SCST-241 Methanation Catalyst

Model：SCST-241

Methanation catalyst SCST-241 is mainly suitable for synthesis ammonia or hydrogen producing plant to convert the low concentration of carbon monoxide and carbon dioxide in the hydrogen-enriched feed gas to methane and water. The purpose is to purify the gas.

The main reactions are as following:

CO + 3H₂ → CH₄ + H₂O + 206.2 KJ/mol

CO₂ + 4H₂ → CH₄ + 2H₂O + 165 KJ/mol

【Industrial Applications】

• The catalyst is suitable for the system of CO and CO₂ purification plant.
• The catalyst is suitable for CO and CO₂ in catalytic dry gas and coking dry gas purification plant.
• The catalyst is suitable for CO and CO₂ in oil field gas, refinery gas and naphtha purification plant.
• The catalyst is suitable for LNG, CNG plant with coal and coke oven gas.

【Physical and Chemical Properties】

【Operation Conditions】

• S content in feed gas: ≤ 0.1ppm
• Cl^- content in feed gas: ≤ 0.03ppm
• Operation temperature range: 230 ~ 430℃
• Inlet temperature on primary stage: 230 ~ 270℃
• Operation pressure: 0.5 ~ 32.0MPa      
• Operation space velocity: ≤ 13000h^-1

【Product Advantages】

• Shorter reduction time and saving energy;
• Resistance to high pressure, high space velocity: The space velocity can reach 15000h^-1 at 32MPa;
• With the new auxiliaries addition, it has a high conversion and high activity at low temperature;
• No physical water, lower volume shrinkage and lower strength reduction rate after reduction.
