description A complete catalyst for the oxidation of SO2 in O2-containing gas streams contains vanadium oxide and alkali metal oxide or alkali metal sulphate as active substance, silicon and/or aluminium in the oxide form to increase the surface area and TiO2 in the form of anatase and/or rutile as support material and ceramic binder. The metals in these finely particulate sintered components, performing discrete functions, are present in defined atomic ratios. The finely particulate sintering is carried out by a production process principally by means of diverse drying, calcination and sintering conditions. The main area of application of the invention is the desulphurisation of waste gases from combustion processes and industrial plants.
