Abstract
A dry hydrogen production device includes: a reactor to which water or vapor is not supplied; heating means configured to heat the reactor to 200 to 800° C.; a supply line for hydroxide of at least one of alkali and alkali earth connected to the reactor; a biomass supply line connected to the reactor; at least one carrier gas supply line connected to the reactor; a gas phase reaction product outflow line connected to the reactor, a solid-gas separator connected to the gas phase reaction product outflow line; and a gas separator connected to the solid-gas separator.
Claims24
A dry hydrogen production device, the device comprising:
- a reactor to which water or vapor is not supplied;
- heating means configured to heat the reactor to 200 to 800° C.;
- a supply line for hydroxide of at least one of alkali and alkali earth connected to the reactor;
- a biomass supply line connected to the reactor;
- at least one carrier gas supply line connected to the reactor;
- a gas phase reaction product outflow line connected to the reactor;
- a solid-gas separator connected to the gas phase reaction product outflow line;
- and
- a gas separator connected to the solid-gas separator.
A dry hydrogen production method, the method comprising steps of:
- loading hydroxide of at least one of alkali and alkali earth into the reactor;
- supplying biomass to the reactor;
- producing a reaction product by heating the reactor to 200-800° C. without supplying water or vapor, while supplying carrier gas to fluidize a hydroxide and biomass mixture in the reactor;
- discharging a produced gas phase reaction product from the reactor;
- separating the gas phase reaction product into a gas effluent and a solid effluent through solid-gas separation;
- and
- producing a gas product through gas-gas separation from the gas effluent.
