Problems solved by technology

[0007] However, the conventional reactor system usually connects multiple reactors in series in steps (for example, it needs to be realized by manual welding, etc.), and usually needs to use more than one heat sink to dissipate heat from the entire reactor system. Too complicated and expensive
Moreover, even if the cascaded design is adopted, the whole reactor system is still prone to local overheating when the reaction gas flow rate changes greatly. Although the conventional reactor system can often make the conversion rate of reaction A reach 100%, the excessive A high temperature will lead to a decrease in catalyst activity and intensify reaction B (making reaction B have a conversion rate of about 5% to about 40%), which will cause a large amount of hydrogen to be consumed and significantly reduce the efficiency of hydrogen production

Description

technical field [0001] The present invention relates to a temperature-controlled monomer reactor, and more particularly, to a temperature-controlled monomer reactor for use in a fuel cell system (for example, a low-temperature proton exchange membrane fuel cell system). 1. The carbon monoxide preferential methanation reaction of the reaction gas obtained by the fuel reforming reaction. Background technique [0002] It is known in the field of fuel cell systems that there are various fuel types for producing hydrogen, such as alkanes (methane, ethane, etc.), alcohols (methanol, ethanol, etc.), gasoline, diesel, etc. These fuels usually produce hydrogen through fuel reforming reactions (mainly including three reforming methods: fuel vaporization reforming reaction, fuel autothermal reforming reaction and fuel partial oxidation reforming reaction, among which fuel vaporization reforming reaction is the most commonly used) to produce hydrogen, for example , the reaction formula...
