  • Shaped catalyst body for partial oxidation reactions
    Patent number: 8048820
    Abstract: The invention relates to a shaped catalyst body for preparing maleic anhydride, which comprises mixed oxides of vanadium and of phosphorus as catalyst components. To develop a generic shaped catalyst body further so that it has improved properties, it is proposed that the basic geometric body enveloping the shaped catalyst body (100; 200) be a prism (180) having a first triangular face and a second triangular face and the shaped catalyst body (100; 200) be provided with three through openings (111, 121, 131; 211, 221, 231) which extend from a first face of the shaped body (100; 200) which contacts the first triangular face of the prism (180) to a second face of the shaped body (100; 200) which contacts the second triangular face of the prism (180).
