  • Process and apparatus for generating hydrogen
    Publication number: 20120027643
    Abstract: A solution is to be created, with a method and a device for generating hydrogen, in which silicon and/or an alloy that contains silicon is reacted in a reaction vessel (1), with an alkaline solution as a catalyst, so that the process, after starting, runs continuously and catalytically in the presence of silicon dioxide as a nucleating agent, without further addition of lye and without using higher pressures and temperatures (hydrothermal conditions). This is achieved in that the alkaline solution is used in a strongly sub-stoichiometric amount with reference to the entire reaction, whereby the silicon dioxide that is formed is precipitated onto crystallization nuclei.
    Type: Application
