METHOD FOR PRODUCING MOLYBDENUM-BISMUTH-IRON CONTAINING COMPOSITE OXIDE FLUID BED CATALYST

摘要

A method for producing a molybdenum-bismuth-iron containing composite oxide fluid bed catalyst for use in an ammoxidation of an organic compound, which comprises a step of subjecting a slurry containing raw materials of specific component elements to a concentration treatment at a temperature range of 50 to 120 DEG C. The method can be employed for producing a catalyst which exhibits high activity and provides an objective ammoxidation product with a high yield, in good reproducibility.
