Abstract
The adsorption filter according to the present invention is formed from a molded body including activated carbon and a binder, the pore volume of pores having a diameter of 10 μm or greater in terms of the volume of the adsorption filter as measured through mercury intrusion being 0.10 cm3/cc to 0.39 cm3/cc.
Claims20
An adsorption filter comprising a molded body containing activated carbon and a binder,
- wherein a pore volume of pores having a pore diameter of 10 μm or more on a volume basis of the adsorption filter is 0.10 cm3/cc to 0.39 cm3/cc, the pore volume being measured by mercury intrusion porosimetry, and
- wherein a total pore volume on a volume basis of the adsorption filter is 0.50 cm3/cc to 0.73 cm3/cc, the total pore volume being measured by mercury intrusion porosimetry.
An adsorption filter comprising a molded body containing activated carbon and a binder, wherein
- a pore volume of pores having a pore diameter of 7 μm or less on a volume basis of the adsorption filter is 0.15 cm3/cc or more, the pore volume being measured by mercury intrusion porosimetry;
- and
- a total pore volume on a volume basis of the adsorption filter is 0.50 cm3/cc to 0.73 cm3/cc, the total pore volume being measured by mercury intrusion porosimetry.
