Adsorptive material

An adsorptive member consisting essentially of multi-layers of corrugated board wherein the channels of the corrugations are arranged in substantially the same direction so as to permit a fluid flow through the channels along the corrugations, each layer consisting essentially of a corrugated material bonded on at least one surface thereof with a flat sheet of material, said corrugated board containing active carbon fiber in an amount of at least 10% by weight and having a volume density of at least 0.06 g/cc, said carbon fiber having the characteristics of an equilibrium adsorption amount of benzene of not less than 200 mg/g and a benzene adsorption rate of not less than 0.2 min.sup.-1.

A continuous rotary-type adsorption apparatus which comprises a chamber containing an adsorption zone and a desorption zone, means for introducing and removing the fluid to be adsorbed, into and out of the adsorption zone, means for introducing and removing a desorbing fluid into and out of the desorbing zone and an adsorptive member rotatably disposed within said chamber, said adsorptive member being adapted to be alternately exposed to said adsorption zone and desorption zone as it is rotated in said chamber, thereby adsorbing the material to be adsorbed from the fluid being treated in the absorbing zone and regenerating the adsorptive member in the desorbing zone, said adsorptive member comprising multiple layers of corrugated board containing active carbon fiber in an amount of at least 10% by weight and having a volume density of at least 0.06 g/cc, and being arranged in said chamber in such a manner that the fluid flows along the corrugations, said carbon fiber having the characteristics of an equilibrium adsorption amount of benzene of not less than 200 mg/g and a benzene adsorption rate constant of not less than 0.2 min.sup.-1.

A process for adsorbing materials containing a fluid utilizing an adsorption zone and a desorption zone, which comprises introducing and removing the fluid to be adsorbed into and out of the adsorption zone, introducing and removing a desorbing fluid into and out of the desorbing zone, and exposing an adsorptive member alternatively to said adsorption zone and desorption zone, thereby adsorbing the material to be adsorbed from the fluid being treated in the adsorbing zone and regenerating the adsorptive member in the desorbing zone, said adsorptive member comprising multiple layers of corrugated board, each layer consisting essentially of a corrugated material bonded on at least one surface thereof with a flat sheet of material said corrugated board containing active carbon fiber in an amount of at least 10% by weight and having a volume density of at least 0.06 g/cc, said carbon fiber having the characteristics of an equilibrium adsorption amount of benzene of not less than 200 mg/g and a benzene adsorption rate constant of not less than 0.2 min.sup.-1, said fluid being supplied along the corrugations and through the channels of said corrugations.
