Document Type and Number:
Japanese Patent JPS59142847
Kind Code:
A
Abstract:
An improved oxidation catalyst, well adopted for the conversion of H2S-containing acid gases at least in part to elemental sulfur, is facilely prepared by (i) hydrothermally treating at least a portion of an active alumina support, and (ii) then impregnating said at least partially hydrothermally treated support with a catalytically effective amount of a catalytically active oxide phase which comprises the oxides of at least one of the metals, Fe, Cu, Ag, W, Co, Ni, Bi, Cr and Cd, with the proviso (iii) that at least one rare earth oxide, alkaline earth metal oxide, zirconium oxide or silica compound, or any precursor compound thereof, is incorporated into the catalyst during either of the steps (i) or (ii).
