甲烷催化裂解制氢研究现状

Research Status of Hydrogen Production from Methane Catalytic Cracking

甲烷进行催化裂解是一种比较保护环境并且清洁的工艺,因为裂解后的产物中只有高纯度的氢气和一些碳纳米材料,没有任何污染性的气体,因此甲烷催化裂解制氢已经成为了研究的重点。文章简述了甲烷裂解制氢的反应机理,以及催化剂种类、载体种类、气体空速和反应温度对甲烷裂解的影响,并对于裂解后副产物的利用以及催化剂的失活和再生进行了说明。

Catalytic cracking of methane is a relatively environment-friendly and clean process,because there are only high-purity hydrogen and some carbon nano materials in the products after cracking,and there is no polluting gas.Therefore,catalytic cracking of methane to produce hydrogen has become the focus of research.The reaction mechanism of hydrogen production from methane cracking and the effects of catalyst type,carrier type,gas space velocity and reaction temperature on methane cracking were briefly described.The utilization of by-products after cracking and the deactivation and regeneration of catalyst were explained.
