Via making pump mixing the methanol and water at a specific ratio, and the mixture pump through a heat exchanger to be heated up, then flow through a gasifier, and further heating till temperature of 220℃ — 280 ℃ before flowing through a reactor, under the influence of catalytic after the following reaction take place:
Decomposition reaction: CH3OH→CO + 2H2–90.7 kj/mol1
Decomposition reaction: CO + H2O→CO2 + H2+ 41.2 kj/mol2
Final result: CH3OH + H2O→CO2 + 3H2–49.5 kj/mol
The hot gases produced after the reactor first flow through the heat exchanger to heat up themethanol/water mixture, then cool down through a cooler. The final product is 74%H2,24.5% CO2,0.5% CO, very minimum content of CH4, higher purity H2 can be improved through PSA system.
