Friedrich Bergius, also a German chemist, invented direct coal liquefaction (DCL) as a way to convert lignite into synthetic oil in 1913. Coal liquefaction was an important part of Adolf Hitler 's four-year plan of 1936, and became an integral part of German industry during World War II . [ 4 ]

One of the main methods of direct conversion of coal to liquids by hydrogenation process is the Bergius process. [33] In this process, coal is liquefied by heating in the presence of hydrogen gas (hydrogenation). Dry coal is mixed with heavy oil recycled from the process. Catalysts are typically added to the mixture.

Known as the Eastman Integrated Coal Gasification facility, it first opened in 1983 and is designed to process syngas from the gasification of Southwest Virginia and Eastern Kentucky coal, using Texaco gasifiers (now GE gasifier technology [15]). The intermediate products of syngas conversion are methanol and CO; these are further converted ...
Some Navy officials showed outstanding support for the initiative. In 1914, Admiral John Jellicoe wrote to Fisher: It [oil fuel] is also most a necessity for these vessels because of the great difficulty that they experience in our present battle cruisers of getting coal to the furnaces sufficiently rapidly to keep their full speed after they have reduced coal on board to from 50 to 60% of its ...
Carbochemistry is the branch of chemistry that studies the transformation of coal (bituminous coal, coal tar, anthracite, lignite, graphite, and charcoal) into useful products and raw materials. [1] The processes that are used in carbochemistry include degasification processes such as carbonization and coking , gasification processes, and ...
