Carbon Monoxide (CO) Removal Catalyst (Fireplace & Oven Special Type)
Carbon Monoxide (CO) Removal Catalysts is specifically targeted at the exhaust treatment of fireplaces and ovens, and has a good catalytic purification effect. Fireplaces and ovens are susceptible to harmful emissions of carbon monoxide CO and incompletely combusted hydrocarbons CnHm during the combustion process. Under the action of the catalyst, the exhaust gas of the oven undergoes catalytic oxidation, and the CO and CnHm in the exhaust gas generate carbon dioxide, CO2 and water H2O, which can be emitted.
Under the conditions of temperature of 250 ~ 400 ℃ and space velocity (0.3 ～ 1) × 104h−1, the content of carbon monoxide and non-methane hydrocarbons can be reduced below 4mg / m3. The catalyst can be reused repeatedly, has good mechanical strength, and has a service life of more than 2 years.
The catalyst needs to be preheated to 200 ~ 250 ℃ for activation before use, and then the tail gas should be treated. The operating temperature is preferably above 300 ℃. Under the reaction conditions of 1.5 ~ 3.0 × 103h-1, the CO in the tail gas can be eliminated to below 0.5 ppm, and the total non-methane hydrocarbons can be reduced to below 1 ppm. The maximum heat-resistant temperature is 750 ° C (if the concentration of flammable gas is high, a cooling system is required to prevent catalyst sintering).
