Description

Technical Field

[0001] The invention relates to the technical field of hydrogen production devices, and in particular to a novel methanol hydrogen production reactor. Background Art

[0002] With the popularization and development of new energy technologies, the development of hydrogen fuel cells is becoming more and more perfect, and the related methanol hydrogen production technology is also becoming more mature. In the process of methanol hydrogen production, high-temperature reforming of methanol is the most critical step in the entire hydrogen production process. This step requires a stable high-temperature environment to allow methanol to stably react with the catalyst to generate hydrogen-rich gas. In the prior art, in order to reduce energy consumption and reduce costs in chemical production, a methanol hydrogen production device is used to replace the "electrolysis of water to produce hydrogen" process known as the "electric tiger". It uses advanced methanol vapor reforming and pressure swing adsorption technology to produce pure hydrogen and a mixed gas rich in CO2. After methanol and water vapor pass through a catalyst under certain temperature and pressure conditions, under the action of the catalyst, a methanol cracking reaction and a carbon monoxide shift reaction occur to generate hydrogen and carbon dioxide, which can reduce the cost of manufacturing hydrogen. When the existing methanol hydrogen production device is in use, when heating the mixed raw material of methanol and desalted water, the heating speed is slow and the heating effect is insufficient, which will reduce the efficiency of hydrogen production. Therefore, a new methanol hydrogen production reactor is proposed. Summary of the invention
