Abstract

1369614 Synthetic faujacite zeolites AZOTE ET PRODUITS CHIMIQUES SA 7 Sept 1971 [8 Sept 1970] 41750/71 Heading C1A Synthetic faujacite zeolites having the molar composition of the general formula: where x is 0À1-0À8 are prepared by forming a gel of sodium and/or potassium aluminosilicate from a mixture having the following composition expressed as the molar ratio of the oxides: and then adding amorphous silica of size less than 100 Á and aqueous NaOH and/or KOH to form an amorphous mixture having the following composition expressed as the molar ratios of the oxides: and then crystallizing the mixture at a temperature of 20-105‹ C., filtering, washing and drying the precipitate and then finally activating the product. The gel may be formed by adding a solution of sodium and/or potassium silicate to an aqueous solution of sodium aluminate. The particle size of the amorphous SiO2 may be less than 50 Á. The faujacite may be activated by heating to a temperature of 250-600‹ C. under a pressure of less than 10<-1> mm.Hg.
