CATALYSTS SUITABLE FOR REMOVING SULPHUR COMPOUNDS FROM INDUSTRIAL GASES, PROCESS FOR PREPARING THE SAME AND THEIR USE

摘要

Catalysts which allow volatile sulphur compounds to be removed from industrial gases have an inorganic, abrasion-resistant, non-combustible support uniformly impregnated with oxides/hydroxides of the elements from the group consisting of niobium and tantalum, possibly with oxides/hydroxides of the elements of the second main group of the periodic table or with oxides/hydroxides of manganese, with at least one oxide/hydroxide of the elements from the group consisting of hafnium, lanthanium and the lanthanides, possibly with oxides/hydroxides of the elements from the group consisting of tungsten and molybdenum.
