How Steam Methane Reforming Works
NG Reacts with Steam at 1500° to 1600° Fahrenheit and a nickel catalyst to strip out the H2.
Result is unpure mixture of H2, CO, CO2, steam and unreacted Methane.
Mixture is cooled to 750°.
More steam is added, creating more H2, and converting the CO to CO2.
Remaining impurities are then extracted.
