介绍和分析了焦炉煤气制天然气的技术，重点为甲烷化技术路线。讨论甲烷化的工艺条件，包括催化剂、反应压力和温度及反应器。指出企业建设项目时，必须结合自身情况慎重选择成熟可靠的先进技术。对于有大量氢气需求的企业，可以选择焦炉煤气同时制氢和天然气技术；而对于有丰富CO2资源的企业，选择补加CO2进行甲烷化制天然气可获得较好的经济和环境效益。

The process technologies for conversion of coke oven gas (COG) to synthetic natural gas (SNG) were presented and analyzed with the emphasis on the methanation route. The process conditions including catalysts, reaction pressure and temperature as well as reactors for methanation of COG were discussed. It was also pointed out that the enterprises develop coke oven gas to SNG projects should carefully choose the advanced, proven and reliable technology according to their own situation. For those having a large requirement of H2, the process of coproduction of H2 and SNG could be selected, and for those having abundant CO2 resource, the process of producing SNG by supplying CO2 to COG to methanation could obtain better economic and environmental benefits.
