Abstract
Improved catalysts for oxidation of sulfur dioxide which are alkali metal-promoted vanadium catalysts which are further promoted by gold. Improved methods employing such catalyst for oxidation of sulfur dioxide and for manufacture of sulfuric acid. Improved methods for multiple step oxidation of sulfur dioxide in which the last oxidation step is carried out employing improved catalysts of this invention at temperatures lower than 400° C.
