Problems solved by technology

[0004] For gaseous pollutants, the existing technology adopts physical and chemical methods to deal with them, but both of them have deficiencies.
In the physical method, the existing technology uses high specific surface area materials such as activated carbon for physical adsorption. This type of material has a high specific surface area and good adsorption performance, but there is a problem of adsorption saturation; or use precious metals, metal oxide catalysts for physical adsorption Catalysis, that is, the method of chemical catalytic decomposition, but the catalytic process of the catalyst is a chemical process, the rate is relatively slow, and the treatment efficiency of gaseous pollutants is very low in the case of fast air flow

Abstract

The invention discloses a supported catalyst material, which comprises an active component, a catalyst carrier and an activator for activating VOC. The invention provides a supported catalyst material with a pseudo specific gravity of 0.1-2.0 g / mL and a specific surface area of ​​200-1500 m 2 / g, not only has high VOC enrichment ability, but also has good aerodynamic passability, so that the air containing VOC molecules can pass smoothly, and in the case of fast air flow, it can improve the concentration of VOCs such as formaldehyde in the air. Adsorption capacity and handling.

Description

technical field [0001] The present invention relates to the field of air purification, and more particularly, to supported catalyst materials. Background technique [0002] In 2013, with the concentrated outbreak of smog in many cities across the country, the air pollution problem has become a hot social issue, and the market related to indoor air treatment has also grown rapidly in a short period of time. Air quality has become one of the livelihood issues that people are most concerned about. The frequent occurrence of smog weather and the increasing indoor environmental pollution caused by decoration and furniture have led to the birth of the indoor environmental protection industry represented by air and in-car purifiers. It is showing a vigorous development momentum. [0003] In view of the current increasingly severe air pollution situation, it is necessary to research and develop air purification products suitable for China's national conditions. Although the indust...
