Coal liquefaction Simple English Wikipedia, the free encyclopedia

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.

Mining Coal. Coal is extracted by two principal methods, of which there are many variants: surface mining or subsurface mining. Surface mining uses large machines to remove the soil and layers of rock known as overburden to expose coal seams that are close to the Earth's surface (figure (PageIndex{4})).Strip mining is a type of surface mining in which overburden is sequentially removed ...

The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of highvolatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913. In 1931 Bergius was awarded the Nobel Prize in Chemistry for his development of highpressure chemistry.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
