[0002] Coal gasification refers to the process in which solid fuels such as coal, coke, and semi-coke react with a gasifying agent under high temperature, normal pressure or pressurized conditions to convert them into gas products and a small amount of residue. The gasifying agent is mainly water vapor, air (or oxygen) or a mixture of them. The gasification reaction includes a series of homogeneous and heterogeneous chemical reactions. The resulting gas products have different compositions depending on the quality of the raw coal, the type of gasifying agent and the gasification process. They can be divided into air gas, semi-water gas, water gas, etc. The coal gasification process can be used to produce fuel gas as industrial kiln gas and city gas, and is also used to manufacture synthesis gas as a raw material for synthetic ammonia, synthetic methanol and synthetic liquid fuels.
