Abstract: The invention relates to a process for producing metallurgical coke from petroleum coke generated in crude oil refineries, by coking in “heat-recovery” coking ovens, starting from petroleum coke obtained or generated in crude oil refineries and possessing from the outset a volatiles content of 15 to 19 weight percent and an ash fraction of up to 2 Weight percent, this petroleum coke being introduced in densified form into a coking oven of “non-recovery” or “hat-recovery” construction for the purpose of cyclical coking, said oven being equipped with at least one externally heated burner, so that the primary healing space or the secondary heating space below the coking oven chamber, or both, are heated to a temperature of between 1000° C. to 1550° C.
