Activated Carbon Fiber & Felt

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 activated carbon felt, activated carbon cloth, and other activated carbon fabric.

Activated carbon is also called activated charcoal and the two can be used interchangeably. Activated Carbon Fiber is an effective material for purifying water and removing odors and volatile organic compounds.

Activated carbon fiber has many advantages over other forms of activated carbon, such as Powdered Activated Carbon, because of its unique properties and form factor. It 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 Graphite 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 adsorption of low concentration substances.
  • Tensile strength allows activated carbon fiber to be made into many different patterns.
  • Acid resistant and Alkaline resistant.
  • Highly heat resistant, excellent electric conductivity, and chemically stable.
  • Low ash content.
  • Design flexibility. Available as an activated carbon sheet or as an activated carbon roll.
  • Relatively low cost associated with a much higher yield.
  • Lighter and less bulky when used for filter systems when 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 filter sheets and activated carbon filter / filtration systems that can eliminate foul-smelling odors in the air. Activated carbon fiber can also remove harmful particles and contaminants 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 and for distilled alcoholic beverage purification. Activated carbon fiber filters can 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 military defense applications, such as for Nuclear, 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.
