Zusammenfassung:The present invention is a process for the obtention of a hydrogen-rich gas stream from aluminium waste comprising obtaining a process water resulting from contacting aluminium salt slag with tap water, adding the process water of the previous step to an aluminium waste in a solution, and the hydrolysis of that solution to obtain the gas stream. The process is capable to obtain a yield of reaction close to 100% in higher reaction times.
