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 ...

WhatsApp: +86 18203695377If 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:
WhatsApp: +86 18203695377Hydrogenation of both coal and coal tar produces a wide variety of products, depending on the method of operation. Aviation gasoline, motor gasoline, diesel oil, fuel oil, illuminating oils, and lubricating oils have been made from coal and coal tar. Byproducts include gaseous hydrocarbons, sulfur, phenols, wax, and aromatic hydrocarbons.
WhatsApp: +86 18203695377In the Bergius process, liquid hydrocarbons are produced through hydrogenation of coal dust at high temperature and pressure. In the FT reaction, a mixture of carbon monoxide and hydrogen is converted into liquid hydrocarbon at elevated temperature and normal or elevated pressure in the presence of a catalyst of magnetic iron oxide.
WhatsApp: +86 18203695377The first commercially available liquefaction process was the Bergius process, developed in Germany as early as 1911 but brought to commercial scale during World War I.
