High temperature SCR denitration catalyst - iron-based molecular sieve

High vacancy, high activity: diesel engine group, coal-fired power plant and other SCR denitration applications, with a large amount of dust and other impurities, only large holes, low-altitude versus vanadium-based catalysts, and low flue gas design flow rate, reaction The design size is large, resulting in a large amount of flue gas temperature; triple supply of gas unit is very strict control of flue gas temperature loss, requires minimal temperature loss, and iron-based molecular sieve catalysts can reduce the loss of flue gas heat, improve Lithium bromide, lithium bromide, hot water boiler, etc. Work efficiency. Therefore, the high-temperature segment iron-based molecular sieve SCR catalyst is significantly more suitable for the demand for triple to gas unit and gas turbine denitration relative to the vanadium-based SCR catalyst.

Wan pure high temperature catalyst technology maturity: the iron-based molecular sieve catalyst produced by Hebei Danzhong developed from catalyst, high temperature adaptability, anti-aging, and hard-resistant, etc., and has been successfully applied for many years, technology Very advanced.

Energy-based iron-based molecular sieve catalyst performance characteristics

• Ensure the high activity of the catalyst.
? Very low SO2 oxidation rate.
• Very high antivodyability: The catalyst has the ability to absorb a large number of toxicities without causing decrease in activity.
• High tolerance of thermal shock and mechanical impact: catalyst has high tolerance. Can run under any normal load of the device;
• The catalyst can meet the long-term operation of the flue gas temperature is not higher than 550 ° C, and it can withstand the test of 550 ° C for 5 hours in operation temperature without any damage;
• At the same time, at the same time, it is possible to effectively prevent sphenoid, blockage and poisoning phenomenon in catalysts.
• Catalysts that may cause any trace elements contained in the fuel should be considered;
• Before installing new catalysts, the catalyst volume satisfies the requirements of denitrify efficiency and ammonia in performance.
