Abstract
L'INVENTION CONCERNE UN CATALYSEUR RESISTANT A L'ATTRITION. SELON L'INVENTION, IL COMPREND UN SUPPORT POREUX ET ESSENTIELLEMENT INERTE POUVANT MAINTENIR UN MATERIAU CATALYTIQUEMENT ACTIF ET FINEMENT SUBDIVISE SUR SA SURFACE EXTERNE, LE SUPPORT ETANT MOUILLE D'UNE QUANTITE SUFFISANTE DE SOL DE SILICE AQUEUX CONTENANT DE 20 A 40 EN POIDS DE SILICE, POUR DONNER UN SUPPORT CONTENANT JUSQU'A LA QUANTITE MAXIMUM DE SOL DE SILICE QUE LE SUPPORT PEUT ABSORBER SANS AVOIR L'ASPECT DE LIQUIDE SUR SA SURFACE EXTERNE; ET UN OXYDE CATALYTIQUEMENT ACTIF ET FINEMENT SUBDIVISE POUR LA CONVERSION PAR OXYDATION D'ALDEHYDES A INSATURATION OLEFINIQUE EN ACIDES INSATURES CORRESPONDANTS, TOTALEMENT CALCINE A DES TEMPERATURES DE 360 A ENVIRON 420C, L'OXYDE AYANT ETE ENDUIT A LA SURFACE DU SUPPORT POREUX AFIN DE PRODUIRE UN REVETEMENT D'ASPECT UNIFORME, LE CATALYSEUR RESULTANT ETANT SECHE ET AYANT UN INDICE SPECIAL D'ATTRITION NE DEPASSANT PAS 5 EN POIDS; LE DESSIN JOINT MONTRE UN TAMBOUR 10 A UTILISER POUR LA PREPARATION DU CATALYSEUR, POURVU D'UNE CHICANE 14. L'INVENTION S'APPLIQUE NOTAMMENT A LA CONVERSION D'ACROLEINE EN ACIDE ACRYLIQUE.
