Abstract

The invention provides an amine odor removal material, and belongs to the field of odor removal materials. The preparation method comprises the following steps: (1) carrying out hydro-thermal treatment on an adsorption material in a reactor by using an inorganic salt solution, and performing cleaning and drying to obtain a modified material carrier; (2) impregnating the modified material carrier in an acidic solution, and drying the modified material carrier to obtain an impregnated carrier; and (3) preparing a catalytic active precursor solution, impregnating the impregnated carrier into thecatalytic active precursor solution again in an isopyknic manner, carrying out heat preservation reaction, and then performing roasting to obtain the material. According to the invention, the specificsurface area, porosity and average pore size of the selected adsorption material can be effectively adjusted, the graded loading capacity can be realized, the material loading effect is more excellent, and various amine malodorous gases can be effectively removed at the same time through the synergistic effect of catalysis and adsorption in a normal-temperature environment.

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 awareness of the environment has gradually increased. As one of the environmental hazards, odor pollution has attracted great attention worldwide. Odor pollution mainly includes two types of odors generated in daily life and odors generated in industrial production. The sources of stench in daily life include: the stench emitted by interior decoration materials, including paints, adhesives and other stench gases containing volatile organic compounds that are more poisonous to the human body; Pet rooms are places where bad odors often occur. Odor sources in industrial production mainly include: chemical plants, pesticide plants, paint plants, food fermentation plants, poultry plants, etc. These malodorous gases mainly include vol...
