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).
