Preparation of Zeolitic Compounds From High Calcium Fly Ash
Various zeotttic compounds such as faujasite-Na and sodium aluminum silicate hydrate have been synthesized from high calcium fly ash by a classical hydrothermal treatment. The composition of reaction mixtures was set with a Si:A ratio of I by adding a transition alumina to the fly ashes. NaOH solutions with 2 and 4 molar concentrations were used to dissolve the aluminosilicates in the fly ash and produce the conditions for zeolite crystallization. Zeolitic compounds have been prepared at 150℃and 200℃ temperatures for 4-24 hrs.
