SCST-231 Low Temperature CO Shift Catalyst

Model：SCST-231

Low temperature CO shift catalyst SCST-231 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 CO_2.

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.(Requires the total sulfur content is less than 0.5ppm.)

【Physical and Chemical Properties】

【Operation Conditions】

• S content in feed gas: ≤0.5 ppm
• Cl^- content in feed gas: ≤0.03 ppm
• Steam/feed gas: 0.3~0.6
• Operation temperature: 170~260℃
• Operation pressure: ≤5.0MPa
• Operation space velocity: ≤3000 h^-1（dry gas）

【Product Advantages】

• Smaller shrinkage: does not decrease after the reduction;
• Better active components dispersing and higher conversion rate: the conversion can reach above 93% under normal process conditions;
• Better anti-poison performance for some high-sulfur condition,can’t be poisoned or lose activity in a short time;
• By adding of new auxiliaries, by-products will be less,thus saving utilities and production cost.
