Particulized coal is subjected to a series of processing operations to produce a formed coke product. Among the operations are a single stage heating process comprising both carbonizing and calcining operations or, alternatively, a heating process in which carbonizing alone or carbonizing and calcining are conducted in separate stages. At least the carbonizing operation is conducted in the absence of extraneous gas so that the valuable by-product gases driven off from the coal during heating are unadulterated; and the carbonizing operation is conducted with gradual heating in the single stage heating process.
