Study of the parameters of zeolites synthesis from coal fly ash in order to optimize their CO2 adsorption
The coal fly ash (CFA) from a coal gasification plant was used as raw materials for X zeolites synthesis by fusion and hydrothermal method and the ability of CFA-derived zeolites to adsorb CO2 was studied. After characterization of CFA, factors affecting the synthesis of different zeolites from this CFA, i.e., NaOH/CFA weight ratio, crystallization temperature and crystallization time were investigated.
