Responding to diversifying needs for electric double layer capacitors
Functional activated carbon
- Sales format
- Granular, powdered, pellet, filter, fiber
Kuraray began production of activated carbon fiber (ACF) in 1980, and commercialized electric double layer capacitors that use ACF fabrics in the 1980s. Since then, we have commercialized fine powder activated carbon (YP, etc.) in response to the diversification of needs for electric double layer capacitors. In addition, we supply products to meet various other needs, including products for electrodes, water purification and deodorization.
Applications
Fine powder activated carbon
Electric double-layer capacitor (EDLC)
Filters (molding carbon filters)
Soluble lead removal, free chlorine removal, trihalomethane removal, mold odor removal, malodorous substance removal
Activated carbon fiber
Electrodes, solvent recovery materials,
odor removal filters, clean water filters
sanitary materials
Impregnated activated carbon
Water purifiers, freshness-retaining materials, deodorizing materials, ammonia removal, trimethylamine removal, formaldehyde removal, acetaldehyde removal
Characteristics
Fine powder activated carbon
Pores are highly controlled according to application.
Various forms are available from granularity to micrometer-scale powders.
Filters (molding carbon filters)
Broad adsorption performance due to approproate activated carbon composition.
Excellent characteristics and long life at high flow rate.
Appropriate as a preprocessing filter dur to minimal fine particle generation.
Activated carbon fiber
Pore size can be adjusted for a wide range of adsorptivity conditions.
Ideal permeability and good particulate removal.
Superb adsorption speed.
Impregnated activated carbon
Impregrated activated carbon has unique functions due to particular chemical treatment.
