  • Coal gasification Wikipedia

    OverviewHistoryProcessBy-productsCommercializationEnvironmental impactCoal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide, hydrogen, carbon dioxide, natural gas, and water vapour (H2O)–from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas". Coal gas is combustible and was used for municipal lighting, and heating, before the advent of large scale production of natural gas from oil wells. In current practice, large-scale coal gasification.
