Carbon Monoxide Low-Temperature Shift Catalyst SCST-231 High Strength, Good Active Components, High Conversion Rate
Price: 380-450/kg
- Application
SCST-231 CO low-temperature shift catalyst is used to convert carbon monoxide in synthesis gas such as natural gas, refinery gas, coke oven gas and blast furnace gas into carbon dioxide. After medium (high) temperature shift, it enters the low-temperature shift furnace to make the carbon monoxide (dry gas) in the low-temperature shift furnace gas less than 0.3%, thereby achieving the purpose of gas purification. The main reaction is as follows:
CO+H2O= CO2+H2 -41.19 kJ/mol

- Application Fields
Natural gas to synthesis ammonia, hydrogen production units;
Coke oven gas to synthesis ammonia, hydrogen production units;
Catalytic dry gas, coking dry gas to synthesis ammonia, hydrogen production units;
Oilfield gas, refinery gas, naphtha, etc. as feedstock for synthesis ammonia, hydrogen production units;
CO purification units in coal-to-synthesis gas.
- Catalyst Characteristics
Low loss on ignition, small shrinkage rate, the catalyst basically does not sink after reduction;
Good dispersion of active components, high conversion rate, the conversion rate can reach more than 95% under normal process conditions;
For some high-sulfur gas units, better anti-poisoning performance, will not lead to poisoning and deactivation in a short time;
New promoters added, fewer by-products, thereby achieving the purpose of energy saving and consumption reduction.
- 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.
