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: Process for forming multi-component oxide catalysts. According to the invention the key catalytic phase of the catalyst is preformed and the elements of the host-catalyst phase are added together or separately. The key catalytic phase contains a molybdate or a tungstate of Bi, Te, Sb, Sn Cu or mixtures thereof. A representative catalyst is 50% [Bi2Mo3O12] 1/2 [K0.1Ni2.5Co4.5Fe3P0.5Mo10.5 Ox] + 50% SiO2 In the production of this catalyst a preformed bismuth molybdate slurry is added to a host-catalyst slurry. The mixture was then dried, calcined, ground and calcined once again.

Abstract: 1433168 Esters from unsaturated alcohols and aldehydes STANDARD OIL CO 19 Sept 1973 43892/73 Heading C2C Acrylic and methacrylic esters are prepared by adding an aliphatic or aromatic alcohol containing up to ten carbon atoms to acrolein or methacrolein and reacting the mixture with molecular oxygen in the presence of an oxidation catalyst at a temperature of from 250 to 450 C. The alcohol is suitably an alkanol of 1 to 4 carbon atoms, and the catalyst suitably contains molybdenum, vanadium and/or tungsten. Reference has been directed by the Comptroller to Specification 1,266,457.
