Long-term Storage and Long-distance Transportation of Hydrogen by Use of Catalyst-assisted Decalin Dehydrogenation/ Naphthalene Hydrogenation Pair

Abstract

Taking into account of the well-established commercial process of naphthalene perhydrogenation to decalin, endothermic catalysis of decalin dehydrogeno-aromatization has been investigated under mild reaction conditions (200～210℃, 1atm), with a carbon-supported platinum-tungsten composite catalyst revealed to be active for hydrogen evolution from decalin to naphthalene under boiling and refluxing conditions. A new approach for economical long-distance transportation or long-term storage of hydrogen is discussed on this basis.
