KURACTIVE
１.Activated carbon fabric KURACTIVE
Kuractive is new activated carbon fabric developed by Kuraray Chemical noted for a leading
integrated activated carbon manufacturer in Japan. Kuractive, made from special synthetic
fiber comprising of three types, namely, fiber, felt, and cloth , has large variety of
adsorption performance.
By applying Kuractive, the compact equipments can be manufactured for various adsorption
uses. Activated carbon fabric is the third activated carbon appeared next to granular and
powdered type. Particularly, cloth type attracts attention for use as capacitor.
Kuraray Chemical which is manufacturing Kuraray Coal (activated carbons made of coconut
shell charcoal and coal), Kurasheet (activated carbon-impregnated urethane foam), and
supplying “Kuractive”, has been consistently making efforts to develop superior products
to meet diversified requirements from customers.

２．Distribution of Pore Size
In ordinary activated carbons, macro pores are composed outside surface at first, then
transitional pores and micro pores are orderly made inside. In case of Kuractive, only
specific micro pores are uniformly developed inside, resulting to extremely sharp
distribution of pore size.

３.Characteristics of KURACTIVE
1. Large surface area (800～2000m2/g) and high adsorption capacity.
Kuractive has wide range of adsorption capacity and volume.
2. Optionally controlled pore size and volume.
Pore of granular activated carbon are formed by macro pore, transitional pore,
micro pore in the order of close to exterior. However, Kuractive is formed by
developed micro pore directly to exterior, so it has advantage of sharp pore
distribution.
3.
Rapid adsorption and desorption speed.
Kuractive have advantages not only adsorption speed, but also desorption speed.
In particular about organic solvent, Kuractive is very effective as application
of solvents recovery. Because Kuractive has characteristic to desorb the object
with a temperature near its boiling point.
4.
Remarkable molecular sieving effect.
5.
Exceptionally high purity.
Kuractive is also suited to liquid phase for the good reason that it is high-purity
substance and has impurity like ash barely.
Additionally, Kuractive has high resistance characteristic toward heat, acid and
alkali.
6.
Lower pressure drop.
Kuractive don’t need much adsorption layer because of rapid adsorption speed.
So you can set up equipment that has less pressure drop.
