AI Technical Summary
Technical Problem
During cold start-up of existing methanol-to-hydrogen systems, traditional preheating methods are energy-intensive, slow, and have uneven temperature distribution, posing risks of heat source scarcity and localized overheating.
Method used
A rapid preheating device based on mixed gas combustion is adopted, which uses the mixed gas generated during hydrogen production as fuel. Through the cooperation of combustion preheating module and mixed gas delivery module, combined with an automatically adjustable oxygen supply unit, the catalyst bed is rapidly and uniformly preheated.
Benefits of technology
It improves preheating efficiency, shortens cold start time, ensures uniformity and stability of preheating, reduces energy consumption, and avoids local overheating.
