Abstract: STEAM IS USED KEEP THE QUIESCENT ZONE ABOUT 200*F. COOLER THAN THE TURBULENT ZONE OF A FLUID-BED REACTOR UTILIZED IN THE AMMOXIDATION OF MONOOLEFINS TO UNSATURATED NITRIELS. STEAM ESCAPING FROM THE QUIESCENT ZONE INTO THE TURBULEN ZONE PREVENTS FUSION OF POWDERY CATALYST IN THE PRESENCE OF OXYGEN AND THE ADHESION OF FUSED CATALYST TO INTERNALS IN THE TOP PORTION OF THE REACTOR.

Abstract: High per pass conversions to acrylonitrile and acrylic acid or methacrylonitrile and methacrylic acid and desirable commercial flexibility are realized by reacting propylene or isobutylene with molecular oxygen and about 0.1 to about 0.9 moles of ammonia per mole of olefin in the presence of two catalysts. The first catalyst is an ammoxidation catalyst, and the second catalyst is an oxidation catalyst.
