At present, coke ovens in Japan have 34 years in average working life. Thus, the lives of most coke oven batteries should come to an end soon. It is thus anticipated that if the coke oven batteries are not replaced, the amount of coke would become short. Coke oven operation has various disadvantages, such as the restriction on the coal brands that a strongly-coking coal has to be used as a raw coal for coke-making, low productivity, the inherent tendency for much energy to be consumed, environmental pollution and so on. In this paper, Research & Development of new cokemaking process were discussed.
