"Coal liquefaction" is the process of converting coal into liquid hydrocarbon fuels. It has played an important part in human history. It was an integral part of the German industry during World War II and, after the war, Germany was forced to abandon its synthetic fuel production (Potsdam conference in 1945).

Answer: Liquefaction is the process of turning solid coal into liquid hydrocarbon fuel.. Explanation: Coal liquefaction is the process of transforming solid coal into liquid hydrocarbons. This approach is known as "Coal to X," with X referring to a variety of hydrocarbonbased elements. When saturated or partially saturated coal loses its strength and stiffness, it goes through the ...

obtained from gasification of coal to hydrocarbon liquids. Because the coal is first gasified before conversion to liquid fuels, the FischerTropsch (FT) process for CTL is known as a type of indirect coal liquefaction (ICL). ICL is a completely different approach from DCL for providing liquid fuels from coal. ICL processes first convert ...

The indirect route is composed of 2 steps: First, coal is gasified with steam and oxygen to produce a synthesis gas (syngas), which is then cleaned to rid of dust, tar, and acid gases. The second step reacts the synthesis gas with a catalyst in the FischerTropsch process, which converts the syngas into a range of hydrocarbon fuels such as ...

For coal and other solid fuel as feed, coal gasification process operating typically at the temperature range from 900 °C to 1600 °C can be selected according to the properties of the feed. Currently, there are several types of coal gasification technologies that can be selected using solid fuel as a feedstock.
