SCST-221 High Temperature CO Shift Catalyst

Model：SCST-221

High temperature CO shift catalyst SCST-221 is suitable for the system of ammonia, methanol, hydrogen plant of CO shift reaction, which use different raw materials such as natural gas, coke oven gas, oil field gas, naphtha and so on. The CO reacts with water vapor to produce H₂ and CO₂. The CO content in the out gas is lower than 3%.

The main reaction is as follows:

CO + H₂O_（g）→CO₂ + H₂ + 41.19 KJ/mol

【Industrial Applications】

• The catalyst is suitable for the system of ammonia, methanol, hydrogen plant using natural gas and coke oven gas;
• The catalyst is suitable for the hydrogen plant using catalytic dry gas and coking dry gas;
• The catalyst is suitable for methanol synthesis and ammonia plant using oil field gas, refinery gas and naphtha;
• The catalyst is suitable for CO in coal synthesis gas purification device.

【Physical and Chemical Properties】

【Operation Conditions】

• Operation space velocity: 500 ~ 5000h^-1
• Operation temperature: 300 ~ 500℃
• Operation pressure: ≤ 5.0MPa

【Product Advantages】

• Suitable for low ratio of steam/carbon to achieve energy saving;
• Strong resistant to water vapor condensation: no effect on the catalyst in case of meeting  liquid water in short time;
• Using new catalyst production technology, no need to release sulfur singly,  It is accomplished when the catalyst reduction is over;
• Higher strength and stronger heat resistance than others, especially after catalytic reduction.
