Secondary Reforming Catalyst SCST-213 High Strength, High Conversion Rate, Long Service Life
- Application
SCST-213 secondary reforming catalyst is mainly used in the secondary reforming section of synthesis hydrogen and hydrogen production units from natural gas, coke oven gas and other synthesis gases. It is also used in the pure oxygen or oxygen-enriched reforming section of methanol, synthesis ammonia and hydrogen production units with coke oven gas as feedstock. The main reactions are as follows:
CH4+H2O=CO+3H2 -206.3 kJ/mol
CH4 + 2H2O=CO2+4H2 -165.3kJ/mol
CO+H2O=CO2+H2 +41.19kJ/mol
2H2+O2=2H2O +241.8 kJ/mol

Long service life, under long-term high-temperature atmosphere, the service life exceeds five years under normal operating conditions.
- Packaging, Storage and Transportation
The finished catalyst is packed in plastic drums or iron drums lined with plastic bags. During transportation and storage, it must be protected from moisture, fire, inverted placement and strictly prohibited from chemical contamination. Rolling or impact is strictly prohibited during handling; when stored outdoors, place sleepers at the bottom and cover with canvas for rain protection; it can also be packed in ton bags according to user requirements.
