CA 2044067

A solid catalyst for the oxidation of sulfur dioxide in gas currents containing oxygen, which catalyst includes vanadium oxide and alkali metal oxides, alkali metal sulfates or mixtures thereof, as an active substance, silicon, aluminum, or mixtures thereof, in oxide form, for surface area enlargement, and titanium dioxide in anatase form, rutile form, or mixtures thereof, as a carrier material and a ceramic binder. The metals in these finely sintered components which impart discrete functions are present in certain atomic ratios. The fine sintering takes place according to a production method especially by means of differentiated conditions of drying, calcining and sintering. One use for the invention is the desulfurization of waste gases from combustion processes and industrial plants.
