Abstract

The invention discloses a catalyst for removing nitrogen oxide and organic pollutant discharged in burning, comprising carbon nanotube and alumina as the carrier and manganese oxide as the active ingredient, the active ingredient in the catalyst accounts for 1 to 10% of the total catalyst mass. The catalyst is prepared by a solvent-thermal method. In the inventive catalyst, CNTs and Al2O3 are simultaneously used as the carrier for the first time, thus the catalyst has big specific surface area and high mechanical strength, at the same tine the temperature of the selective catalytic reaction is reduced, 94.2% of chlorobenzene removing ratio can be obtained at the temperature of 150 DEG C, 88.8% of NOx removing ratio is obtained at the temperature of 200 DEG C. The catalyst can be used for removing the nitrogen oxide (NOx)and dioxin organic pollutant discharged in the high-temperature process in the fire coal power plant, metallurgy industry, garbage burning and the like.

Description

technical field

[0001] The invention relates to a method for removing nitrogen oxides (NOx) emitted from high-temperature processes such as coal-fired power plants, metallurgical industries, and garbage incineration. X ) and dioxin (Dioxin) type persistent organic pollutants catalyst and preparation method. Background technique

[0002] With the improvement of my country's comprehensive national strength, people's living standards have been continuously improved at the same time, accompanied by a large amount of energy consumption and the deterioration of the environment. Among them, nitrogen oxides (NO X ) and dioxin (Dioxin) persistent organic pollutants are two main factors of environmental pollution. For example, in 2000 China's NO emissions into the atmosphere X The total amount reached 15 million tons, far exceeding the amount of NO produced by natural processes such as lightning. X amount (estimated at 380,000 tons per year in China). The emission of PCDD / DFs in ...
