    Abstract: A process for producing a fluid catalyst having good activity from a coarse catalyst wherein said fluid catalyst is suitable for oxidation, ammoxidation or oxidative dehydrogenation reaction of hydrocarbons which comprises crushing a fluid catalyst, a greater part of which is composed of particles having a large particle size, to produce finely-divided particles, adjusting the distribution of particle size of said catalyst so that the amount of particles of a size of about 20.mu. or less is about 30% by weight or less of the total weight of catalyst particles and the amount of particles having a weight average particle size is 90% or less based on the catalyst prior to crushing, and thereafter calcining said catalyst at a temperature of about 500.degree. C. - about 1000.degree. C. under a non-reducing atmosphere.

    Abstract: A process for producing acrylonitrile by the vapor-phase catalytic ammoxidation of propylene, which comprises(I) reacting propylene, a molecular oxygen-containing gas and ammonia in the presence of a catalyst expressed by the following empirical formulaFe.sub.a Sb.sub.b Mo.sub.c Me.sub.d Te.sub.e Q.sub.f Na.sub.g O.sub.h. (SIO).sub.iwherein Me is at least one element selected from the group consisting of V and W,Q is at least one element selected from the group consisting of Cu, Mg, Zn and Ni, andthe subscripts a, b, c, d, e, f, g, h and i each represents atomic ratios such that when a=10; b=13 to 28; c=0.1 to 2.5; d=0.05 to 1; e=0.2 to 5; f=0 to 4 (in which case b=13 to 20), or f=2 to 6 (in which case b=20 to 28); g=0 to 3; h=the number of oxygens corresponding to the oxide formed by the combination of the components, and i=25 to 200;in a fluidized bed catalytic reaction zone at a temperature of about 380 to about 500.degree. C. and a pressure of about 0.2 to about 3 kg/cm.sup.2 -G while adjusting the propylene/oxygen/ammonia molar ratio to about 1:about 1:about 0.8 to about 1:about 4:about 3;(II) the catalyst being prepared by(1) intimately mixing starting materials for the Fe, Mo, Me, Te and Q components in a form soluble in water or nitric acid, a starting material for the Sb component, and silica sol which may or may not contain an Na component, thereby to form a slurry containing these components and having a non-volatile solids content of about 10 to about 50% by weight;(2) so that the composition of the final catalyst is within the range expressed by the empirical formula above;(3) spray-drying the resulting slurry, and(4) calcining the resulting spray-dried particles at a temperature of about 600 to about 950.degree. C. thereby to form a catalyst with a composition within the above empirical formula and with all of the Mo, Me, and Te components substantially dissolved in an iron/antimony oxide compound (FeSbO.sub.4) in the form of a solid solution.
