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., and within a time period of less than 120 h, the volatiles fraction present in the petroleum coke is completely outgassed, giving a metallurgical coke having a CSR strength of at least 44% and a CRI reactivity of less than 33%, being suitable for use as iron- and steelmaking coke The invention also relates to a coking oven which is constructed according to the “non-recovery” or “heat-recovery” coking ovens principle and which comprises a primary heating space, and which is equipped with burners which heat the primary heating space.
