Abstract

PURPOSE:To economically prepare a metal oxide fluidized bed catalyst having good catalytic activity and selectivity, by a method wherein a particulat catalyst precursor and a phosphorus-containing solid are dry blended under heating and a phosphorus component is volatilized to be deposited on the catalyst precursor. CONSTITUTION:A phosphorus-containing solid pref. containing P, P2O5 or the like and having a particle size of 0.1-1,000mum is dry blended with a metal oxide catalyst precursor which is baked at 300-1,000 deg.C, pref. contains one or more of Sb, Mo and V and has a particle size of 5-300mum and the resulting mixture is held at 300-850 deg.C for a sufficient time in a non-reductive gaseous atmosphere containing H2 or NH3 and O2 to deposit the phosphorus component volatilized from the above mentioned phosphorus solid on the above mentioned catalyst precursor. By this method, a phosphorus-containing metal oxide fluidized bed catalyst used in oxidation, ammoxidation or oxidative dehydrogenation reaction of an org. compound is obtained. In this case, the deteriorated catalyst of which the activity is lowered by using the same in the above mentioned reactions can be used as the bove-mentioned catalyst precursor.
