    (Maltepe Üniversitesi, 2017) Korkut, Ece; Kurt, Gizem; Mermer, Nevin Karamahmut; Demircan, Yasemin Şengün; Ünen, Hüseyin Can
    Coal fly ash is one of the important Si and Al source for the synthesis of microporous aluminosiliceous minerals known as zeolites. Zeolites are present in our everyday life, being widely used as sorbents, as ion exchangers in detergents, or as catalysts in industrial processes. ln the last few decades, lots of synthesis methods has been improved to obtain zeolites from fly ash. ln this study, 4A and X zeolite blend was synthesized by indirect method from coal fly ash. The purpose of these experiments are to investigate whether there is any effect on the synthesized zeolite of the pretreatment process that consist of sieving, calcination and HCl leaching...
