Research and development of new cokemaking process (SCOPE21) was conducted in Japan from 1994 to 2003 by the Japan Iron and Steel Federation (JISF). Pilot plant scale test of SCOPE21 process was conducted successfully and targets of the project were confirmed. SCOPE21-type new coke oven battery was constructed at Nippon Steel Oita works and the operation of new coke plant started in 2008. The coke production capacity is 1 million ton per year. At present, high quality coke has been produced in this process using high blending ratio (over 50%) of non- or slightly-caking coal. The new cokemaking process is in operation very smoothly.
