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 was used for heating and municipal lighting, before ...

Underground coal gasification (UCG) is an industrial process which converts coal into product gas. UCG is an in-situ gasification process, carried out in non-mined coal seams using injection of oxidants and steam. The product gas is brought to the surface through production wells drilled from the surface. The predominant product gases are methane, hydrogen, carbon monoxide and carbon dioxide.

Abstract. The Integrated Gasification Combined Cycle (IGCC) is a complex system, which couples technologies of gasification, gas cleanup, and a gas turbine (GT)/steam turbine combined cycle unit together for the generation of electricity in a more efficient, environmentally benign manner than conventional pulverized coal combustion plants.

The Coal Seam Gas (CSG) process is a natural gas extraction process from coal seams buried in the ground. In order to release the gas, the coal seams are de-pressurized by releasing large volumes of water. The water that is a by-product of the CSG production process often has difficult water chemistry, such as high silica and alkalinity.
