Sol-gel auto combustion synthesis of BaFe18O27 nanostructures for adsorptive desulfurization of liquid fuels
In this work, for the first time, W-type barium ferrite nanostructures (BaFe18O27) were synthesized by sol gel auto combustion method. The role of the calcination temperature and the type of sugar were investigated on the basis of their morphology and the size of the particles. The obtained products were characterized by Electron microscopy (EM), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and energy dispersive spectrometry (EDS) and vibrating sample magnetometer (VSM). Adsorptive desulfurization (ADS) is one of the most promising complementary and alternative methods. To evaluate the ADS reactivity over the W-ferrite, a series of ADS experiments with a model gasoline feedstock were performed using a fixed-bed reactor. The results of catalytic tests reveals that BaFe18O27 nanoparticles have the potential to be used as a new absorptive for desulfurization of liquid fuels. 0.5 g BaFe18O27 exhibited the highest ADS properties. This ferrite was successfully regenerated after calcining at 500 degrees C in air. (c) 2017 Hydrogen Energy Publications LLC. Published by Elsevier Ltd. All rights reserved.
