Activated carbon fiber application

[Application] ACF is suitable for the treatment of various organic wastewater, and can treat chlorine-containing wastewater, pharmaceutical factory wastewater, organic dye wastewater, papermaking black liquor, phenol wastewater, tetraphenyl wastewater, caprolactam wastewater, dimethylacetamide and isobutanol Waste water is treated

(1) Dye wastewater

ACF can remove methylene blue, crystal violet, odor phenol blue and other organic dye molecules in the water, with large adsorption capacity and high removal rate

Zhemin Shen et al.

(2) Papermaking black liquor

Jia Jinping conducted a research on the application of ACF electrode method for electrolytic treatment of papermaking black liquor, and found that when the pH was about 7 and the electrolysis was 80 minutes, the removal rates of COD and chroma reached 64.

(3) High-priced heavy metal ion wastewater

Research by RFu et al.

After the 13 morpholine pesticide wastewater and oil refinery wastewater are treated by ACF, the removal rate of COD reaches 94% and 88.

The adsorption characteristics of activated carbon fiber are as follows:

①Narrow and uniform pore size distribution.

Due to the small pores and uniform pore size distribution, there is a strong interaction between ACF and adsorbate molecules

②The precursor of ACF with small and uniform fiber diameter is carbon fiber

Many studies have reported the penetration curves of VOCs in ACF and GAC fixed beds, and compared them with GAC fixed beds

Suzuki studied the axial diffusion behavior of the ACF bed

③ Graphitized structure, high conductivity and high strength.

However, the resistivity of ACF cloth and fabric is relatively high

Due to the high conductivity of ACF, the adsorption bed can be regenerated by electric heating.

Activated carbon fiber has high tensile strength, so it can be processed into various forms such as cloth, fabric, paper, felt and composite materials

Activated carbon fiber monolithic composite materials made of phenolic resin as a binder may be used in many aspects including gas separation
