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 ...

The Bergius process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of highvolatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913. In 1931 Bergius was awarded the Nobel Prize in Chemistry for his development of highpressure chemistry. [1] Process

In 192529, Bureau scientists studied ways to squeeze oil from shale. In 192830 and 193744, the Bureau had experimented with coal hydrogenation, the fundamental process that Germany's Frederick Bergius had first discovered in 1921. Read more about the origins of the Bergius process.

However, the Bergius process DCL plants were chosen in 1939 when Germany expanded production during the Second World War, because these were further developed and could be more readily scaled to larger size, eventually processing up to 350 tons of coal and yielding 250,000 L of gasoline per day.

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.

Under high pressures and temperatures, a slurry of crushed coal and processderived oil directly reacts with hydrogen in direct liquefaction (Yan, 1986). It is based on the Bergiusprocess, in which coal is dissolved under high temperatures and pressure (Klerk, 2014).

The use of nascent hydrogen from hydriodic acid at 270°C gave 60% of the weight of the coal as oil. A fundamental improvement is achieved by the division of the hydrogenation process into two stages—namely, (1) liquidphase hydrogenation and (2) vaporphase hydrogenation. This twostage process for the hydrogenation of tar proves useful also ...

In the early 20th century, German researcher Friedrich Bergius developed a process to directly liquefy coal under high temperature and pressure (coal begins to dissolve above 250 degrees centigrade), and then "crack" the coal molecules into smaller molecules using hydrogen. 2 Bergius termed the process "coal hydrogenation,"

Developed by NCB at Coal Research Establishment, Stoke Orchard, UK, the process involves extraction by a solvent like toluene above its supercritical temperature and pressure. The extract is separated from the solvent and hydrocracked to produce liquid distillates. It gives an yield of 14% gasoline and 35% diesel.
