摘要
铝水解制氢是一种很有发展前景的储存和运输氢能的方式。文章考察了生石灰(CaO)添加量、添加方式及添加剂NaCl等影响因素对铝水解产氢性能的影响,并结合XRD进行分析。结果表明:CaO提供的碱性环境可促进铝水解反应产氢,随着CaO量的增加,促进作用增强,铝水解反应完全,氢产量增大;将CaO与铝粉制成铝粉包投入水中,CaO更有利于铝水解反应产氢;铝粉包中添加粉包总质量9%的NaCl,可加快铝水解快速反应速度并延长快速反应时间,氢产量明显增加,与未添加NaCl相比,氢产量增加64.8%。
Aluminum-water reaction is a quick and effective technology for hydrogen production, and was considered as a promising way for storage and transportation of hydrogen. The effect of quicklime（CaO） addition amount, addition manner and additive NaCl on the characteristics of hydrogen production from aluminum-water reaction was studied. The experimental results show that CaO promotes aluminum-water reaction for hydrogen production due to quicklime provide a basic alkaline environment and as reaction catalyst. With the CaO amount increasing, promoting effect on aluminum-water reaction is enhanced, hydrogen yield increase. When aluminum and quicklime is made into the mineral bag, the quicklime is more advantageous to aluminum-water reaction for hydrogen production. The reaction will be speed up when addiing 9% NaCl of the total mass. The hydrogen yield increased significantly, Compared with not adding NaCl, the hydrogen yield ratio increased to 64.8%.
