摘要： A method of manufacturing desulfurization and denitration active cokes of a high strength, comprising the steps of molding a mixture of a plurality of kinds of coal of different caking capacities and a binder, wherein the coal of high caking capacities are compounded at a 10-50 wt.% point, subjecting this molded product to oxidation in an atmosphere of an oxygen concentration of 1-18 capacity % and a temperature of 50-250 DEG C, carbonizing the resultant product under the conditions including an oxygen concentration of not higher than 8 capacity %, a temperature increasing rate of 10-50 DEG C/min and a final temperature to be attained of 600-900 DEG C, and then subjecting the carbonized product to oxidation again in an atmosphere of an oxygen concentration of 3-18 capacity % and a temperature of 200-600 DEG C. The desulfurization and denitration active cokes of a high strength thus obtained are then treated with concentrated sulfuric acid, whereby cokes having a high denitration activity from the first can be obtained.
