Title (EN) ZEOLITE AFTER TREATMENT METHOD
(FR) ZÉOLITE APRÈS MÉTHODE DE TRAITEMENT
Abstract:
(EN) This invention relates generally to a process to perform controlled alkaline and acid treatments on inorganic porous solids, yielding superior physico-chemical and catalytic properties, whereas the particle and crystal size is not negatively influenced. Accordingly, the solids obtained in this fashion can be easily recovered from the alkaline solution. The latter being problematic in the state of the art.
(FR) Cette invention concerne d'une manière générale un procédé pour effectuer des traitements acides et alcalins contrôlés sur des solides poreux inorganiques, conférant des propriétés physico-chimiques et catalytiques supérieures sans influencer négativement sur la taille des particules et des cristaux. Les solides ainsi obtenus peuvent donc être facilement récupérés dans la solution alcaline. Ceci étant problématique dans l'état actuel de la technique.
