Description

Technical Field

[0001] The utility model belongs to the technical field of methanol hydrogen generators, and particularly relates to a methanol hydrogen generator into which a catalyst can be added intermittently and quantitatively. Background Art

[0002] A methanol hydrogen generator is a device that converts methanol (CH3OH) and water (H2O) into hydrogen (H2) and carbon dioxide (CO2) through a catalytic reforming reaction. This device is very useful in fuel cells, distributed energy systems, and other applications requiring hydrogen. Catalysts play a crucial role in methanol hydrogen generators. They significantly reduce the activation energy of chemical reactions, thereby accelerating the reaction rate, while maintaining their chemical properties. During hydrogen production, controlled catalyst addition is crucial. Catalyst dosage significantly impacts reaction efficiency, selectivity, and overall system performance. Insufficient catalyst dosage reduces the reaction rate, resulting in a decrease in conversion and reduced hydrogen production. Excessive catalyst addition not only increases costs but can also increase reactor pressure, affect reaction uniformity, and even induce side reactions. Furthermore, catalysts are generally expensive. Therefore, it is necessary to minimize catalyst dosage while maintaining reaction efficiency to reduce costs. Therefore, a well-designed control structure for intermittent, quantitative catalyst addition is essential in methanol hydrogen generators.

[0003] In summary, a methanol hydrogen generator without intermittent quantitative addition of catalyst has some problems in use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
