A decalin dehydrogenation/Naphthalene hydrogenation pair has been proposed as a effective hydrogen carrier, in which catalytic decalin dehydrogeno-aromatization takes an essential role under reactive distillation conditions with waste heats (around 200℃) Carbon-supported platinum-based catalysts in the liquid-film states gave one-pass conversions of decalin into hydrogen and naphthalene, exceeding the limit of chemica equilibrium with irrespective of naphthalene content in the decalin solution. In this paper we emphasized the advantages of this decalin/naphthalene system for long-term storag and long-distance transportation of hydrogen superior to other systems from the viewpoints of hydrogen contents and required exergies.
