Coking coals. Although chemical composition alone cannot be used to predict whether a coal is suitable for coking, prime coking coals generally have volatile matter contents of 20 to 32 percent—i.e., the low- and medium-volatile bituminous ranks. When heated in the absence of air, these coals first become plastic, then undergo decomposition, and finally form coke when the decomposed material ...
