Fabrication of Nano Zeolite P from Coal Fly Ash by Combining Alkaline — Fusion and Hydrothermal Reactions

Abstract:

Well-crystallised nanozeolite P has been synthesized from coal fly ash by combined method of alkaline-fusion and hydrothermal reactions. The influence of preparation parameters, such as the proportion of fly ash/NaOH, the hydrothermal reaction temperature and time on the reaction products were investigated by XRD and FESEM. Results indicated that, the optimum conditions for fabrication of a single phase of zeolite P were the mass ratio of fly ash/ NaOH =1/1, fusion temperature at 550°C and hydrothermal temperature at 100°C for 48h .The average crystallite sizes of the zeolite samples are 29.4nm. The obtained products show crystal morphology heterogeneity comprised by various euhedral forms.
