The purpose of coal conversion is the production of alternative fuels, including motor fuels, or the generation of a range of chemicals from coal by process routes, such as gasification, direct and indirect liquefaction, hydropyrolysis, and plasmapyrolysis. The application of these techniques is essential if the large reserves of coal are to be ...

Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more ...

With more heat, time, and pressure, the kerogen underwent a process called catagenesis, and transformed into hydrocarbons. Hydrocarbons are simply chemicals made up of hydrogen and carbon. Different combinations of heat and pressure can create different forms of hydrocarbons. Some other examples are coal, peat, and natural gas.

The process, which essentially is cracking in reverse, takes place in a series of large, horizontal vessels and tall, skinny towers. Reforming uses heat, moderate pressure, and catalysts to turn naphtha, a light, relatively lowvalue fraction, into highoctane gasoline components. Treatment. The finishing touches occur during the final treatment.

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.
