Abstract: The invention is a method for the reduction of ammonia breakthrough during the manufacture of acrylonitrile comprising introducing a hydrocarbon selected from the group consisting of propane and isobutane; ammonia and an oxygen-containing gas into a lower portion of a fluid-bed reactor containing an ammoxidation catalyst to react in the presence of said catalyst to produce acrylonitrile. The method comprises introducing into the reactor at least one C2 to C5 olefin which will react with at least a portion of the unreacted ammonia and oxygen present in the reactor to substantially reduce the amount of ammonia present in the reactor effluent exiting the reactor.

Abstract: Process for forming multi-component oxide catalysts. According to the invention the key catalytic phase of the catalyst is preformed and the elements of the host-catalyst phase are added together or separately. The key catalytic phase contains a molybdate or a tungstate of Bi, Te, Sb, Sn Cu or mixtures thereof. A representative catalyst is 50% [Bi2Mo3O12] 1/2 [K0.1Ni2.5Co4.5Fe3P0.5Mo10.5 Ox] + 50% SiO2 In the production of this catalyst a preformed bismuth molybdate slurry is added to a host-catalyst slurry. The mixture was then dried, calcined, ground and calcined once again.
