This study presents a technological line prototype, on the basis of which it is possible to obtain the zeolite materials based on hydrothermal reaction of fly ashes with sodium hydroxide. This technological solution allows to obtain three types of zeolite products: Na-P1 type, mixture of Na-P1/Linde-A and mixture of Na-P1/Linde-A/Na-X. the final product is dependent on the parameters of the synthesis process. The resulting zeolite materials, in relation to the fly ash, had much better surface/sorption properties, which are crucial for the potential application in environmental engineering.
These materials can be used in:
Removal of hydrocarbon substances,
Removal of heavy metal ions from waste water,
Removal of radionuclides from mine water.
Fly ashes, which are waste materials, can be applied in the synthesis of low cost zeolites, whose chemical, morphological and textural properties are promising from the environmental protection point of view.
