Methanol Hydrogen Generator

The methanol cracking hydrogen production technology of EVE shares is adopted, using the heat energyprovided by the heat transfer oil furnace to vaporize the methanol, which is cracked and reacted with the vaporized demineralized water under the action of the catalyst to generate the shift gas; The shifted gas is then passed through a PSA unit, which utilizes the selective adsorption properties of the adsorbent to remove impurities (mainly CO and CO2) from the shifted gas, separating out hydrogen with a purity greater than 99.99% and sending it to the hydrogenation unit.

 

A catalytic combustion reaction equipment for methanol-to-hydrogen production, mainly consisting of a catalytic combustion unit, a vaporization and superheating unit, a methanol cracking reaction unit, and a circulating fan, as well as a combustion-supporting fan, an air preheater, and other components.

1) The mixture of methanol and water is vaporized and superheated by a vaporization superheater, with heat coming from the circulating flue gas;

2) The overheated mixed gas enters the reactor and generates a mixture of hydrogen, carbon dioxide, trace carbon monoxide, and methane under the action of the catalyst.

3) The combustion air is boosted by the blower and enters the air preheater, where it exchanges heat with some of the outlet flue gas from the circulating fan. The heat-exchanged combustion air enters the catalytic combustion unit to provide fresh air.

4) The fuel is mainly methanol or pressure swing adsorption desorption gas;

5) The temperature of the flue gas circulating into the reactor is controlled by the circulation volume of the circulating fan. The temperature of T is controlled within the range of 350-450℃;
