A process for the removal of oxidizable sulfur compounds from a waste gas which comprises: (a) mixing a waste gas containing compounds oxidizable to sulfur oxides with molecular oxygen and oxidizing said compounds to sulfur oxides; (b) contacting the oxidized gas with a metal oxide absorbent capable

A process for the removal of oxidizable sulfur compounds from a waste gas which comprises: (a) mixing a waste gas containing compounds oxidizable to sulfur oxides with molecular oxygen and oxidizing said compounds to sulfur oxides; (b) contacting the oxidized gas with a metal oxide absorbent capable of absorbing sulfur oxides at a temperature of between about 100°C. and 800°C., and absorbing sulfur oxides with said metal oxide absorbent; (c) simultaneously, in the presence of a hydrocarbon cracking catalyst and at a temperature of between about 375°C. and about 1,200°C., cracking a hydrocarbon, regenerating the spent metal oxide absorbent and contacting the absorbent with steam to form hydrogen sulfide which can be separated from the cracked hydrocarbon and recovered as elemental sulfur.
