Innovative Methanol-to-Hydrogen Process
This process innovates beyond traditional methods by adopting 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/CO₂mixture, which is then cooled and separated. Hydrogen is further purified via membrane separation or PSA technology, resulting in a simple and efficient process flow.
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 precisely controlled at 350–450 °C.
