| 摘要 | A method for the preparation of zeolites from non-fused fly ash includes the steps of preparing an aqueous alkali hydroxyl solution and mixing the solution with the non-fused fly ash to create an aqueous alkali hydroxyl fly ash mixture, subjecting the mixture to ultrasonication and recovering the zeolites. The method may include the step of centrifuging the aqueous alkali hydroxyl fly ash mixture and washing the solid synthetic products (zeolites). | ||

| 主权项 | 1. A method for the preparation of zeolites from non-fused fly ash, the method comprising the steps of preparing an aqueous alkali hydroxyl solution, mixing the solution with the non-fused fly ash to create an aqueous alkali hydroxyl fly ash mixture, subjecting the mixture to direct ultrasonication, and recovering the zeolites, wherein said method does not comprise an additional hydrothermal process step and wherein the direct ultrasonication is conducted at between 18° C. and 25° C. | ||
