Study of hydrogen generation by hydrolysis of aluminum in NaOH solution

在旋转磁场条件下,驱动磁针可产生高频碰撞状态。根据该理论,提出一种铝粉在磁针碰撞研磨条件下水解制备氢气的新方法;考察了铝粉粒径、磁场转速以及催化组分选择等因素对铝-碱水解速率的影响。实验结果表明,在磁力研磨条件下,可实现工业铝粉与碱液水解快速制取氢气;可为燃料电池提供纯净氢气,实现现场制氢、供氢,有效解决氢气储存问题。

The driving magnetic needle can reach high-frequency collision in rotating magnetic field.A novel method of hydrogen preparation by the hydrolysis of aluminum powder based on the theory was investigated.The effects of aluminum particle size,rotate speed of the magnetic field and catalyst components on the hydrolysis rate of aluminum in alkaline solution were studied.The results show that under this condition,hydrogen can be produced quickly by the hydrolysis of industrial aluminum powder in alkaline solution,which can provide hydrogen with non-toxic gases for fuel cells with this technique,actualize the production and supply of hydrogen on the spot and solve the problem of hydrogen storage effectively.
