Among the biomass conversion and various industrial by-products, carbon monoxide is a relatively readily available gas. The hydrogen is produced by the shift reaction of carbon monoxide and water vapor, which is a feasible transformation scheme and has wide market prospect. Due to the characteristics of the biomass, the hydrogen production technology using the biomass as the raw material has great advantages, and belongs to zero carbon emission or negative carbon emission from the life cycle. The hydrogen production by using biomass is usually carried out by converting biomass raw material into biomass fuel gas and biomass charcoal, reforming the fuel gas and reacting the biomass fuel gas with water gas of the charcoal to prepare mixed gas of hydrogen and carbon monoxide, and separating to obtain the hydrogen.

Moreover, the shift reaction is a strong exothermic reaction, and the temperature runaway phenomenon is easy to occur if the shift reaction is not controlled properly, so that the reaction effect is reduced, and the service life of the catalyst is influenced.
