An innovative environment-friendly hydrolysis process for recycling waste aluminum with the generation of high-pressure hydrogen has been proposed and experimentally validated. The effect of the concentration of sodium hydroxide solution on hydrogen generation rate was mainly examined. In the experiments, distilled water and aluminum powder were placed in the pressure-resistance reactor made of Hastelloy, and was compressed to a desired constant water pressure using a liquid pump. The sodium hydroxide solution was supplied by liquid pump with different concentrations (from 1.0 to 5.0 mol/dm3) at a constant flow rate into the reactor by replacing the distilled water and the rate of hydrogen generated was measured simultaneously. The liquid temperature in the reactor increased due to the exothermic reaction. Therefore, a high-pressure hydrogen was generated at room temperature by mixing waste aluminum and sodium hydroxide solution. As the hydrogen compressor used in this process consumes less energy than the conventional one, the generation of hydrogen having a pressure of almost 30 MPa was experimentally validated together with aluminum hydroxide a useful by-product.

提出了一种新的高压氢气水解法回收废铝的环保工艺，并进行了实验验证。主要考察了氢氧化钠溶液浓度对产氢速率的影响。在实验中，将蒸馏水和铝粉末置于由哈氏合金制成的耐压反应器中，并使用液体泵将其压缩至所需的恒定水压。通过液体泵以恒定流速将不同浓度（1.0 - 5.0mol/dm 3）的氢氧化钠溶液通过替换蒸馏水供应到反应器中，并同时测量氢气产生速率。反应器中的液体温度由于放热反应而升高。因此，通过混合废铝和氢氧化钠溶液在室温下产生高压氢气。由于在该方法中使用的氢气压缩机消耗的能量比常规压缩机少，因此实验验证了具有几乎30 MPa压力的氢气的产生以及有用的副产物氢氧化铝。
