摘    要:氢能是理想的能源载体,活性金属分解水制氢具有固态含能、现场制氢、按需供氢,且对水质要求低等特点。本文从Al/H2O反应热力学和动力学两方面综述了铝合金活化的共性问题;从影响Al/H2O反应的内因和外因等因素归纳了活性铝工程化的可行途径。采用多元合金化和合适的制备工艺是活化铝的有效途径;活性铝制氢技术工程化应用的潜力与突破是极端环境。此外,指出Al/H2O自发反应的预判性研究、可持续反应的定量性研究、产业化中产物的循环再利用问题等是活性Al制氢技术进一步发展的方向。最终实现成本低廉、环境友好、安全可靠的活性铝分解水制氢技术的工业化应用。

关 键 词:Al  氢气  分解水  热力学  动力学

Abstract:Hydrogen energy is an ideal energy carrier. Hydrogen production from activated metal splitting water has the characteristics of solid-state containing energy, in-situ hydrogen production, supplied hydrogen on demand, and lower requirements for water quality. In this paper, the common problems of activated aluminum alloy are reviewed from the thermodynamics and the kinetics of Al/H2O reaction, and the feasible methods of engineering applied are summarized from the internal factors and the external factors affecting Al/H2O reaction. The key issue of activated aluminum is to adopt multi-element alloying and suitable fabrication processing, and the potential and outbreak of the engineering application of Al/H2O reaction is extreme environment. Moreover, it is pointed out that the predictive investigation and the quantitative investigation of Al/H2O spontaneous reaction, the recycling of Al/H2O reaction products in industrialization are the further development direction. Finally, the industrial application of hydrogen produced by activated aluminum splitting water is low-cost, environment-friendly, safe and reliable.
Keywords:Aluminum  hydrogen  splitting water  thermodynamics  kinetics
