Industrial waste gas dioxin removal catalyst desulfurizer

Industrial waste gas dioxin removal catalystAs a new product in the dioxin removal market, it has the characteristics of high removal efficiency, wide applicable temperature range, and multiple catalyst types. Based on the characteristics of the catalyst, the installation and layout can be carried out using a high-temperature and high dust method to maintain the catalyst's excellent reaction activity. The dioxin removal system can be low-cost, and a collaborative NOx and dioxin removal system can also be selected as needed.

Steel smelting, non-ferrous metal smelting, automobile exhaust, incineration production (including pharmaceutical wastewater incineration, waste incineration in chemical plants, household waste incineration, coal-fired power plants, etc.). Lead containing gasoline, coal, wood that has undergone anti-corrosion treatment, petroleum products, and various types of waste, especially medical waste, are prone to produce dioxins when burned at temperatures below 300-400 ℃. The production processes of polyvinyl chloride plastics, paper, and certain drugs, steel smelting, and high-temperature activation of catalysts can all release dioxins into the environment. Dioxins also exist as impurities in some pharmaceutical products such as 2,4,5-T. Dioxins in flue gas can be treated with modified SCR catalysts. Zhongneng Guoxin has independently developed dioxin removal catalysts, which have been applied in multiple chemical plants, waste incineration, and hazardous waste incineration plants with high removal rates.

Ensure the efficiency of the original SCR catalyst

Catalyst modification:

Dioxin removal: Introducing transition metals such as Ni and Cu, as well as rare earth metals such as Ce and La, to modify existing composite oxide SCR catalysts, in order to balance the SCR denitrification performance and the SCO decomposition performance of dioxins.

Mercury co catalyst: Introducing active metals such as manganese to modify existing oxide SCR catalysts and balance denitrification and mercury removal performance.

Efficiency of system denitrification oxidation:

Mercury removal efficiency:>95%

Dioxin removal efficiency:>90%
