Problems solved by technology

At present, methanol reforming hydrogen production equipment mostly uses a tubular reactor filled with catalyst particles to produce hydrogen, and uses electric heating to supply heat to the tubular reactor, which is large and heavy, while the tubular reactor is methanol The main reason for the large volume and weight of reforming hydrogen production equipment is that the tubular reactor also has the problem of being unable to change the device according to different hydrogen production requirements

Methanol reforming hydrogen production equipment still uses granular catalysts as catalyst carriers, resulting in large gas flow pressure resistance during methanol reforming hydrogen production, and granular catalysts are not easy to fill; Reactor heating, it is difficult to ensure uniform heating of the reaction gas in the reactor
