Abstract

The invention discloses an oxidizing and gasifying hydrogen-making device and method of hypercritical water fluid-bed part of the biological waste, which is characterized by the following: adopting hypercritical water fluid-bed reactor to prevent slagging and blocking problem in the pipe flow reactor; using high-pressure separator to generate high-pressure water to adsorb carbon dioxide in the gas product; realizing the separation of the hydrogen from the carbon dioxide; making the separated high-density carbon dioxide concentrate to be disposed and do resoursing usage conveniently; compacting the device structure; simplifying and conveniencing the operation; improving the gasifying rate of the biological waste with less pollution in the liquid product; realizing the oxidizing and gasifying fusion in the reactor; improving the biological mass transmitting rate and system energy transmitting efficiency; transmitting the biological waste into high-quality hydrogen through the method; reducing the environmental pollution; realizing the dual goals to harness pollution and make hydrogen.

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 ...
