A new cokemaking process carbonizing at low and medium temperature under loading and pressurized conditions has been developed. The productivity and quality of coke in this process were studied by a mathematical simulation model and test ovens with loading and pressurized condition. Following results were obtained : (1) As compared with qualities of conventional coke, approximately the same qualities could be obtained by low and medium temperature carbonization under loading and pressurized conditions. (2) In addition to optimum values of loading and pressurization, direction and timing of loading and pressurization during the carbonization are also important to improve coke qualities. (3) Evaluation by the simulation model indicated that the same productivity of coke in comparison with conventional oven was expected by decreasing coal layer thickness and increasing bulk density of charged coal even at low and medium temperature carbonization.
