Preparation method of nickel based catalytic air purifying agent

Abstract

The invention discloses a preparation method of a nickel based catalytic air purifying agent. The nickel based catalytic air purifying agent is prepared from the following raw materials including potassium permanganate, manganese acetate, tetrabutyl titanate, montmorillonite powder, rice husks, sodium metaaluminate and nickel nitrate. In the preparation method provided by the invention, through modification by adopting the montmorillonite powder, relatively strong physical absorption performance and stable space structure can be acquired, hazardous substances in air can be more effectively adsorbed; meanwhile, through adsorption with a strong oxidation impregnating solution, excellent oxidation sterilization function is obtained; and on the basis, mayenite is prepared through calcium hydroxide and aluminum hydroxide, and by compounding with a nickel based catalyst and utilizing a free oxygen structure, the carbon deposition resistance of the nickel based catalyst is improved, and the catalytic performance is enhanced; and therefore, the obtained air purifying agent has both of excellent catalytic performance of a nickel base and high adsorption performance of montmorillonite, achieves the purpose of removing various pollutants including organic matters, suspended particles and bacteria in air, is rapid in treatment speed without environmental pollution at the same time and meets the demand of people on current air purification.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to a preparation method of a nickel-based catalytic air purifier. Background technique [0002] With the continuous development of my country's chemical industry, automobile industry, etc., its air pollution is becoming more and more serious, and a large amount of organic pollutants are discharged into the atmosphere. The emission of chemical substances also makes the indoor air full of various pollutants such as particulate matter, formaldehyde, volatile organic compounds, and allergens. The deterioration of air quality has seriously affected people's daily life. In order to create a clean and environmentally friendly living, working and living environment, air purification technology has attracted people's attention. For this reason, a large number of air purification products have appeared on the market. [0003] In the prior art, the most commonly used air puri...

Problems solved by technology

[0003] In the prior art, the most commonly used air purifiers, such as covering-type deodorizing products, use the fragrance of aromatic hydrocarbons to cover various peculiar smells in the air, but in fact do not remove harmful substances in the air; the core of adsorption-type air purifiers The material is activated carbon adsorbent, its adsorption capacity is average, and it will pollute the environment after disposal, so the purification effect is limited; Oxidation products generally use oxidants to oxidize organic matter or fungi to purify the air, but the purification effect is single and may cause secondary pollution. Pollution

[0004] Nickel-based catalyst has excellent catalytic cracking performance of organic pollutants such as benzene series. Inserting it into the preparation of air purifier can increase the number of organic catalytic cracking surface active centers in the purifier and increase the rate of carbon-hydrogen bond breaking in pollutants. To achieve the degradation of pollutants, but because single-metal nickel-based catalysts are prone to carbon deposition and deactivation, it is necessary to find a good composite material and carrier to make the catalyst have the ability to resist carbon deposition and hydrogen sulfide, thereby enhancing the performance of the catalyst
