- Abstract
The process for the synthesis of flyash-based superfine zeolites-Y (FAZ) were presented, which basically included the alkaline fusion treatment of fly ash (FA), the gels formation by dissolved and aged, following hydrothermal crystallization. A detailed investigation was carried out to determine the effects of conditions of synthesis superfine zeolite-Y. The crystallization structure of zeolite-Y was characterized by X-ray diffraction(XRD) and scanning electron microscope(SEM). The experimental results show that the optimized conditions: Fly ash by alkali fusion(NaOH: fly ash ratio 1.2:1), and dissolved of 60 using distilled water and aged of 25 for 22h. The following, at conditions of 2.2 MNaOH solution, liquid:solid=6.5, the slurry was hydrothermal crystallized at 100 for 24 h. Synthesis of particles exhibits completely grown crystals of zeolites-Y and cubic morphology with approximate dimensions of 400 mm. The crystalinity of zeolite-Y was 88.7%. At the advantage of this paper was to synthesize superfine Y zeolite that using only flyash as a raw materia and without using any other silicon and aluminum source and any template addition under mild conditions.
