WEBCoal liquefaction is now recognized as a process of immense future significance for the production of alternative liquid fuels and chemical feedstocks. It is a process with a long technical history, and it is important for those currently working in the field to have an opportunity of seeing at least the alytic component from an historical ...
WEBSo, coal is a hydrogen deficient compound. If coal is heated with hydrogen to high temperature under high pressure, it is converted to gasoline. The preparation of liquid fuels from solid coal is called hydrogenation of coal (or) synthetic petrol. An important method, available for the hydrogenation of coal is Bergius process (or direct method).

WEBThe Bergius process is a method of production of liquid hydrocarbons by hydrogenation of highvolatile bituminous coal at high temperatures and pressure. The Karrick process is related to low temperature coal carbonization. It could be used to distil out synthetic fuelsunconventional oil and syngas.
WEBJan 1, 2008 · Direct coal liquefaction has long been recognized as a competition between hydrogenation to liquid products and destructive distillation that forms solids (Bergius, 1926). The former reaction represents the goal, whereas the latter leads us to consider the appliion of petrologic methods to help explain diminished productivity.
WEBThe process was perfected by C. Karrick, an oil shale technologist at the Bureau of Mines in the 1920s. LTC is a pyrolysis process that involves heating coal, shale, lignite, or any other carbonaceous material, including garbage) to about 800 o F. in the absence of oxygen. Oil is thus distilled from the material, rather than burning ...
WEBIn contrast to the FischerTropsch process, the Bergius hydrogenation process was performed at high temperatures (400600 [deg.] C) and pressures (200700 atmospheres). Although this process could employ any carbonaceous material, brown coal, abundant in Germany, was most often used.
WEBBergius shared the 1931 Nobel Prize in Chemistry with Carl Bosch for their contributions to the invention and development of chemical highpressure methods. He is credited with developing the Bergius Process, a method of producing liquid hydrocarbons for use as a synthetic fuel via hydrogenation of lignite coal at elevated temperature and pressure.
