ABSTRACT |
Coal fly ash generated from power plants is continuously increasing each year in Korea. Only small portion of the fly ash is utilized, and the rest of them is disposed as landfills which causes a serious environmental problem due to toxic trace elements. In this study, the conversion of coal fly ash to various type of zeolite (cancrinite, X, P) was investigated as an other application area of coal fly ash utilizations.
The conversion conditions from coal fly ash to the various types of zeolites depend on the many parameters, such as chemical composition of coal fly ash and curing time. Therefore, in this study the proper conditions necessary to form various types of zeolites from coal fly ash were investigated.
