The purification process is the most critical in the process of comprehensive utilization of coke oven gas (electricity generation; production of hydrogen, methanol and natural gas). A reliable industrial coke oven gas purification process based on temperature swing adsorption (TSA) process is briefly described ,which could remove the sulfureted hydrogen, hydrogen cyanide， tar, naphthalene, and benzene with high accuracy, simple operation, high automation, low operation cost and environmental protection, etc．
