Description

Technical field [0001] The present invention relates to the field of hydrogen production apparatus, and more particularly to a self-heating methanol reforming hydrogen reactor. Background technique [0002] With the increasing growth of global energy demand, the dependence on fossil fuels and the resulting environment, climate problems are also increasingly serious. Develop cleaner, efficient new energy technology is an effective way to solve environmental pollution and ensure energy supply. The fuel cell is a device that directly converts hydrogen and oxygen directly into electrical energy, and the process does not involve combustion, not subject to the cycle limit, high energy conversion efficiency, product is electricity, heat and water, no pollution It is considered to be one of the new energy technologies in the 21st century. Among them, the proton exchange membrane fuel cell has been first applied in the field of mobile power, fixed alternate power generation and automobile...

AI Technical Summary

Problems solved by technology

Tubular reactors are more convenient to process, but there are often uneven heating phenomena, especially prone to "hot spots", resulting in catalyst sintering failure in the tube

Microchannel reactors have a large surface area, but the processing is more complicated and the cost is higher, which is not conducive to scale-up

In addition, some methanol reforming hydrogen production reactors rely on external power supply racks for heating. Although the structural design is more simplified, it is greatly compromised in terms of hydrogen production economy and ease of use.
