Hydrogen Production Technology
Conventional Methanol-to-Hydrogen Technology
1. Methanol-to-hydrogen technology has certain advantages among various hydrogen production technologies due to its wide availability of raw materials, technological maturity, ease of operation, economic efficiency, and environmental friendliness.
2. Process Flow: Methanol and steam, under specific pressure and temperature conditions, pass through a methanol-steam reforming catalyst bed to generate reformed gas, whose main products are carbon dioxide and hydrogen. This reformed gas is then subjected to pressure swing adsorption to obtain product hydrogen with a purity of 99.0%~99.999%.
Chemical Reaction:
CH₃OH → CO + 2H₂ ΔH = +90.7 KJ/mol
CO + H₂O → H₂ + CO₂ ΔH = -41.2 KJ/mol
Overall Reaction: CH₃OH + H₂O → 3H₂ + CO₂ ΔH = +49.5 KJ/mol
