Catalyst support materials, catalysts, methods of making them and uses thereof

Abstract

Catalyst support materials, catalysts, methods of making such and uses thereof are described. Methods of making catalyst support material include combining anatase titanic slurry with i) a low molecular weight form of silica; and ii) a source of Mo to form a TiO 2 —MoO 3 -SiO 2 mixture. Catalyst support material include from about 86% to about 94% weight anatase titanium dioxide; from about 0.1% to about 10% weight MoO 3 ; and from about 0.1% to about 10% weight SiO 2 . Low molecular weight forms of silica include forms of silica having a volume weighted median size of less than 4 nm and average molecular weight of less than 44,000, either individually or in a combination of two or more thereof. Catalyst include such catalyst support material with from about 0.1 to about 3% weight of V 2 O 5 and optionally from about 0.01% to about 2.5% weight P.

1 . A method of making a catalyst support material comprising:
 a. providing an anatase titania slurry; and   b. combining the anatase titania slurry with i) low molecular weight form of silica and ii) a source of Mo to form a TiO 2 —MoO 3 —SiO 2  mixture, wherein the low molecular weight form of silica comprises a member selected from a group consisting of forms of silica having a volume weighted median size of less than 4 nm and average molecular weight of less than 44,000, and combinations thereof.
