Abstract
A process is provided for preparing supported catalysts by impregnating a pre-formed support with a solution of a metal alkoxide and contacting the impregnated support with a solution of at least one additional catalyst component. This process is particularly suitable for forming attrition resistant fluidizable catalysts. Catalysts prepared by this method are useful in various reaction processes, and may be utilized in oxidation processes such as the production of maleic anhydride from 4 carbon atom hydrocarbons.

A process for the preparation of a supported catalyst comprising
- impregnating a pre-formed catalyst support with a solution of an alkoxide of at least one metal selected from vanadium, molybdenum, antimony, copper, niobium, tantalum, zinc, zirconium, boron and mixtures thereof,
- contacting the impregnated support with a solution of at least one additional catalyst component to form the catalyst in situ, and
- drying the catalyst-containing support.
A process for the preparation of a supported catalyst containing the mixed oxides of vanadium and phosphorus comprising
- impregnating a preformed catalyst support with a first solution of a vanadyl alkoxide,
- contacting the impregnated support with a second solution of the phosphorus component to form the catalyst in situ,
- drying the catalyst containing support.
A supported catalyst containing at least one metal component prepared by
- impregnating a pre-formed catalyst support with a solution of an alkoxide of at least one metal
- selected from vanadium, molybdenum, antimony, copper, niobium, tantalum, zinc, zirconium, boron and mixtures thereof,
- contacting the impregnated support with a solution of at least one additional catalyst component to form the catalyst in situ, and
- drying the catalyst-containing support.
A supported catalyst containing the mixed oxides of vanadium and phosphorus prepared by
- impregnating a preformed catalyst support with a solution of a vanadyl alkoxide,
- contacting the impregnated support with a solution of the phosphorus component to form the catalyst in situ,
- drying the catalyst containing support.
