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.
