Gasification of biomass is a thermochemical process that converts biomass directly into fuel gases of a mixture of carbon monoxide, hydrogen, methane, and carbon dioxide, etc. There are two types of gasification: common gasification of biomass is a partial oxidization process by air or pure oxygen. Another type of gasification in a supercritical aqueous environment is called HTG; biomass is ...

Coal gasification technologies have been known for more than 100 years. Gasification is a thermochemical process in which the fuel, coal in this case, is converted into synthesis gas composed of carbon monoxide and hydrogen. There are number of papers deal with the lignite cogasification with biomass/biowaste or Solid Recovered Fuel.

Library. Fundamentals. Gasification is a partial oxidation process. The term partial oxidation is a relative term which simply means that less oxygen is used in gasification than would be required for combustion (, burning or complete oxidation) of the same amount of fuel. Gasification typically uses only 25 to 40 percent of the ...

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.

Coal gasification technology is an effective means to achieve clean and efficient utilization of coal. Coal gasification slag is generated in the process of coal gasification owing to the existence of minerals in the coal, particularly the incomplete reaction of the organic carbon elements in the coal.
