The buffering cavity, the distribution cavity, the mixing cavity and the distribution cavity of raw materials are designed, so that theproblem that the materials in a small-size reaction space are uniformly distributed is solved. A valve group is designed so that the energy efficiency of the hydrogen production reactor is improved.To sum up, the hydrogen production reactor provided by the invention has the appearance characteristics of compactness and small size, has the advantages of high combustion efficiency and heat transferring efficiency, and capability of reducing heat transferring resistance in a heat absorption process and a heat release process, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of hydrogen energy, and specifically relates to a hydrogen production reactor coupled with heat absorption and heat absorption, which converts hydrogen-containing raw materials (alcohols, alkanes, etc.) into hydrogen-rich gas through the matching of strong heat release and strong heat absorption. Background technique [0002] With the development of society, many problems such as energy shortage, environmental pollution and greenhouse effect have become the focus of attention of governments all over the world. In order to protect the environment on which human beings live and sustain economic development, the development of clean new energy and renewable energy is becoming a common choice for economic development of all countries in the world. As a zero-carbon or low-carbon energy, hydrogen energy can be stored and conveniently transported. The "hydrogen economy" centered on it may bring about major changes ...

AI Technical Summary

Problems solved by technology

For this kind of reactor where endothermic reaction and exothermic reaction are carried out simultaneously, when the amount and speed of endothermic and exothermic reactions are inconsistent, it will be directly manifested by the change of reaction temperature. The area of ​​endothermic reaction is characterized by high reaction temperature, which is more likely to cause severe local overheating, which will lead to early deactivation of the catalyst, increased side reactions, and unqualified product gas; while the heat release rate is too slow, it will lead to endothermic The reaction temperature of the reaction is too low, which directly leads to a decrease in the conversion rate of the reaction, or even fails to proceed normally.
