ABSTRACT:
A catalyst for the oxidation of sulfur dioxide comprising vanadium supported by a microporous carrier is disclosed. The microporous carrier is characterized by a silica content greater than 85 percent, an alumina content greater than 3 but less than 5 percent, an iron content less than 2.0 percent, a surface area greater than 10 m.sup.2 /g, a bulk density more than 0.10 and less than 0.35 g/cc, a mean pore diameter greater than 0.3 and less than 2.5 micrometers, a pore volume greater than 2 ml/g, and a porosity greater than 65 percent. The product containing vanadium is easily extrudable into pellets or other shaped forms to give both a durable and highly active catalyst. Diatomaceous earths of the Actinoptychus class, especially Actinoptychus undulata, and of the Coscinadiscus class meet the criteria stated above, as do some acid-leached montmorillonite clays.
