Summary: | The invention discloses a biomass gasification hydrogen-producing system and a method, which belongs to the technical field of hydrogen production. Biomass gasification hydrogen production and chemical-looping combustion are combined to realize low-cost separation of carbon dioxide; and the fractional utilization of matter and energy is realized via the circulation among three beds with metal oxide as a heat carrier and an oxygen carrier. The system mainly comprises an air reactor, a fuel reactor, a moving bed gasifier, a gas-solid separation device, a gas purification device, a hydrogen separation device and a follow-up hydrogen-producing device. The system not only can realize hydrogen production, but also can realize hydrogen production with near zero emission of CO2, thereby realizing efficient cleaning and utilization of biomass. |
