摘　　要：甲基环己烷(MCH)因具有较高的理论储氢量以及优越的理化性质而被认为是最具有应用前景的有机液体储氢材料,甲基环己烷-甲苯-氢(MTH)循环实现了材料和能源的循环利用,具有良好的工业应用前景。然而,MCH催化脱氢过程所使用的催化剂因其低温活性欠佳及高温不稳定的问题导致MTH循环无法大规模应用。为解决该问题,前人已进行了广泛的研究,发现催化剂的设计是解决该问题的核心。综述MCH脱氢催化剂的现状,重点阐述单、双和三金属催化剂的研究进展以及各自的优缺点,分析活性组分、载体和助剂的协同作用对催化剂的影响,展望未来催化剂的研究方向。基于现有分析认为,在未来的研究中添加第二金属、调节催化剂载体的性质和使用Ni金属作为活性组分,以获得高稳定性、高活性和低成本的MCH脱氢催化剂,可以满足商业化应用的要求。Methylcyclohexane(MCH)is considered to be the most promising organic liquid hydrogen storage material with high theoretical hydrogen storage capacity and superior physical and chemical properties.The Methylcyclohexane-Toluene-Hydrogen(MTH)cycle realizes the cycle utilization of materials and energy,which has good industrial application prospects.However,the MTH cycle can not be used on a large scale because of the catalyst used in the dehydrogenation of MCH has poor activity at low temperature and instability at high temperature.In order to solve this problem,previous researchers have carried out extensive research and found that the design of catalyst is the core of solving this problem.In view of this,the current situation of MCH dehydrogenation catalysts were reviewed,the research progress,advantages and disadvantages of mono-,bi-and tri-metal catalysts were introduced with emphasis,the influence of the synergistic effect of active component,support and promoter on the catalysts were analyzed,and the future research directions of catalysts was prospected.Based on the existing analysis,it is believed that adding a second metal element,adjusting the properties of the catalyst support and using Ni metal as the active component can obtain high stability,high activity and low cost MCH dehydrogenation catalyst in the future studies to meet requirements of commercial applications.
