It has also been used to convert coal and heavy oil into hydrogen for the production of ammonia and ureabased fertilizer. As a process, it continues to be used in South Africa as a source for liquid fuels (gasification followed by FischerTropsch synthesis). Gasification typically takes place at temperatures from °C.

The term coal gasification refers to any process by which coal is converted into some gaseous form that can then be burned as a fuel. Coal gasification technology was relatively well known before World War II, but it fell out of favor after the war because of the low cost of oil and natural gas . Beginning in the 1970s, utilities showed renewed ...

Coal gasification is a process by which coal is converted into a fuel gas rich in hydrogen and carbon monoxide. The process was first developed in about 1780 and was widely commercialized by the early 1900s. Before natural gas became widely available in the 1940s, many North American and European cities used coal gas as a heating and lighting fuel.
