Abstract

The main features of the new ALMAX V/P/O-based catalyst, developed by Lonza, for the fluidized-bed selective oxidation of n-butane to maleic anhydride are presented. Preparation of the catalyst involves a fluidized-bed, superatmospheric thermal treatment in a steam/air flow, which leads to enhanced crystallinity features for the vanadyl pyrophosphate, the catalytically active compound. This new catalyst is compared with catalysts obtained by conventional activation procedures. The main features of the vanadyl pyrophosphate are discussed in relationship with the possible formation of different crystalline forms.
