Abstract

The mesoporous material MCM-41 has been successfully synthesised by hydrothermal method using silica sources extracted from Vietnamese bentonite and cetyltrimethyl ammonium bromide (CTAB) as template. WO3 catalyst dispersed on support of MCM- 41 by impregnation method with ammonium paratungstate hydrate. The catalytic materials were characterised by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The catalytic activity was investigated by oxidative desulfurisation reaction on model fuel oil containing dibenzothiophene (DBT), and commercial diesel. The results showed that with WO 3/MCM-41 catalyst, the oxidation of DBT to sulfoxide (DBT-O2) achieved 98.78% and the removal of commercial diesel 88.2%.
