Supported catalysts for removal of organic sulfur compounds from combustible gases. [Activated Al/sub 2/O/sub 3/ is dehydrated and heated to 1250-1350/sup 0/ to give corundum (. cap alpha. --Al/sub 2/O/sub 3/); porous product soaked in solution of Ni sulfate; pellets are dried at 100/sup 0/; Ni sulfate reduced by coal gas to Ni/sub 3/S/sub 2/ to be used for decomposition of organic S compounds]
Removal of sulfur compounds from gases. [Most of H/sub 2/S and organic S compounds (except thiophene) removed from gas by passage through Zn at 350-500/sup 0/ after passage through hot Fe or Mn oxide layer; ZnO regenerated by heating in oxidizing atmosphere at 700-900/sup 0/]
