Abstract

LE TRAITEMENT THERMIQUE DE PRECURSEURS DE CATALYSEURS AU PHOSPHORE-VANADIUM-OXYGENE A DES TEMPERATURES COMPRISES ENTRE ENVIRON 150C ET ENVIRON 300C, PENDANT UNE PERIODE D'ENVIRON 1 HEURE A ENVIRON 6 HEURES, AVANT DE SOUMETTRE A DES CONDITIONS DE CALCINATION FOURNIT DES PRECURSEURS CATALYTIQUES AYANT UNE RESISTANCE AUGMENTEE A L'ECRASEMENT ET UNE RESISTANCE AUGMENTEE A L'USURE PAR FROTTEMENT; CES PRECURSEURS, PAR CALCINATION, SONT TRANSFORMES EN CATALYSEURS AU PHOSPHORE-VANADIUM-OXYGENE QUI SONT UTILES POUR LA TRANSFORMATION D'HYDROCARBURES NON AROMATIQUES, PARTICULIEREMENT LE N-BUTANE, EN ANHYDRIDE MALEIQUE.THERMAL TREATMENT OF PHOSPHORUS-VANADIUM-OXYGEN CATALYST PRECURSORS AT TEMPERATURES BETWEEN APPROXIMATELY 150C AND ABOUT 300C, FOR A PERIOD OF ABOUT 1 HOUR TO ABOUT 6 HOURS, BEFORE SUBMITTING TO PREVIOUS CONDITIONS FOR SUPPLY CATCINATION CALCINATION INCREASED CRUSHING RESISTANCE AND INCREASED FRICTION WEAR RESISTANCE; THESE PRECURSORS, BY CALCINATION, ARE TRANSFORMED INTO PHOSPHORUS-VANADIUM-OXYGEN CATALYZERS WHICH ARE USEFUL FOR THE TRANSFORMATION OF NON-AROMATIC HYDROCARBONS, PARTICULARLY N-BUTANE, INTO MALEIC ANHYDRIDE.
