Application of coal-based activated carbon in environmental protection field

Due to its developed pores, large specific surface area, low price, and excellent adsorption performance, activated carbon has been used in environmental protection fields such as sewage treatment, water purification, VOCs control, desulfurization and denitrification.

There are also many applications in the field of atmospheric management, such as VOCs control, flue gas desulfurization and denitrification, incineration flue gas dioxin removal, H2S removal, indoor air purification, etc.

It can efficiently remove coal-fired flue gas pollutants, and the removal effects of SO2, NO, and VOCs can reach more than 95%, 80%, and 54% respectively. This is mainly because the oxygen-containing functional groups on the surface of the material can remove strong oxidants such as O2. The components decompose and release highly oxidizing O2-, which promotes the degradation of pollutants in flue gas.

Including indoor air deodorization, odor removal, formaldehyde removal, etc. Activated carbon is widely used in indoor air purification due to its rich pore structure and high specific surface area, such as the preparation of environmentally friendly masks, automotive indoor air purifiers, formaldehyde removal, etc. adsorbent.
