Activated Carbon Fiber is an excellent functional adsorbent material due to its high porosity
and large surface area. It can be made into many different patterns such as felt, cloth
and other fabric. Activated carbon fiber has many advantages over other forms of activated
carbon such as Powered Activated Carbon because of its unique shape, and is widely used in a
multitude of applications including environmental (carbon fiber filters for air purification and
water treatment), chemical (recovery of organic solvents and compounds), and military
defense (gas masks and fire-resistant clothing).  

Advantages of HPMS Activated Carbon Fiber

- Highly developed micro-pore structure (< 2nm).
- Outstanding regeneration and degeneration process due
to its large surface area.
- Ability to reach expectable efficiency quickly.
- Extremely rapid and efficient adsorption and
desorption rates.
- Excellent absorption to low concentration substances.
- Tensile strength allows activated carbon fiber to be made into many different patterns.
- Acid resistant and Alkaline resistant.
- Highly heat resistant, great electric conductivity, and chemically stable.
- Low ash content
- Design flexibility
- Relatively low cost associated with much higher yield.
- When used for filter systems, lightweight and less bulky compared to those made with
Granular Activated Carbon
-  Many advantages over powdered forms of activated carbons: form-fitting property allows it
to be fabricated into many available shapes (activated carbon cloth, felt, and paper) to meet
any unique requirements in application, greater capacity and higher speed in performing
adsorption and desorption, and secondary contamination is not a concern.

Applications

- Recovery of Organic Compounds and Solvents
Activated carbon fiber is widely used for recovering organic compounds and solvents (up      
to 97% recovery) as adsorption and desorption are extremely quick and efficient. Filters         
that contain activated carbon fiber can also be used in compressed air and gas purification to  
remove oil vapors, odors, and other hydrocarbons in the air.

-
Air purification and carbon filter material
Activated carbon fiber is frequently used to make activated carbon filters that can         
eliminate foul smelling odors in the air. Activated carbon fiber can also be used to                   
remove harmful particles and contaminates such as carcinogens, exhaust, and other               
pollutants (such as formaldehyde, toluene, hydrogen sulfide and ammonia).

-
Wastewater treatment
Activated carbon fiber can be used to treat phenolic wastewater and medical waste.

-
Drinking water purification
Activated carbon fiber is frequently used for water treatment as well as for distilled                
alcoholic beverage purification. Activated carbon fiber filters can be used to filter beverages   
such as vodka and whiskey with organic impurities to improve odor, color, and taste.  

-
Military Defense / Clothing
Activated carbon fiber can be used in many applications of military defense, such as for
Biological and Chemical (NBC) protective clothing: it has the same basic characteristics as
clothing (including strength, flexibility, and endurance). It can also be easily cut into different
sizes and shapes.

-
Protective Masks
Activated carbon fiber can be used for gas masks that filter poisonous gas such as benzene
and carbinol.

-
Refrigerator deodorizer
Activated fiber carbon can be used to remove odors and keep food refresh in                         
refrigerators.

- Other
Activated Carbon Fiber can be made into anti-corrosive and heat insulating material.
