Coal utilization - Liquefaction | Britannica
Coal utilization - Coal utilization - Liquefaction: Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum. Therefore, conversion of coal into liquid fuels involves the addition of hydrogen.
Coal Liquefaction - an overview | ScienceDirect Topics
The direct liquefaction process ( Fig. 3) employs a coal ground to a fine powder, solvent, hydrogen, and catalyst employed at elevated pressures (1000–2500 psig) and temperatures (400–450°C). The solvent mixed with the coal forms a pumpable paste.
Coal liquefaction - Energy Education
Coal liquefaction is a process in which coal is converted into liquid fuels or petrochemicals. There are several processes used to accomplish this task, the two most common being the "indirect route" and the "direct route". The indirect route is composed of 2 steps: First, ...

Coal Liquefaction | Student Energy
In direct liquefaction, coal is exposed directly to hydrogen at high temperatures (450C) and high pressures (14000-20000kPa) for approximately one hour in the presence of a solvent that breaks down the hydrocarbon structure. Catalysts are used to improve rates of …
Coal Liquefaction | The Canadian Encyclopedia
Coal liquefaction is a process that converts coal from a solid state into liquid fuels, usually to provide substitutes for petroleum products. Coal liquefaction processes were first developed in the early part of the 20th century but later application was hindered by the relatively low price and wide availability of crude oil and natural gas.
Coal liquefaction | Britannica
Coal liquefaction, any process of turning coal into liquid products resembling crude oil.The two procedures that have been most extensively evaluated are carbonization—heating coal in the absence of air—and hydrogenation—causing coal to react with hydrogen at high pressures, usually in the presence of a catalyst.Coal hydrogenation was extensively used in Germany in World War II to ...

The International Maritime Solid Bulk Cargoes (IMSBC) Code describes coal as a natural, solid, combustible material consisting of amorphous carbon and hydrocarbons.Although coal is best known for its flammable and self-heating properties, certain coal cargoes may also be liable to liquefaction.
What is Coal Liquefaction? (with pictures)
Coal liquefaction is a process used to turn coal, a solid fuel, into a substitute for liquid fuels such as diesel and gasoline. This process has historically been used in countries without a secure supply of crude oil, such as Germany and South Africa.The technology used in the process is quite old, and was first implemented during the 19th century to provide gas for indoor lighting.

The nation stood as the largest producer of coal in the world, but history also remembers a darker side to the story. Steam shovels, tractors and equipment used in coal mining eroded the soil while railroads, industrial plants and homes polluted cities across the country.
Coal: its Role in Tomorrows Technology | ScienceDirect
Coal can also be liquefied and later fractionated to produce the equivalent of petroleum, a range of aromatics and on to tars. Liquefaction is the only route from coal to a liquid fuel for transport. Three gasifiers may be utilized for the liquefaction of coal—namely, Lurgi gasifier, Koppers-Totez method, and the Wrinkler process.
