High-Temperature Methanol to Hydrogen Catalyst SCST-403 High Conversion Rate, Few Side Reactions, High Strength
- Application
SCST-403 high-temperature methanol to hydrogen catalyst is mainly used for the reforming and shift reaction of methanol and water under high temperature conditions of 300°C and above. Methanol and steam react through the catalyst bed to generate H2, CO2, a small amount of CO and CH4, to produce the required hydrogen. This catalyst is the latest research achievement of Sichuan Shutai Chemical Technology Co., Ltd., mainly suitable for the methanol to hydrogen process in methanol fuel cell systems, methanol combustion boilers and methanol to hydrogen systems.
The main reactions are as follows:
CH3OH+H2O=CO2+3H2 +49.5 kJ/mol
CH3OH=CO+2H2 +90.7 kJ/mol
CO+H2O=CO2+H2 +41.19 kJ/mol
CO+3H2=CH4+H2O -206.3 kJ/mol
2CH3OH =CH3OCH3+H2O -24.9 kJ/mol
