Title (EN) A CATALYST FOR GASEOUS PARTIAL OXIDATION OF PROPYLENE AND METHOD FOR PREPARING THE SAME
(FR) CATALYSEUR POUR L'OXYDATION GAZEUSE PARTIELLE DE PROPYLENE ET SON PROCEDE DE PREPARATION
Abstract:
(EN) The present invention relates to a method for preparing a catalyst which is used in a process of producing acrolein and acrylic acid by the reaction of oxygen-containing gas and propylene. According to the present invention, a sublimable material, such as urea (NH2CONH2), melamine (C3H6N6), amonium oxalate (C2H8N2O4), methyl oxalate (C4H6O4) or naphthalene (C10H8), is added as a catalyst additive in the preparation of the catalyst. Using the catalyst prepared by the present invention, acrolein and acrylic can be produced at high yield.
(FR) L'invention concerne un procédé de préparation d'un catalyseur utilisé dans un procédé de production d'acroléine et d'acide acrylique, par la mise en réaction d'un gaz contenant de l'oxygène et du propylène. Selon l'invention, une matière sublimable, telle que l'urée (NH2CONH2), la mélamine (C3H6N6), l'oxalate d'ammonium (C2H8N2O4), l'oxalate de méthyle (C4H6O4) ou le naphtalène (C10H8), est ajouté(e) en tant qu'additif de catalyseur dans la préparation du catalyseur. Le catalyseur préparé selon l'invention est utilisé pour la production d'acroléine et d'acrylique avec un rendement élevé.
