In coke ovens, hot coke oven gas (Hot COG) is generated during carbonization as by-products. To avoid the deposition of tar and coking, a component of Hot COG, tar are removed and recovered through rapid ammonia liquor cooling. In this conventional process, however, the Hot COG's high-temperature sensible heat is not effectively used. This research and development aims to develop technologies to produce synthesis gas that can be converted to clean liquid fuels, such as methanol or DME (dimethyl ether) , by reforming the Hot COG with tar generated in coke ovens, thereby making use of the heat energy of Hot COG .
