摘要
全球能源危机的大环境促生了诸多新能源的研发,氢能是其中的重要分支。在氢能的开发利用过程中,对高纯氢的需求是一个关键课题。而在众多的氢纯化方法中,金属膜分离法最简单、有效且耗能少,钯合金也因在氢纯化上表现出的优异性能而受到广泛关注。本文对钯合金在氢纯化领域的应用进行了介绍,同时对应用过程中不可避免的杂质气体毒化效应及其研究现状进行了综述。杂质气体毒化会显著降低膜材料的性能,是制约其工程应用可靠性的重要问题。本文通过对相关研究现状的分析,揭示了目前存在的缺乏毒化后相应恢复技术研究等不足,并提出了后续可以重点关注的方向。
The situation of global energy crisis has spurred the development of various new energy,with hydrogen energy being a major branch.And the demand for high-purity hydrogen is the key issue during the utilization of hydrogen energy.Among the numerous hydrogen purification methods,metal membrane separation stands out as the simplest,most effective,and energy-efficient approach,while palladium alloys have attracted widespread attention due to their exceptional performance in hydrogen purification.This paper provides an overview of the application of palladium alloys in the field of hydrogen purification,along with a review of the inevitable impurity gas poisoning effects during this application and the current research status.Impurity gas poisoning degrades the performance of membrane materials significantly,posing a critical challenge to the reliability of their engineering applications.This paper highlights existing shortcomings through an analysis of the current research landscape,such as the lack of studies on post-poisoning recovery techniques,and suggests potential aspects for future research focus.
