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 coupled with biomass supercritical water gasification and multi-disk focused heat supply. Background technique [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 directly process bioma...
