甲基环己烷(MCH)作为最佳的液态有机氢化物储氢介质,是甲基环己烷-甲基-氢气(MTH)循环体系中的重要组成部分,但MCH催化脱氢过程所使用催化剂因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。本文综述了MTH循环系统的应用现状和该系统中MCH脱氢过程催化剂的研究现状。重点概述了单、双金属催化剂设计现状,比较了不同催化剂性能的优劣。此外,还比较了各类催化剂释氢速率以及反应条件和催化反应器结构特点。分析表明,研发出低温高活性或高温高稳定性的催化剂有利于MCH脱氢过程;此外,开发出既能打破反应平衡限制又能强化传质和传热效果以及保持催化剂稳定性的车载催化反应器将会加速MT...

As the best liquid organic hydrides medium,methylcyclohexane is very important in the MTH circulation system. But the catalyst used in catalytic dehydrogenation process of MCH has the problems of the poor activity at low temperature and instability at high temperature,which limited the MTH circulation for large-scale application. This paper reviews the applications of MTH system and the research status about different kinds of catalysts applied in the process of the methylcyclohexane dehydrogenation. It also summarizes the design of the single and double metal catalysts and compares the perfor...
