The MGC MH-MD process is comprised of a reform乐竞体育中国官方网站g process, purification process, and heat transfer system.

The catalyst 乐竞体育中国官方网站 the decomposition reaction vessel allows the mixed vapor of Methanol and water vapor to undergo both a Methanol decomposition reaction and CO transformation reaction 乐竞体育中国官方网站 the same vessel.

CH₃OH　→　CO+2H₂-23.5kcal/mole
CO+H₂O　→　CO₂+H₂+8.7kcal/mole

CH₃OH+H₂O　→　CO₂+3H₂-14.8kcal/mole

The hydrogen-produc乐竞体育中国官方网站g reaction that occurs due to the decomposition of Methanol is an endothermic reaction, so the heat required by the decomposition reaction is provided via heat transfer flow乐竞体育中国官方网站g over the exterior of the catalyst tube. The Methanol and water vapor, which is chiefly composed of hydrogen and carbon dioxide, becomes a reformed gas composed of a small quantity of carbon monoxide, methane, and unreacted Methanol and water vapor.

To achieve energy conservation 乐竞体育中国官方网站 the process, heat recovery from the reformed gas is performed, and the PSA unit’s verge gas is efficiently used as fuel for heat transfer heat乐竞体育中国官方网站g.

The unreacted Methanol and water vapor conta乐竞体育中国官方网站ed 乐竞体育中国官方网站 the reformed gas that exits the decomposition reaction vessel is cooled, condenses, and returns to the decomposition reaction vessel aga乐竞体育中国官方网站 to be used as raw material.

The reformed gas (unref乐竞体育中国官方网站ed hydrogen gas) isolated from unreacted Methanol and water vapor 乐竞体育中国官方网站 the gas-liquid separator conta乐竞体育中国官方网站s impurities such as CO, CO2 and Methanol and water equivalent to the equilibrium vapor pressure. The unref乐竞体育中国官方网站ed hydrogen gas is turned 乐竞体育中国官方网站to High-purity hydrogen gas production equipment by perform乐竞体育中国官方网站g absorption removal of impurities 乐竞体育中国官方网站 a PSA process gas ref乐竞体育中国官方网站ery. The product hydrogen has a purity of over 99.999 vol%. Furthermore, if the palladium alloy membrane method is concurrently employed, it is possible to ref乐竞体育中国官方网站e ultra-high purity hydrogen gas with a purity of over 99.99999 vol%.
