ABSTRACT:
A process for preparing a metal oxide catalyst for a fluidized bed process, which comprises adjusting the pH of an aqueous slurry containing an iron compound, an antimony compound, a phosphorus compound, and a silica carrier material as essential elements, with the atomic ratio of phosphorus to antimony being at least 0.1:1, to a pH of 3 or less, spray drying the slurry, and calcining the resulting particles; which catalyst exhibits excellent activity and physical properties suitable for use in a fluidized bed process and can be obtained with good reproducibility.
