Abstract

The invention discloses a method and an apparatus for producing hydrogen from bio-oil in chained mode and separating CO2. The method comprises: pre-placing Fe2O3 in a moving-bed reactor, spraying the bio-oil from the central part of the moving-bed reactor to perform a cleavage reaction in the moving bed for generation of H2, CO, micromolecular hydrocarbons and solid carbon, reducing Fe2O3 with H2, CO and the micromolecular hydrocarbons and generating CO2, vapour and FeO, depositing solid carbon on the surface of FeO and reducing the reaction activity of FeO; introducing vapour from the bottom of the moving-bed reactor to reduce the deposited carbon on FeO surface, enabling FeO to enter into a bubbling fluidized bed reactor via an L valve, reacting FeO with vapour in the bubbling fluidized bed reactor to generate hydrogen and Fe3O4, enabling Fe34 to enter into a cycle fluidized bed reactor via an external separator; and reacting Fe3O4 with air in the cycle fluidized bed reactor to generate Fe2O3 which is lifted to a cyclone separator for gas-solid separation, enabling Fe2O3 to enter into the moving-bed reactor via the blanking tube of the cyclone separator, so as to realize cyclic utilization of Fe2O3.

Description

technical field [0001] The invention relates to a method and device for hydrogen production from bio-oil, in particular to chain-type hydrogen production from bio-oil based on iron-based oxygen carrier and separation of CO 2 method and device. Background technique [0002] Hydrogen can be directly burned for power generation, heating or used as a fuel for high-performance fuel cells, and is a recognized future clean energy carrier. Hydrogen only produces water and heat during the energy conversion process. It is a non-polluting secondary energy source that truly achieves zero emissions of pollutants. However, hydrogen is a secondary energy source that needs to be obtained through conversion of fossil fuels. Although the traditional fossil fuel hydrogen production process technology is mature, the process is complex and requires a lot of energy consumption, and at the same time emits a large amount of CO into the atmosphere. 2 . CO 2 As a "greenhouse gas", large amounts o...
