  • SNG | Gasification | Haldor Topsoe

    In the gasification unit, a carbon-containing material such as coal, petcoke or biomass reacts with a controlled amount of oxygen and steam at high temperature. This results in a raw synthesis gas consisting of CO, CO 2, H 2, H 2 O, H 2 S, COS, CH 4 and other compounds (incl. tars, slag and dust).

    This report presents the results of the research and development conducted on an Advanced Hydrogasification Process (AHP) conceived and developed by Arizona Public Service Company (APS) under U.S. Department of Energy (DOE) contract: DE-FC26-06NT42759 for Substitute Natural Gas (SNG) production from western coal.

  • Coal to Substitute Natural Gas

    COAL TO SUBSTITUTE NATURAL GAS (November 2010) What initially prompted the production of substitute natural gas (SNG) in the United States was the concern over volatile natural gas prices, declining gas production and domestic energy security. These factors sparked a revival of interest in developing reliable domestic sources that

  • Coal gasification - Wikipedia

    Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)–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 ...

  • How Gasification-Carbon Capture Works - Coal Transition ...

    Approximately 90% of the carbon dioxide created in the substitute natural gas process can be captured and stored. This results in a net 50% or more reduction in CO2 emissions compared to the original coal when the substitute natural gas is burned in a conventional natural gas power plant.

  • Syngas - Wikipedia

    Syngas, or synthesis gas, is a fuel gas mixture consisting primarily of hydrogen, carbon monoxide, and very often some carbon dioxide.The name comes from its use as intermediates in creating synthetic natural gas (SNG) and for producing ammonia or methanol.Syngas is usually a product of coal gasification and the main application is electricity generation.
