Abstract: In order to fulfill the future world energy demand, all energy resources may need to be utilized. Despite the efforts and the commitment for renewable power to account for a significant share of the total electricity supply, coal is still one of the most important electricity producing fuels. Coal fly ash (CFA) is generated during the combustion of pulverized coal in coal fired power stations; as such it is an industrial by-product that if not put to beneficial use, is a recognized environmental pollutant. This study investigated the chemical modifications of coal fly ash treated by two steps with heat and acid treatment for the environmental applications. Modification of coal fly ash observed in this study influenced changes in property of treated fly ashes. The effect of the modification of fly ash was determined by XRD and SEM techniques.
Keywords: coal fly ash, modification, acid and heat treatment
