AMMOXIDATION IN FLUIDIZED BED REACTOR

摘要

PROBLEM TO BE SOLVED: To provide a method for ammoxidation for hydrocarbon by a vapor- phase catalytic reaction, capable of improving contact efficiency between catalyst particles and a raw material and a reaction result (yield of objective reaction product). SOLUTION: In subjecting a raw material to be oxidized by ammoxidation by a vapor-phase catalytic fluidized bed reaction, the reaction is carried out by a fluidized bed reactor for supplying an oxygen-containing gas from a feed opening from the bottom of the fluidized bed and a raw material to be subjected to ammoxidation from a feed opening positioned at 30-250% the fluidized bed height in a stationary state of the fluidized solid substance measured from the feed opening of the oxygen-containing gas so as to form a fluidized bed having 50-300kg/m<3> raw material fluidized solid substance density to be subjected to ammoxidation and <=1m/s gas flow velocity.
