Abstract

Zeolite Y was synthesized hydrothermally from Elefun kaolinite clay. The raw kaolinite was calcined at 8500C to obtain more reactive clay (metakaolin). The metakaolin was dealuminated using non-heating methods to obtain the optimum dealumination route desired silica to alumina ratio between 3 and 7. The non-heating method proved successful in producing a desired ratio of 4 which was used in producing the aluminosilicate gel. The aluminosilicate gel was aged for 7 days at 950C for 36 hours with varying Na2O/SiO2 ratios of 0.60, 0.65, 0.70, 0.75 and 0.80 to produce zeolite Y. The synthesized zeolites were characterized by X-ray diffraction (XRD) analysis. The effect of NaOH concentration was studied using the XRD patterns of synthesized zeolite Y samples with reference to a standard zeolite Y. The results indicated zeolite Y of low crystallinity accompanied with other impure phases. Furthermore, the concentration of NaOH improved the intensity of the zeolite Y crystal peaks. The Na2O/SiO2 ratio that gave the highest crystallinity optimal ratio was found to be 0.75 with NaOH concentration of 3.88
