Abstract
Antimonate-based redox catalysts are produced by a single slurry technique using a silica sol and fumed silica to supply the catalyst support.
Claims12
In a single 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) liquid is 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, the improvement wherein the support material combined with said source compounds in step (1) is composed of (a) a fumed catalyst support material and (b) a catalyst support material sol.
The process according to 8 wherein b/c is 2/10 to 4/10.
In a 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, the improvement wherein the support material combined with said source compounds in step (1) is composed of (a) a fumed catalyst support material and (b) a catalyst support material sol, said pre-catalyst slurry being formed without the addition of a slurry-derived solid containing said fumed catalyst support material and one or more of said source compounds.
