Abstract

Procédé de préparation de catalyseurs au phosphore-vanadium-oxygène et nouveaux produits ainsi obtenus. Dans les modes opératoires classiques pour la préparation de catalyseurs au phosphore-vanadium-oxygène, avec ou sans élément activeur ou support, les composés de phosphore et les composés de vanadium sont mélangés dans des conditions pour former des précurseurs qui sont alors chauffés jusqu'à environ 600 degrés C pour former des catalyseurs convenables pour la transformation d'hydrocarbures saturés en anhydride maléique; dans la présente invention; on forme une nouvelle composition au phosphore-vanadium-oxygène qui est transformée en précurseur. La présente invention est particulièrement utile pour fournir des catalyseurs qui, quand on les emploie pour la transformation d'hydrocarbures saturés en anhydride maléique, fournissent des rendements supérieurs en anhydride maléique.Process for the preparation of phosphorus-vanadium-oxygen catalysts and new products thus obtained. In conventional procedures for the preparation of phosphorus-vanadium-oxygen catalysts, with or without an activator or support element, the phosphorus compounds and the vanadium compounds are mixed under conditions to form precursors which are then heated to about 600 degrees C to form catalysts suitable for the conversion of saturated hydrocarbons to maleic anhydride; in the present invention; a new phosphorus-vanadium-oxygen composition is formed which is converted into a precursor. The present invention is particularly useful for providing catalysts which, when employed for the conversion of saturated hydrocarbons to maleic anhydride, provide higher yields of maleic anhydride.
