Coal gasification refers to the process of carbon oxide, hydrogen and methane produced from coal or semicoke with catalyst by heterogeneous reaction, it .
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air — a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived .
During the preparation of high strength gasificationcoke with lowrank coal blending, evolution of pyrolysis tar and gas is still unclear for situations where large amounts of lowrank coal are blended. Herein, the effect of lowrank coal blending on the distribution of coking products was thoroughly investigated and the mechanism of tar lightening was studied by simulating the .
