"A series of NiW/ c-Al2O3 catalysts (20 and 30 wt% W and 1\u20135 wt% Ni) have been prepared and studied by TPR and XPS. HDS activity has been tested in the thiophene conversion. The e?ect of Ni and W loadings on the formation of di?erent structures is presented. In the calcined catalysts several phases coexist, concentrations of which depend on the Ni/(Ni+W) atomic ratio. The Ni synergistic e?ect in the HDS reaction is con?rmed by the increase in the HDS activity ( 10\u201315 times). This e?ect is ascribed to the formation of an active NiWS phase of high dispersion from the mixed NiW oxide precursors. At higher Ni/Ni+W ratio a redistribution of active components in additional amount ofNiWS phase during sul?dation is suggested." .
