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.
Methane pyrolysis hydrogen production has the characteristics of high hydrogen purity and clean pollution-free, is considered to be one of the most promising methods of hydrogen production at this stage of methane cracking hydrogen production research focused on the preparation of both activity and stability Catalyst.We reviewed the progress of two series catalysts of carbonaceous catalyst and metallo catalyst in the hydrogen cracking reaction of methane cracking in recent years.The effects of the catalyst, active components and additives on the hydrogen production performance of the cracked methane were investigated The system analysis was summarized and the reaction mechanism and the deactivation and regeneration of the catalyst were summarized. Based on the above, the future development trend of the catalyst was prospected.
