Abstract: PROBLEM TO BE SOLVED: To provide a novel process for regenerating an ammonium oxidation catalyst containing molybdenum. SOLUTION: A process for regenerating the ammonium oxidation catalyst containing molybdenum as an active component comprises the step of restoring loss of molybdenum during use of the catalyst in an ammonium oxidation reaction for production of acrylonitrile by treating the catalyst, and selecting ammonium dimolybdate as a feed source of the molybdenum added to the original catalyst for restoring the loss of molybdenum as an improved point.

Abstract: Antimony-based oxide complex catalysts are improved by adding to these catalysts an antimony-containing compound such as Sb 2 O 3 , in an amount of 0.1 to 25% based on an atomic basis of the antimony relative to the antimony already present in the catalyst. In this way a catalyst is produced which gives improved yields for example in the procuction of acrylonitrile by the ammoxidation of propylene.

Abstract: A slurry process for producing a fluid-bed catalyst comprising an antimonate-based oxide complex supported on a catalyst support in which (1) source compounds containing all of the elements of said oxide complex and said support material are combined to form a pre-catalyst slurry, (2) the liquid removed from said pre-catalyst slurry to form a pre-catalyst, and (3) said pre-catalyst is heated at elevated temperature to form said catalyst, in which the support material combined with the source compounds in step (1) is composed of (a) a fumed catalyst support material, such as fumed silica, and (b) a catalyst support material sol, such as a silica sol. The pro-catalyst slurry is formed without the addition of a slurry-derived solid containing fumed catalyst support material and one or more of the source compounds. The process is preferably a single slurry process. The catalyst produced has improved catalytic properties and attrition resistance.
