摘要
甲烷裂解制氢方法具有产氢纯度高和清洁无污染的特点,被认为是当前最有前景的制氢方法之一.现阶段甲烷裂解制氢的研究工作主要集中于制备活性与稳定性兼备的催化剂.我们综述了近年来甲烷裂解制氢反应中碳质催化剂和金属催化剂两大系列催化剂的研究进展,从载体、活性组分、助剂3个方法对目前催化剂裂解甲烷产氢性能的影响进行了系统分析,总结了反应机理和催化剂的失活与再生情况,在以上基础上对催化剂未来的发展趋势进行了展望.
Thermocatalytic decomposition of methane is a promising method for hydrogen production due to the high yield towards hydrogen and no pollution produced. To date, the research and developments on thermocatalytic de- composition of methane mainly have been focusing on the preparation of the catalysts with high performance and sta- bility. This article has covered the recent developments of the carbonaceous and metal catalysts for thermocatalytic decomposition of methane, and discussed the relationship among the catalyst activities and the supporters, active phase, promoters of catalyst. The review summarized the reaction mechanism and the regeneration method of used catalyst yet, and have a perspective about its development trend.
