| Abstract |
The conversion of vegetable oil has been investigated using NiW modified with different SiO2/Al2O3 ratios nanocrystalline ZSM-5 zeolites as catalysts in the hydrocracking of palm oil. ZSM-5 zeolites were synthesized from natural kaolin from Lampang province, Thailand, via the hydrothermal process. Kaolin was calcined at 700 °C for 3 h and followed by digestion with 3 M HCl before used. The chemical composition of SiO2 and Al2O3 analyzed by X-ray fluorescence spectrometry (XRF) were 72.74 %wt and 21.22 %wt, respectively. In preparation of ZSM-5 zeolites, the SiO2/Al2O3 mole ratios were adjusted to 30, 50, 70 and 100 by adding Na2Si3O7 solution. Additionally, the tetrapropylammonium bromide (TPA-Br) was used as a templating agent. The optimum conditions of ZSM-5 zeolite synthesis for hydrothermal process were 170 °C and the reaction time for 24 h. After that, the synthesized products for the ion-exchange process were refluxed with 1 M (NH4)2SO4 at 90 °C for 2 h and then calcined at 550 °C for 3 h. Subsequently, the ZSM-5 zeolites were characterized by x-ray diffraction spectrometry (XRD), fourier transform infrared spectrometry (FT-IR), scanning electron microscope (SEM), Transmission electron microscope (TEM) and brunauer-emmett-teller (BET) surface area analysis. The zeolite supported NiW catalysts were prepared employing the impregnation technique and then calcined at 550 °C for 3 h. The NiW/ZSM-5 catalysts were tested in the hydrocracking of palm oil , which showed the catalytic activity compared to ZSM-5 obtained commercially. |
