Abstract
Production of coke from coal is improved by mixing self-feeding coal with compacted non self-feeding coal prior to carrying out the coking process. Preferably, there is about 10% to about 60% by weight of the non self-feeding coal based on the total charge. Binders may be used and it is preferred that the non self-feeding coal be preheated to approximately 150.degree. C. to 250.degree. C. prior to mixing. In the event that an aqueous emulsion is used as the binder, the preheating step may be omitted. Coke of superior abrasion resistance is obtained by the foregoing method.
