ABSTRACT:
Certain zeolite materials have been found to be effective zeolite adsorbents-catalysts for the adsorption and conversion of sulfuric compounds to elemental sulfur. These zeolites adsorb hydrogen sulfide and sulfur oxides and promote the reaction of these materials so as to produce sulfur. These useful zeolites are the hydrogen forms of the zeolite materials and sodium exchanged hydrogen zeolites, especially mordenite. These zeolite adsorbents-catalysts are very useful for the removal of small amounts of hydrogen sulfide and sulfurous oxide from effluent streams such as effluent streams from Claus reactors.
