In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), 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 gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.

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 theoretical oxidant (either pure oxygen or air) to generate enough heat to gasify ...

The gasification of biomass and municipal solid waste (MSW) differ in many ways from the gasification of coal, petcoke, or conversion of natural gas to syngas. This section will discuss these differences, the technology used to gasify biomass and MSW, and give a brief overview of some operating plants. Characteristics of Biomass and MSW.

Underground Coal Gasification (UCG) takes advantage of the same chemical reactions of coal to produce product gases, as those occurring in conventional gasifier reactors. The main difference is that in UCG the underground coal seam itself becomes the reactor, so that the gasification of the coal takes place underground instead of in a manufactured gasification vessel at the Obviously ...

Coal gasification is the method of transforming coal and water into syngas, which is a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane (CH4), as well as water vapour (H2O). Coal gas, commonly known as "town gas", was once produced by gasifying coal.

type of gasifier has often been used to gasify coal. What Is the Gasification Medium? The simplest gasification process uses air as the reactive agent (as shown in Figure 4 on page 6), which converts the excess char into a low energy syngas (142209 Btu/ft. 3) consisting mainly of hydrogen and carbon monoxide diluted with nitrogen from the air.

Gasification is the conversion of a solid or a liquid into a gas. In a broad sense it includes evaporation by heating, although the term is reserved for processes involving chemical change. The primary raw material for gasification is normally considered to be coal, although the use of oil shale for gasification has been discussed.
