Abstract
Attrition resistant bismuth-containing metal/oxygen compositions comprising the infusion and reaction product of alumina and at least one bismuth oxide, or compound convertible by heat to such bismuth oxide, which bismuth oxide is susceptible of undergoing infusion and reaction with the alumina, are useful in metal oxide-catalyzed reactions. The compositions are especially useful in reactions which involve reaction conditions of high stress, for example, vapor phase oxidations under fluidized bed conditions.
