Zusammenfassung: | a) Process and device for the production of spherical catalyst blanks. b) Process characterised in that a peptisation suspension which has a viscosity corresponding to a flow time of 10 to 120 seconds in a 50-ml pipette is introduced continuously into a draining device which is given a speed of 30 to 300 rev/min and the spherical particles formed are then hardened by passing vertically through the coagulation layer and, after mechanical separation, are subjected to a heat treatment. c) The invention relates to a process and device for the production of spherical catalyst blanks.
A)PROCEDE ET DISPOSITIF POUR LA PRODUCTION D'EBAUCHES SPHERIQUES DE CATALYSEUR,B)PROCEDE CARACTERISE EN CE QU'UNE SUSPENSION DE PEPTISATION AYANT UNE VISCOSITE CORRESPONDANT A UNE DUREE D'ECOULEMENT D'UNE PIPETTE DE 50ML DE 10 A 120SECONDES EST INTRODUITE EN CONTINU DANS UN DISPOSITIF D'EGOUTTAGE AUQUEL ON A CONFERE UNE VITESSE DE 30 A 300TMIN. ET ENSUITE LES PARTICULES SPHERIQUES FORMEES SONT DURCIES PAR UN PASSAGE VERTICAL A TRAVERS LA COUCHE DE COAGULATION ET, APRES SEPARATION MECANIQUE, SONT SOUMISES A UN TRAITEMENT THERMIQUE,C)L'INVENTION CONCERNE UN PROCEDE ET DISPOSITIF POUR LA PRODUCTION D'EBAUCHES SPHERIQUES DE CATACLYSEUR. |
