If coal is heated with hydrogen at high temperature and high pressure, it is converted into gasoline. This process of preparation of liquid fuel from solid coal is called hydrogenation of coal. Two methods are available for hydrogenation of coal. They are Bergius process (direct method): Fischer Tropsch Method (indirect method) Bergius process:

As shown in Fig., coal from hydrogenation yields phenols, BTXaromatics, olefines and higher nuclei aromatics, premium gasoline and diesel fuel (Jüntgen, 1982a).The first step of coaloil processing is distillation by which light oil, middle oil and heavy oil are produced. The processing of these fractions utilizes techniques well known in mineral oil refining.

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.
