Device and method for preparing and co-producing hydrogen from biomass chemical chain carbonization catalytic material

Abstract

The invention relates to the technical field of functional materials, energy conversion and environmental protection, in particular to a device and a method for preparing co-production hydrogen from a biomass chemical chain carbonization catalytic material. An air distribution plate is arranged in the reactor and divides an inner cavity of the reactor into a biomass chemical looping carbonization reactor at the upper part and a catalyst regeneration combustion chamber at the lower part; the biomass chemical looping carbonization reactor utilizes lattice oxygen of MOx to realize biomass carbonization, MOx is reduced at the same time, and M particles are generated and uniformly supported on the surface of the biochar to form an M / C catalyst; high-temperature gas carrying heat generated by combustion of the catalyst regeneration combustion chamber upwards enters the biomass chemical looping carbonization reactor through an air distribution plate, and heat energy is provided for biomass carbonization reaction; the catalyst regeneration combustion chamber is also used for activating the spent M / C catalyst into MOx. According to the method, CO2 gas trapping is achieved, and gradient utilization of energy is achieved; the problem that a methanol steam reforming hydrogen production catalyst is easy to inactivate is effectively solved.
