Abstract
Modified Claus furnace containing, in addition to primary reaction chamber, a secondary chamber in heat exchange with said primary reaction chamber wherein H.sub.2 S is cracked to supply hydrogen needed downstream in a clean-up system. This eliminates the need for supplemental hydrogen generator now usually provided for in a sulfur recovery system. A catalyst such as cobalt-molybdenum can be used in the secondary reaction chamber.
