System and method for hydrogen production by dehydrogenation of formic acid

A system for hydrogen production by dehydrogenation of formic acid (HCOOH), said system comprising:

• a reactor vessel comprising a reactor space bound by a reactor wall, wherein said reactor vessel is arranged for holding a mixture of a catalyst and said formic acid in said reactor space, said reactor vessel further comprising a mixture inflow opening for allowing said mixture to enter, via said mixture inflow opening, said reactor space and a mixture outflow opening for allowing said mixture to exit, via said mixture outflow opening, said reactor space, and a gas outflow opening for allowing hydrogen originating from said mixture, via said gas outflow opening, to exit said reactor space;
• an inflow conduit, communicatively coupled for fluid flow, via said mixture inflow opening, to said reactor space;
• a pump, communicatively coupled for fluid flow, via said mixture inflow opening and said mixture outflow opening, to said reactor space, wherein said pump is arranged for withdrawing, via said mixture outlet opening, said mixture from said reactor space and introducing, via said inflow conduit, said mixture into said reactor space;
• and
• a temperature control arrangement, communicatively coupled for fluid flow to said pump, wherein said temperature control arrangement is arranged outside the reactor space for heating and/or cooling, in use, said mixture withdrawn from said reactor space to a predetermined temperature range before introducing, via said inflow conduit, said mixture into said reactor space,
• wherein said reactor wall comprises at least one of:
• a polymer;
• a coating arranged for thermally insulating said reactor vessel and/or shielding said mixture from predetermined materials;
• and
• replaceable wall elements arranged for realising a locally reinforced surface, and/or
• wherein said reactor vessel comprises at least one of:
• an upper side wall, wherein said upper side wall at least partly bounds said reactor space at an upper side thereof, wherein said upper side wall is provided with said gas outflow opening for allowing hydrogen originating from said mixture to exit, via said gas outflow opening, said reactor space;
• and
• a lower side wall, wherein said lower side wall at least partly bounds said reactor space at a lower side thereof, wherein said mixture outflow opening is provided in said lower side wall.

• said inflow conduit is arranged such that said mixture, in use, is introduced in said reactor space, via said mixture inflow opening, in a predetermined direction having a tangential component arranged for stirring, in use, said mixture in said reactor space;
• said system further comprises a stationary flow organ arranged in said reactor space for disturbing a flow of stirring, in use, induced by introduction of said mixture in said reactor space via said inflow conduit, in said reactor space
• said reactor vessel or said inflow conduit is provided with a further inflow opening arranged for introducing said formic acid in said reactor vessel;
• and
• said reactor vessel is free from a mechanical stirrer.
