Abstract: Magnesium-based hydrogen-storage material was prepared by reactive ball-milling under hydrogen atmosphere, and then the hydrogen-storage material was utilized for the hydrogenation reaction of thiophene to convert into H2S with the hydrogen released from the material. The effect of reaction atmosphere H2, N2, CO2 and Ar on the reaction between hydrogen-storage material and thiophene was investigated. It was shown that the hydrogen-storage material made thiophene hydrogenated under one of the four kinds of atmosphere of normal pressure at 350℃. The MgH2 in the hydrogen-storage material released hydrogen and the magnesium reacted with sulfur to convert into MgS after reaction under the atmospheres except high pressure hydrogen. The hydrogen-storage material maintained MgH2 and magnesium did not react with sulfur under 1MPa hydrogen atmosphere. The N2 and CO2 in reaction atmosphere did not react with magnesium in the hydrogen- storage material.
