Abstract
Official abstract text for this publication.
A process for producing geometric shaped catalyst bodies K whose active material is a multielement oxide of stoichiometry [Bi 1 W b O x ] a [Mo 12 Z 1 c Z 2 d Fe e Z 3 f Z 4 g Z 5 h O y ] 1 , in which a finely divided oxide Bi 1 W b O x with the particle size d 50 A1 and, formed from element sources, a finely divided intimate mixture of stoichiometry Mo 12 Z 1 c Z 2 d Fe e Z 3 f Z 4 g Z 5 h with the particle size d 90 A2 are mixed in a ratio of a:1, this mixture is used to form shaped bodies and these are treated thermally, where (d 50 A1 ) 0.7 ·(d 90 A2 ) 1.5 ·(a) −1 ≧820. A shaped catalyst body obtained by the process. A catalyst obtained by grinding the shaped catalyst body. A process for heterogeneously catalyzing the partial gas phase oxidation of an alkane, alkanol, alkanal and/or an alkenal of 3 to 6 carbon atoms using the catalyst.
First claim
Opening claim text (preview).
The invention claimed is: 1. A shaped catalyst body comprising, as an active material, a multielement oxide having stoichiometry (I): [Bi 1 W b O x ] a [Mo 12 Z 1 c Z 2 d Fe e Z 3 f Z 4 g Z 5 h O y ] 1 (I), wherein: Z 1 is nickel, cobalt, or a mixture thereof; Z 2 is an alkali metal, an alkaline earth metal, thallium, or any mixture thereof; Z 3 is zinc, phosphorus, arsenic, boron, antimony, tin, cerium, vanadium, chromium, bismuth, or any mixture thereof…
