【Abstract】 After pure phase γ Mo 2N has been synthesized,catalysts with Mo nitride on TiO 2 and Al 2O 3 were prepared,respectively.Their crystalline structures were determined by using X ray diffraction(XRD).Hydrodesulfurization activities and reaction kinetics of these catalysts were studied by microreactor equipped with a gas chromatography.Hydrodesulfurization catalytic activities of TiO 2 supported Mo nitrides,Al 2O 3 supported Mo nitrides and TiO 2 supported Co,Mo commercial hydrodesulfurization catalysts were examined at varies pretreatment conditions.更多还原
