Abstract
(EN)
A method for producing hydrogen involving contacting steam or a gas containing steam with iron or an iron oxide, wherein the iron or the iron oxide is added with at least one metal of Rh, Ir, Ru, Pd, Pt and Os and at least one metal of Ti, Zr, V, Nb, Cr, Mo, Al, Ga, Mg, Sc, Ni and Cu. The method provides a medium for generating hydrogen which is capable of generating hydrogen at a relatively low temperature and at a great generation rate, is free from the decrease of activity, and is resistant to repeated oxidation and reduction, which leads to the decomposition of water and production of hydrogen with good efficiency.
(FR)
La présente invention concerne un procédé pour produire de l'hydrogène comprenant la mise en contact de vapeur ou d'un gaz contenant de la vapeur avec du fer ou un oxyde de fer, le fer ou l'oxyde de fer étant ajouté à au moins un métal choisi parmi Rh, Ir, Ru, Pd, Pt et Os et à au moins un métal choisi parmi Ti, Zr, V, Nb, Cr, Mo, Al, Ga, Mg, Sc, Ni et Cu. Le procédé représente un moyen de produire de l'hydrogène qui rend possible une production d'hydrogène à température relativement basse et à débit de production élevé, n'est pas sujet aux baisses d'activité, et résiste aux oxydations et réductions répétées, ce qui mène à la décomposition d'eau et à une production d'hydrogène avec un bon rendement.
