The physico-chemical properties of NiW/TiO 2-Al 2O 3 catalyst prepared by microwave irradiation and its catalytic performance for hydrodesulfurization of thiophene were studied and compared with NiW/TiO 2-Al 2O 3 catalyst prepared by normal impregnation. The TiO 2-Al 2O 3 mixed oxide was prepared by microwave irradiation and normal impregnation by using TiCl 4 as the precursor. The active component WO 3 and the promoter NiO were supported by microwave irradiation and normal successive impregnati...
