Abstract

L'invention concerne un procédé d'obtention d'une zéolite granulaire à partir d'une matière argileuse naturelle. L'invention concerne le traitement de matières naturelles, notamment la production de zéolites granulaires synthétiques. L'invention permet l'utilisation d'une large gamme d'argiles naturelles, elle élargit le choix des matières premières destinées à la production de zéolites granulaires synthétiques, et elle augmente considérablement la tenueur en zéolite active dans les granulés. Pour ce faire, on mélange la matière première initiale à un sel d'aluminium neutre et à de la soude caustique, et on introduit simultanément dans le mélange de réaction de l'hydroxyde d'aluminium ou du dioxyde de silicium, on soumet le mélange à un traitement thermique à la vapeur suivi par une activation thermique, puis on le mélange à un alumino-silico-hydrogel jusqu'à formation d'une suspension homogène. Le sel d'aluminium neutre utilisé peut, par exemple, être du sulfate d'aluminium. On mélange la matière première argileuse, le sel d'aluminium neutre et l'hydroxyde de sodium dans les proportions respectives suivantes: 100 : 0,05 : 0,02. On soumet le mélange à un traitement thermique à la vapeur pendant 10 à 60 minutes à une température comprise entre 110 et 250 °C.
