Zeolite Synthesis from Coal Ash and Refuse Incineration Ash of Circulating Fluidized Bed Combustor

Abstract

Zeolite synthesis from the coal ash and refuse incineration ash of circulating fluidized bed combustor (CFBC) was investigated to reuse the ashes effectively. In this study, zeolite was synthesized by hydrothermal alkali reaction. Evaluation for the possibility of zeolite synthesis from the ashes was performed by XRD analysis, SEM photograph and the capacity of ammonium ion absorption. The possibility for reuse and recycle of ashes was discussed by comparison between the coal ash and refuse incineration ash of circulating fluidized bed combustor.
