Abstrakt: The research investigated the efficiency of zeolitization of silicon and alumina bearing combustion by-products, i.e. coal fly ash and coal microspheres. Lab-scale alkali activation with 3M sodium hydroxide solution of raw materials obtained from a Polish coal-fired power plant were conducted at 100 °C. The obtained result proved that both combustion by-products are prone to zeolitization under the tested conditions with the obtained zeolite yields of 60 and 55% in the case of fly ash and microspheres, respectively. The main identified zeolite in the case of both by-products was NaP1. [ABSTRACT FROM AUTHOR]
