SO _→ SO CONVERSION CATALYSTS Russian patent published in 1999 - IPC

Abstract RU 2134612 C1

FIELD: oxidation catalysts. SUBSTANCE: catalyst consists of vanadium, alkali metal, and sulfur oxide applied on natural or synthetic silica in following amounts, wt %: V₂O₅ 5.5-12.0, K₂O 8-20, Na₂O up to 4.5, Cs₂O up to 20, Rb₂O up to 20, and SO₃ 12-35. Carrier is distinguished by containing pores with radii between 37.5 and 65000 with total volume between 0.35 and 0.95 cu. cm/cu.cm, content of pores with radii 1800 to 65000 ranging from 15 to 60% and not being below 0.10 cu.cm/cu.cm. EFFECT: increased catalyst activity at low temperatures (405 C) and strength. 1 tbl, 11 ex
