WebThe gasification rate of a coal is governed by its structure, with reaction gases penetrating particles and attacking carbon atoms and the resultant gases diffusing through the solid structure (Feng and Bhatia, 2003). Reactions occur only on the reactive surface area, and not all micropores may be reactive. WebGasification processes use one or a combination of three reactant gases: oxygen (O 2 ), steam (H 2 O), and hydrogen (H 2 ). The heat required for the endothermic gasification reactions is suppled by the exothermic combustion reactions between the coal and oxygen.
