Thermocatalytic water decomposition reactor and thermocatalytic water decomposition hydrogen production system and method

Abstract

The invention relates to the technical field of hydrogen production, and discloses a thermocatalytic water decomposition reactor and a thermocatalytic water decomposition hydrogen production system and method. The reactor comprises a reaction tube, a temperature adjusting device and a pressure monitoring device. One end of the reaction tube is an air inlet end, the other end of the reaction tube is an air outlet end, and the air inlet end and the air outlet end are both sealed. The pressure monitoring device is arranged at the air inlet end. The temperature adjusting device is arranged on the periphery of the reaction tube. A catalyst layer is arranged in the reaction tube, a plasmon thermal catalyst is loaded in the catalyst layer, and a diffusion layer and an airflow buffer layer are arranged on the two sides of the catalyst layer sequentially in the axial direction of the reaction tube. Airflow entering from the air inlet end sequentially flows through the airflow buffer layer and the diffusion layer on one side, the catalyst layer, and the diffusion layer and the airflow buffer layer on the other side, and flows out from the air outlet end. Low-temperature waste heat steam is used as a hydrogen production raw material, the reaction temperature is reduced by utilizing the plasmon effect, the hydrogen production energy consumption is greatly reduced, no carbon is emitted in the reaction process, and energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a thermal catalytic water splitting reactor, a thermal catalytic water splitting hydrogen production system and a method. Background technique [0002] Hydrogen energy can flexibly couple multiple energy sources such as electric energy, thermal energy, and fuel, and has multiple advantages such as wide sources, high calorific value, storability, and renewable energy. It is known as the "ultimate energy" in the future. In the context of global carbon neutrality, hydrogen energy will play an important role. [0003] At present, the main methods of hydrogen production include hydrogen production from fossil fuels such as coal and natural gas, hydrogen production from electrolysis of water, and hydrogen production from biomass gasification. Among them, fossil fuels such as coal, oil, and natural gas are the main raw materials for hydrogen production at home and abroad. ...
