摘      要：This work describes the synthesis of catalysts based on red mud/polyethylene terephthalate（PET） composites and their subsequent heat treatment under N2 *** materials were characterized by scanning electron microscopy（SEM）,temperature programmed reduction（TPR）,Fourier transform infrared spectroscopy（FT–IR）,X-ray diffraction（XRD）,thermogravimetric（TG） analysis and N2adsorption/*** catalysts were evaluated in the oxidative desulfurization reaction of dibenzothiophene（DBT） in a biphasic *** results indicated that the PET impregnation on red mud increased the affinity of the catalyst with the nonpolar phase（fuel）,in which the contaminant was dissolved,allowing a higher conversion（up to 80%） and selectivity to the corresponding dibenzothiophene *** sulfone compound is more polar than DBT and diffused into the polar solvent as indicated by the data obtained via gas chromatography–mass spectrometry（GC–MS）.
