Methanol decomposition

Methanol decomposition

CH3OH —→ CO + 2H2

△H0298= +90.6kJ/mol

After methanol is preheated and vaporized, superheated to the reaction temperature, it passes through the catalyst bed and then catalyzes the reaction to generate a mixture of hydrogen and carbon monoxide.After the mixed gas is separated, the product hydrogen and carbon monoxide are obtained.Among them, carbon monoxide can be applied in many fields.Therefore, the hydrogen production process of methanol decomposition has great economic advantages, and two kinds of gas products can be obtained, thereby greatly improving the advanced nature of the process.Methanol cracking reaction can occur under normal pressure, and the general reaction temperature is 200-500°C.Low-temperature catalysts with high activity, high selectivity, and high stability play an important role in the hydrogen production process of methanol cracking. Commonly used methanol cracking catalysts include Cu-based catalysts and noble metal-supported catalysts.Among them, the Cu-based catalyst has the same performance as the methanol steam reforming hydrogen production catalyst.Therefore, the methanol steam reforming hydrogen production catalyst can be directly applied to the methanol decomposition hydrogen production process.
