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".

Abstract. Coal gasification is an important industrial process for converting raw coal into more useful and cleaner carbon feedstocks for use in power generation and as precursors for other transformations. Coal gasification involves complex heterogeneous physical and chemical changes that occur between coal and gaseous reactants.

A 72h ex situ hard coal gasification test in one large block of coal was carried out. The gasifying agent was oxygen with a constant flow rate of m3/h. The surroundings of coal were simulated with wet sand with 11% moisture content. A 2cm interlayer of siderite was placed in the horizontal cut of the coal block. As a result of this process, gas with an average flow rate of m3/h was ...

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 ...
