Abstract: The present invention deals with a method to produce uniform quality coke for a blast furnace by quenching coke at a pre-determined rate to produce coke with essentially uniform moisture; further, this invention possesses specific features to produce coke of uniform stability (strength) by equilibrating the temperature of the coke prior to its being quenched. Uniform moisture and uniform stability are very important factors that contribute to the efficient operation of the blast furnace to result in lowering the cost of making a ton of iron. This method is carried out under pressure, in a closed system, and in an environmentally acceptable manner with minimum formation of CO.sub.2. Further, the method possesses additional features which lead to the production of coke of higher stability than obtained conventionally.
