以氢气反应球磨法制备出储氢材料 65Mg35C,并利用储氢材料加热放出的高活性氢与噻吩发生加氢反应,采用TEM、XRD、DSC及自行设计的排水法放氢装置等对噻吩加氢反应前后的储氢材料进行性能测试及结构表征.分别研究了反应温度和反应时间对噻吩加氢反应的影响,并分析了加氢产物.结果表明,储氢材料与噻吩的加氢反应是在一定温度范围内进行的,同时也要考虑储氢材料的放氢温度,温度低于300℃或高于400℃时均不利于反应的进行;在一定温度下,储氢材料对噻吩加氢反应的时间短有利于产物H2S气体的逸出,时间过长有利于H2S和放氢后储氢材料中的高活性单质Mg发生反应;常压下,在适宜的反应温度范围内,储氢材料对噻吩具有加氢脱硫作用.%The hydrogen storage material 65Mg35C was prepared by reactive milling under hydrogen atmosphere. The hydrogen released from hydrogen-storage material to be heated was used for the hydrogenation reaction of thiophene. Property test and structure characterization of hydrogen storage material were carried out before and after thiophene hydrogenation reaction with TEM, XRD,DSC and the self-designed hydrogen release test. The influence of reaction temperature and time on thiophene hydrodesulfurization with the hydrogen storage material was analyzed, and the structure of sulfide precipitation of reaction products was characterized by XRD. The result shows that the reaction of the hydrogen storage material and thiophene hydrogenation takes place at a certain range of temperature, but when reaction temperature is lower than 300℃ or higher than 400℃ is unfavorable to the hydrogenation reaction of thiophene to convert into H2S. The shorter time of the thiophene hydrogenation reaction is favorable to the H2S conversion, and the longer time is favorable to the reaction of H2 S and high activity magnesium in hydrogen storage material after hydrogen desorption under certain temperature. At atmospheric pressure and within a cetain range of temperature, the hydrogen storage material has the function on thiophene hydrodesulfurization.
