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.

Abstract: 1,191,846. Ammonia synthesis catalysts. IMPERIAL CHEMICAL INDUSTRIES Ltd. 8 Aug., 1967 [31 Aug., 1966], No. 38858/66. Heading B1E. [Also in Division C1] A method of rendering oxidation-resistant an ammonia synthesis catalyst comprising metallic iron and one or more promoter compounds comprises treating it with ammonia at a temperature in the range 300‹-500‹C. and at an ammonia concentration such that iron nitride formation takes place and then subjecting it to oxidation at such a temperature that any pyrophoric iron remaining after the ammonia treatment is converted to oxide with decomposition of a substantial proportion of iron nitride. Such a catalyst may comprise Fe 2 N (to the extent of 4-8% nitrogen by weight), a minor proportion of iron oxide and possibly metallic iron. Specified promoters are oxides of K, Ca, Al, Be, Mg, La, Mo and Si.
