The zeolite from F class coal fly ash (FA) was prepared from alkali fused fly ash
followed by hydrothermal treatment. Sodium water glass obtained from the calcined and
acid activated FA and sodium aluminate were used in zeolitization. Hydrothermal
reaction was performed at 90°C for 4h. The prepared zeolitic material was characterized
by EDX, XRD, FT-IR and Hg-porosimetry. The concentrations of the main components
SiO2, Al2O3, and Na2O in the synthesized material are: 51.45%, 30.01%, and 16.64%,
respectively. The diffraction patterns show that the characteristics lines are at 14.4°,
20.5°, 25.5°, 32.7°, 39°, and 44.5° that are typical for Na-X zeolite. The FT-IR spectra
show that the strongest vibration is at 960 cm-1 (T-O stretch), whereas the vibrations in
the region between 600 and 750 cm-1 are related to tetrahedral atoms in zeolite structure
[1, 2]. The Hg porsimetry measurements show that the porosity of obtained material is
around 62% and the total pore volume is 1,10 ...cm3/g. Such characteristics of the prepared
zeolitic material allow its use in various catalytic chemical processes for converting
vegetable oil to biofuel including transesterification, deoxygenation, thermal cracking,
catalytic cracking, and hydroprocessing.
