  • Hybrid dehydrogenation reaction system
    Patent number: 11594744
    Abstract: A hybrid dehydrogenation reaction system includes: an acid aqueous solution tank having an acid aqueous solution; an exothermic dehydrogenation reactor including a chemical hydride of a solid state and receiving the acid aqueous solution from the acid aqueous solution tank for an exothermic dehydrogenation reaction of the chemical hydride and the acid aqueous solution to generate hydrogen; an LOHC tank including a liquid organic hydrogen carrier (LOHC); and an endothermic dehydrogenation reactor receiving the liquid organic hydrogen carrier from the LOHC tank and generating hydrogen through an endothermic dehydrogenation reaction of the liquid organic hydrogen carrier by using heat generated from the exothermic dehydrogenation reactor.

  • METHOD FOR GENERATING HYDROGEN
    Publication number: 20220250903
    Abstract: A hydrogen generating method includes generating hydrogen by dehydrogenation-reacting a chemical hydride of a solid state with an acid aqueous solution. The dehydrogenation-reaction is performed by reacting 1 mol of hydrogen atoms of the chemical hydride with an acid and water at a molar ratio of 0.5 to 2.
