Description

technical field [0001] The invention belongs to the field of energy-based clean utilization of renewable resources and waste, and in particular relates to a hydrogen production device and method for supercritical water fluidized bed partial oxidation gasification of biomass waste. technical background [0002] With the gradual consumption and depletion of fossil energy, it is imminent to find new alternative energy. Biomass, as an abundant resource on the earth, contributes to environmental CO2 during its utilization. 2 The net emission is "zero", therefore, the conversion and utilization of biomass has attracted widespread attention. [0003] Thermochemical gasification is considered to be the most commercially promising biomass utilization technology. However, the traditional biomass thermochemical gasification technology needs to dry the biomass, which consumes a lot of energy. Supercritical water gasification hydrogen production technology can ...

Problems solved by technology

[0006] (1) When the reaction is incomplete, or the flow, transfer, and reaction conditions are not coupled, and the design is unreasonable, the tube flow reactor used in the biomass supercritical water gasification process is prone to wall slagging and clogging, resulting in biomass waste failure of continuous gasification;

[0007] (2) The gasification reaction needs to absorb a large amount of heat, and it is difficult to achieve the rapid temperature rise conditions required for complete biomass gasification by using external heating methods, and at the same time, the energy conversion efficiency of the entire system is low;
