Abstract: The technology of coke oven gas to methanol is a characteristic integrated utilization process of coke oven gas in China,which shows important significance to both the mass production and environmental protection by implementing resource utilization of coke oven gas and reducing the emission of pollutant.Based on the National Key R & D Program of China 'study on the criterion of key technology in cycle linkage of private industry',the comparative studies between the enterprises survey and literature reports were carried out and the effects of main impurities,such as oxygen content,sulfide,ammonia,benzene,naphthalene,hydrogen cyanide,tar and dust on the subsequent process of methanol were analyzed.As expect,the quality requirements of coke oven gas for industrial methanol production are proposed,which is useful to guide the process management and quality control in coke production and coke oven gas purification for enterprises,and thus,providing qualified raw material gas for methanol production.
