Methanol-to-Hydrogen Process
This process adopts direct combustion/catalytic combustion technology, eliminating the need for heat transfer oil as a medium. Methanol reacts directly with water under heating conditions to generate an H₂/CO₂ mixture, which is then cooled and separated. Hydrogen is further purified via membrane separation or PSA technology.
Core Reaction Equipment:
1. Catalytic combustion heating unit
2. Vaporization and superheating unit
3. Methanol cracking reaction unit
4. Flue gas circulation fan system
Auxiliary Equipment: Includes combustion-supporting fan, air preheater, and other components, forming a complete reaction system.
Process Flow Control Key Points:
1. Methanol-water solution is vaporized and superheated using flue gas waste heat.
2. The superheated mixture undergoes catalytic cracking to produce hydrogen.
3. Preheated combustion air enters the combustion unit.
4. Fuel sources include methanol or PSA desorption gas.
5. Circulating flue gas temperature is controlled at 350–450 °C.
