Abstract

Abstract Translated from French L'invention concerne un procédé de synthèse de zéolites. Ce procédé consiste à former un milieu réactionnel comprenant notamment de l'eau, une source de silice, une source d'alumine, une source d'un agent structurant pouvant fournir des cations choisis dans le groupe constitué par les cations tétrapropylammonium (TPA<+>), tripropylammonium (TRIPA<+>), dipropylammonium (DIPA<+>) et tétrapropylphosphonium (TPP<+>), et des anions fluorure F<->, le pH du milieu étant inférieur à 10, à chauffer ledit milieu réactionnel à une température comprise entre 60 et 230°C, cette seconde étape conduisant à l'obtention d'un solide cristallisé qui est séparé, et à chauffer ledit solide à une température supérieure à 450° C. The invention relates to a process for the synthesis of zeolites. This process consists in forming a reaction medium comprising in particular water, a source of silica, a source of alumina, a source of a structuring agent which can provide cations chosen from the group consisting of tetrapropylammonium cations (TPA <+ >), tripropylammonium (TRIPA <+>), dipropylammonium (DIPA <+>) and tetrapropylphosphonium (TPP <+>), and fluoride anions F <->, the pH of the medium being less than 10, to heat said reaction medium at a temperature between 60 and 230 ° C, this second step leading to obtaining a crystallized solid which is separated, and to heating said solid at a temperature above 450 ° C.
