Abstract

The invention relates to a preparation method of a carbon-based composite material for catalytically degrading volatile organic compounds at room temperature, and a testing device. The method comprises the following steps: with modified activated carbon, clay, a first modified metal oxide 1 and a second modified metal oxide 2 as raw materials, conducting full mixing and granulating or extrusion-molding to prepare a columnar or spherical particle or honeycomb cube; and roasting the columnar or spherical particle or honeycomb cube in an inert atmosphere to obtain the formed carbon-based composite material with high specific surface area, high strength and long service life. The obtained columnar or spherical or honeycomb-shaped carbon-based composite material is used for catalytically degrading various volatile organic compounds such as formaldehyde, benzene, methylbenzene, xylene, phenol, chlorophenol, benzaldehyde, chloroethane, cyclohexane or amyl acetate in a gas phase at room temperature; and results show that the catalytic degradation rate of volatile organic compounds such as methylbenzene, benzene and formaldehyde with a low concentration of 1-5 mg / m<3> within 24 hours is upto 95% or above, and the catalytic degradation rate of methylbenzene, benzene, formaldehyde and the like with a high concentration of 5-10 mg / m<3> within 24 hours is up to 90% or above.

Description

technical field

[0001] The invention relates to a preparation method and a test device of a carbon-based composite material for catalytically degrading volatile organic compounds at room temperature. Background technique

[0002] Indoor air pollution caused by a variety of volatile organic compounds (VOCs) emitted from building decoration and furniture endangers people's health and quality of life, and has become a social issue that people worry about, leaders care about, and the media pay attention to. How to effectively control indoor organic compounds ( VOCs) pollution has also become a research hotspot in the field of indoor air in my country. The use of purification materials to remove organic compounds (VOCs) in indoor air is an important way to solve this problem. Among them, activated carbon adsorption is considered to be a relatively reliable and safe purification method, and it has been widely used in the purification of organic compounds (VOCs) in indoor air. , bu...
