Abstract

The invention provides an amine deodorizing material, which belongs to the field of deodorizing materials. The preparation method includes the following steps: (1) hydrothermally treating the adsorption material in the reactor with an inorganic salt solution, cleaning and drying to obtain a modified material carrier; (2) placing the modified material carrier in an acidic solution After impregnation, drying is performed to obtain an impregnated carrier; (3) a catalytically active precursor solution is configured, and the impregnated carrier is again immersed in the catalytically active precursor solution in equal volume, and the reaction is kept warm, and then calcined to obtain . The invention can effectively adjust the specific surface area, porosity and average pore size of the selected adsorbent material, can match the loading amount in grades, and the material loading effect is more superior, and then effectively removes various amines at the same time through the synergistic effect of catalysis and adsorption in a normal temperature environment odorous gas.

Description

technical field [0001] The invention relates to the field of deodorizing materials, in particular to an amine deodorizing material. Background technique [0002] With the development of the economy and the improvement of living standards, people's environmental awareness has gradually increased, and odor pollution, as one of the environmental hazards, has received high attention worldwide. Odor pollution mainly includes two types of odors produced in daily life and odors produced in industrial production. The sources of odors in daily life include: odors emitted by interior decoration materials, including paints, adhesives and other odorous gases containing volatile organic compounds that are more toxic to humans; in addition, kitchens, living rooms, toilets, garbage dumps, Pet rooms are places where foul odors often occur. The main sources of malodor in industrial production are: chemical plants, pesticide plants, paint plants, food fermentation plants, poultry plants, et...
