NOVELTY - A storage transit system of hydrogen (S1) has hydrogen storage system (S2) having hydrogenation reactor (1) and hydrogenated aromatic compound transport unit (3), hydrogen supply system (S3) having dehydrogenation apparatus (2), recovered aromatic compound transport unit (4), and reaction inhibitor removal apparatus (1a). Reactor (1) performs hydrogenation of aromatic compound and produces hydrogenated aromatic compound. Apparatus (2) dehydrogenates hydrogenated aromatic compound and produces hydrogen and aromatic compound by organic chemical hydride method.    USE - As storage transit system of hydrogen.    ADVANTAGE - The storage transit system of hydrogen has high hydrogen storage efficiency, and carries out dehydrogenation of hydrogenated aromatic compound steadily over long period.    DETAILED DESCRIPTION - A storage transit system of hydrogen (S1) has a hydrogen storage system (S2) having a hydrogenation reactor (1) and a hydrogenation aromatic compound transport unit (3), a hydrogen supply system (S3) having a dehydrogenation apparatus (2), a recovered aromatic compound transport unit (4), and a reaction inhibitor removal apparatus (1a). The hydrogenation reactor performs hydrogenation reaction of aromatic compound and manufactures hydrogenated aromatic compound. The hydrogenation aromatic compound transport unit conveys obtained hydrogenated aromatic compound to hydrogen utilization place. The dehydrogenation apparatus dehydrogenates hydrogenated aromatic compound and reduces hydrogen and aromatic compound by organic chemical hydride method. The aromatic compound recovery unit recovers aromatic compound and transports to hydrogen storage system for preparing hydrogenated aromatic compound. The reaction inhibitor removal apparatus removes reaction inhibitor which inhibits dehydrogenation and/or hydrogenation reaction and poisoning substance of hydrogenation catalyst and/or dehydrogenation catalyst, and maintains reaction inhibitor concentration of the system within tolerance level.
