Characterization of X-type Zeolite Prepared from Coal Fly Ash
This study presents experimental results dealing with the possibility of transforming F-class fly ash into a zeolitic material. Two types of synthesis methods were used in the research: hydrothermal and low-temperature synthesis. As a result of alkaline reaction of fly ash with NaOH, all experimental cases yielded zeolitic material that are rich in a Na-X phase. The mineralogical composition (d...
متن کاملSynthesis and characterization of zeolites prepared from industrial fly ash
In this paper, we present the possibility of using fly ash to produce synthetic zeolites. The synthesis class F fly ash from the Stalowa Wola SA heat and power plant was subjected to 24 h hydrothermal reaction with sodium hydroxide. Depending on the reaction conditions, three types of synthetic zeolites were formed: Na-X (20 g fly ash, 0.5 dm(3) of 3 mol · dm(-3) NaOH, 75 °C), Na-P1 (20 g fly a...
متن کاملSilica Reduction Technology for Fly Ash Zeolite Synthesis
The increasing requirements for the environmental protection have resulted in the search for more effective, inexpensive and ecologically safe solutions. Zeolite is one of the alternatives, which due to their peculiar structure are widely used for various environmental processes. The demand for an easily accessible and inexpensive source of zeolite has raised interest in synthesis of these mine...
متن کاملImidazolium Chloride Immobilized Fly Ash as a Heterogenized Organocatalyst for Esterification Reaction under Microwave Irradiation Heating
An efficient solventless one-pot procedure for the synthesis of imidazolium-based ionic liquid under microwave irradiation is described in which 1-methylimidazole was modified by organosilane (3-chloropropyl triethoxysilane). This ionic liquid 1-methyl-3-[(triethoxysilyl)propyl]imidazolium chloride (TMICl) is immobilized on Mechanically activated Fly Ash (MFA) by co-condensation method to d...
متن کاملAdsorption of tungsten onto zeolite fly ash produced by hydrothermally treating fly ash in alkaline solution.
Fly ash (FA) was hydrothermally treated in an alkaline solution to produce zeolite fly ash (Z-FA). The properties of the FA and Z-FA were investigated. The amounts of tungsten (W) adsorbed onto the FA and Z-FA surfaces were evaluated. Z-FA was produced by hydrothermally treating FA in an alkaline solution. The specific surface area and pore volume of the Z-FA were greater than those of the FA. ...
