A simulated moving bed reactor was constructed by assuming a new coke oven which produces metallurgical coke rapidly and continuously. Using this reactor, a trial was made to produce metallurgical coke from 4 kinds of coals. The point of the new coke oven lies in a unigue heating pattern of coal: rapid heating up to 450-500°C, holding time for 20 to 30 min, and subsequent slow heating up to 800°C. This heating pattern of coal was realized by use of the simulated moving bed reactor, and the coke comparable to a commercial coke from viewpoint of the CO2 reactivity and the micro strength was produced in about 2 h from highly coking coals. The coke comparable to the commercial coke could also be produced from a slightly coking coal by mixing it with a highly coking coal or by adding a pitch to it, although the coke could not be produced from the slightly coking coal only.
