After pre-treatment, natural gas or other light hydrocarbon raw materials are mixed with steam and enter a special conversion furnace. Under the action of nickel catalyst SCST-20X, steam reforming reaction occurs to generate conversion gas containing H₂, CO₂, CO and other components. After recovering heat from the conversion gas, the conversion gas containing CO₂ and H₂ is obtained through water vapor shift reaction, and then purified by PSA to obtain high-purity H₂. The PSA tail gas is returned to the conversion furnace for combustion and heat recovery.

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%.

SCST-CHMR catalytic heating coupled with methanol-to-hydrogen technology is mainly used to produce 99-99.9995% pure industrial hydrogen from methanol and demineralized water. Methanol and water are mixed in a certain proportion, heated and vaporized, and superheated. After reaching a certain temperature and pressure, a catalyst is used to generate reformed gas containing mainly H2, CO2, and small amounts of CO, CH3OH, and CH4. This reformed gas then enters a PSA system for purification to obtain 99-99.9995% (V) pure industrial hydrogen. The PSA desorbed gas (tail gas) passes through a catalytic heating system to heat the methanol reforming system, eliminating the need for an external heat source. Application scenarios include:
