Patent

CA 2627481

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).

L'invention concerne un corps moulé de catalyseur pour la fabrication d'anhydride maléique, lequel corps contient des oxydes mixtes de vanadium et de phosphore comme composants de catalyseur. Pour transformer un corps moulé de catalyseur du type générique de telle sorte qu'il présente de meilleures propriétés, on propose selon l'invention que le corps géométrique de base qui forme l'enveloppe du corps moulé (100; 200) de catalyseur soit un prisme (180) doté d'une première et d'une deuxième surfaces triangulaires, et que le corps moulé (100; 200) de catalyseur soit traversé par trois ouvertures traversantes (111, 121, 131; 211, 221, 231) qui s'étendent depuis une première surface du corps moulé (100; 200) qui sous-tend la première surface triangulaire du prisme (180) jusqu'à une deuxième surface du corps moulé (100; 200) qui sous-tend la deuxième surface triangulaire du prisme (180).
