Embodiment 1

[0042] (1) Weigh 0.867 grams of Fe(NO 3 )3 9H 2 O, 1.092 grams of 50wt% Mn(NO 3 ) 2 Aqueous solution, add 100ml deionized water to make a solution. Then magnetically stir at constant temperature at 60°C for 20-30min until the solute is completely dissolved to prepare the impregnating solution of the active component.

[0043] (2) Weigh 2 grams of γ-alumina balls with a particle size of about 3.0 mm, wash them with deionized water for 3 times, and then immerse them in the active component impregnation solution, and then transfer all the impregnation solutions and carriers to the Erlenmeyer flask In this process, the water in the solution was completely evaporated to dryness at 80°C, then dried at 110°C for 10 hours, and then calcined at 600°C for 6 hours to obtain Fe with a metal element loading of 12%. 0.5 -Mn 0.5 / γ-Al 2 o 3 catalyst.

Embodiment 2

[0045] (1) Weigh 0.289 grams of Fe(NO 3 ) 3 9H 2 O, 1.820 grams of 50wt% Mn (NO 3 ) 2 Aqueous solution, add 100ml deionized water to make a solution. Then magnetically stir at constant temperature at 60°C for 20-30min until the solute is completely dissolved to prepare the impregnating solution of the active component.

[0046] (2) Weigh 2 grams of γ-alumina balls with a particle size of about 3.0 mm, wash them with deionized water for 3 times, and then immerse them in the active component impregnation solution, and then transfer all the impregnation solutions and carriers to the Erlenmeyer flask In this process, the water in the solution was completely evaporated to dryness at 80°C, then dried at 110°C for 10 hours, and then calcined at 600°C for 6 hours to obtain Fe with a metal element loading of 12%. 0.17 -Mn 0.83 / γ-Al 2 o 3 catalyst.

Embodiment 3

[0048] (1) Weigh 0.594 grams of Ni (NO 3 ) 2 ·6H 2 O, 1.092 grams of 50wt% Mn(NO 3 ) 2 Aqueous solution, add 100ml deionized water to make a solution. Then magnetically stir at constant temperature at 60°C for 20-30min until the solute is completely dissolved to prepare the impregnating solution of the active component.

[0049] (2) Weigh 2 grams of γ-alumina balls with a particle size of about 3.0 mm, wash them with deionized water for 3 times, and then immerse them in the active component impregnation solution, and then transfer all the impregnation solutions and carriers to the Erlenmeyer flask In this method, the water in the solution was completely evaporated to dryness at 80°C, then dried at 110°C for 10 hours, and then calcined at 600°C for 6 hours to prepare Ni with a metal element loading of 12%. 0.5 -Mn 0.5 / γ-Al 2 o 3 catalyst.

Abstract

The invention discloses a catalytic ozonation catalyst for volatile organic waste gas treatment as well as a preparation method and application of the catalytic ozonation catalyst. The catalytic ozonation catalyst comprises a carrier and an active component, wherein the carrier is aluminium oxide, silicon oxide, zeolite or a ceramic ball; the active component comprises manganese oxide and an assistant; and the assistant is an oxide of at least one element of iron, nickel, cobalt, chrome and vanadium. By means of the catalyst disclosed by the invention, the problems that the pollutant removing efficiency is low, the investment cost and the operating cost are high, the reaction condition is strict and the like in existing techniques for treating volatile organic waste gases are solved.

Description

technical field [0001] The invention relates to the technical field of air pollution control, in particular to a catalytic ozone oxidation catalyst for treating volatile organic waste gas, a preparation method and application thereof, and an application thereof in catalytic ozone oxidation of volatile organic waste gas. Background technique [0002] Volatile organic waste gas is an important contribution to the formation of my country's current atmospheric haze pollution and photochemical smog pollution. At present, a series of work has been carried out on how to deepen the protection of the atmospheric environment and reduce the emission of volatile organic waste gases. The common methods for treating volatile organic waste gas at home and abroad include adsorption method, absorption method, plasma method, incineration method and catalytic oxidation method. [0003] For example, the Chinese invention patent application document with the publication number CN103285813A disc...
