Coal hydrogenation converts different varieties of coal into synthetic petroleum or oil by reacting coal with hydrogen gas at high pressure and high temperature. Bergius was the first to hydrogenate coal successfully and to foresee the commercial development of a synthetic liquid fuel in dustry. He believed that coal hydrogenation provided ...

Bergius did not investigate the influence of different catalysts on the hydrogenation reaction, and his process was a onestage operation; the hydrogenation of coal and the splitting of the products formed took place in one step. This procedure resulted in a smaller amount of the reaction products splitting into gasolinesize molecules.

100th Anniversary: Bergius Process. The Bergius process is a method for the production of liquid hydrocarbons, such as gasoline, diesel, and jet fuel, for use as synthetic fuel. This method was developed by Friedrich Bergius and patented in 1913. The process involves the hydroliquefication of brown coal, also known as lignite, into crude oil.
