A new cokemaking process carbonizing at low and medium temperature under loadingand 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 andmedium temperature carbonization under loading and pressurized conditions.
(2)In addition to optimum values of loading andpressurization, direction and tirning of loading and pressurization during the carbonization are also important to improve coke qualities.
(3)Evaluation by the sirnulation model indicated that the sarne 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.
