liquid fuel, called synthetic crude oil, can be refined into a variety of fuels, including diesel, gasoline, and aviation fuel.
