Process for the preparation of spherical aromatisation catalysts

a) Process for the preparation of spherical aromatisation catalysts. b) Process characterised in that the peptisation suspension of high viscosity, made up of aluminium oxide hydrogel is converted by means of a hollow body provided with orifices on its periphery into spherical particles which solidi...

Beschreibung
Zusammenfassung:	a) Process for the preparation of spherical aromatisation catalysts. b) Process characterised in that the peptisation suspension of high viscosity, made up of aluminium oxide hydrogel is converted by means of a hollow body provided with orifices on its periphery into spherical particles which solidify by vertically passing through a coagulation layer and are then dried in a manner known per se, calcined at a temperature above 700 K and are then impregnated with the active components and again treated at a temperature higher than 725 K. c) The invention relates to a process for the preparation of spherical aromatisation catalysts. A)PROCEDE POUR LA PREPARATION DE CATALYSEURS SPHERIQUES D'AROMATISATION.B)PROCEDE CARACTERISE EN CE QUE LA SUSPENSION DE PEPTISATION A VISCOSITE ELEVEE, FORMEE D'HYDROGEL EN OXYDE D'ALUMINIUM EST TRANSFORMEE AU MOYEN D'UN CORPS CREUX MUNI D'ORIFICES SUR SA PERIPHERIE, EN PARTICULES SPHERIQUES, SE SOLIDIFIANT PAR PASSAGE VERTICAL A TRAVERS UNE COUCHE DE COAGULATION ET ENSUITE, SONT SECHEES DE MANIERE CONNUE EN SOI, CALCINEES A UNE TEMPERATURE SUPERIEURE A 700K, PUIS SONT IMPREGNEES AVEC LES COMPOSANTS ACTIFS ET TRAITEES A NOUVEAU A UNE TEMPERATURE SUPERIEURE A 725K.C)L'INVENTION CONCERNE UN PROCEDE POUR LA PREPARATION DE CATALYSEURS SPHERIQUES D'AROMATISATION.
