SO-INTO-SO CONVERSION CATALYST Russian patent published in 2005 - IPC

Abstract RU 2244590 C1

FIELD: oxidation catalysts.

SUBSTANCE: SO2-into-SO3 conversion catalyst contains following active components: vanadium oxide, alkali metal (K, Na, Rb, Contains) oxides, sulfur oxides, and silica framework formed from natural and/or synthetic silica and having pores with radii up to 65000 , among which fraction of pores with radii larger 10000 does not exceed 50%, while content of sulfuric acid-insoluble vanadium compounds (on conversion to V2O5) does not exceed 4.0% by weight. Fraction of pores with radii 1000-10000 does not exceed 35% and that less than 75 at most 9%.

EFFECT: improved performance characteristics of catalyst operated in reactor zones at medium and maximum temperature due to under conditions activity at 420-530оС.
