Abstract (en)
[origin: WO2011128830A1] A catalyst for the oxidation of SO2 to SO3, a process for producing it and its use in a process for the oxidation of SO2 to SO3 are provided. The catalyst comprises active substance comprising vanadium, alkali metal compounds and sulfate applied to a support comprising naturally occurring diatomaceous earths, wherein the support comprises at least one relatively soft naturally occurring uncalcined diatomaceous earth which has a percentage reduction of at least 35% in its D50 value determined in a particle size determination according to the dry method in comparison with the wet method.
