Activated Carbon for VOC Removal

What is VOC Gas?

VOC gases refer to Volatile Organic Compounds (VOCs), a class of organic compounds that can evaporate into a gaseous state at room temperature. VOCs are a complex mixture including a variety of chemicals such as benzene, toluene, xylene, ethyl acetate, acetone, etc. VOCs are found in a wide range of substances used in everyday life, such as paints, cleaning agents, office supplies, cosmetics, car exhaust, and tobacco smoke. They can also be released into the air through a number of industrial processes and natural sources.

Activated Carbon for VOCs Removal

VOCs are one of the main components of air pollution and they are not only harmful to human health but also have an impact on the environment and ecosystems. Therefore we need to focus on the treatment of VOCs. Activated carbon is one of the common materials used for disposable VOC adsorption. Activated carbon is a porous material with a high specific surface area and adsorption capacity, which can effectively adsorb VOCs.

How to choose a suitable activated carbon for VOC Removal?

Choosing the right activated carbon material can improve the absorption efficiency and lifetime of a disposable VOC adsorbent. When selecting activated carbon, the following factors need to be considered:

Specific surface area of activated carbon

The larger the specific surface area, the stronger the adsorption capacity, so you need to choose an activated carbon material with a high specific surface area.

Pore size of activated carbon

The pore size directly affects the absorption capacity of activated carbon, and different types of VOCs have different requirements for pore size. In general, the pore size should match the molecular size of the VOCs to maximize adsorption efficiency.

Chemical properties of activated carbon

Different types of activated carbon have different chemical properties and their ability to adsorb different VOCs. Therefore, the appropriate activated carbon material needs to be selected to meet the specific VOCs adsorption requirements.
Notice: different VOCs have different physical and chemical properties and the selection of the appropriate activated carbon material can improve absorption efficiency and lifespan. Therefore, when selecting activated carbon, it should be chosen according to actual needs, and the absorbed material should be replaced or disposed of regularly during use.

Activated Carbon Specifications for VOCs Removal

The choice of activated carbon still needs to be based on factors such as the characteristics of the VOC and the treatment requirements to ensure the best possible treatment. The following table shows the commonly used activated carbon parameters for the treatment of VOCs.
