| 摘要 |
The invention relates to a method for generating hydrogen by means of a reaction with aluminum, based on reacting aluminium with water in a hydroxide solution, comprising the addition of alcohol as a solvent to the solution. The alcohol is of the type having a lower density, higher vaporisation temperature and lower reactivity, preferably isopropanol, ethanol or bioethanol. The reactor is first filled with aluminium and, subsequently, the alcohol is added so that the reactor is completely full. Part of the alcohol is then emptied such that it only covers the aluminium, with the rest of the space being emptied. The hydroxide solution is then metered according to the hydrogen demand. The hydrogen and the alcohol vapour generated are distilled in an exchanger. The distilled alcohol is returned to the reactor and the hydrogen is filtered and stored. |
