    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: A method of making a catalyst having the following empirical formula: VSbmAaDdOx where A = Sn, Ti or mixtures thereof, D = at least one element selected from Li, Mg, Na, Ca, Sr, Ba, Co, Fe, Cr, Ga, Ni, Zn, Ge, Nb, Mo, W, Cu, Ti, Ta, Se, Bi, Ce, In, As, B, Al, and Mn, and wherein m = 0.5 to 10 a = 0 to 10 d = 0 to 10 x = number of oxygen atoms necessary to satisfy the valency requirements of the other elements, comprising reacting a monoperoxovanadium ion, VO(O2) , while in aqueous solution with a first portion of an Sb compound which contains Sb, having a valence of 3 , thereby reducing the average valence of the V to less than 5 and oxidizing Sb to a valence state of 5 , removing the water from the solution to form a dried catalyst precursor, and calcining the resulting dried precursor at a temperature in the range of 650 DEG to 950 DEG C to form the catalyst, wherein the improvement comprises adding at least a second portion of an Sb compound after the first portion of Sb compound has been added and has at least partially reacted with the monoperoxovanadium ion.
