    Coal Gasification The Canadian Encyclopedia

    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.
