ABSTRACT:
Hot coke oven gas is subjected, immediately after the discharge thereof from coke ovens, and without any preliminary cooling operation, to partial oxidation and cracking with an oxygen-containing gas, thereby forming a hot cracked gas rich in carbon monoxide and hydrogen. The hot coke oven gas may be subjected to a desulfurization operation prior to the partial oxidation and cracking. Alternatively, the hot cracked gas may be subjected to a desulfurization operation after the partial oxidation and cracking. When the coke ovens are part of an overall metallurgical installation which includes an air separation and dissociation plant for obtaining substantially pure oxygen, the oxygen-containing gas employed in the partial oxidation and cracking may comprise oxygen enriched gas which is taken from an intermediate stage of the air separation and dissociation plant.
