Abstract:
1. An activated carbon having an average length/average diameter (L/D) of 0.8 to 1.2 and a difference between the 1/1-volume benzene adsorption rate and the 1/10-volume benzene adsorption rate of 8.6 g/100 mL or more; wherein the 1/1-volume benzene adsorption rate is a product obtained by multiplying the volume-based equilibrium benzene adsorption capacity (%) that is obtained using 1/1 benzene vapor for calculation in accordance with JIS 1474 5.12 by the packing capacity (g/100 mL) that is obtained in accordance with JIS 1474 5.7, and the 1/10-volume benzene adsorption rate is a product obtained by multiplying the volume-based equilibrium benzene adsorption capacity (%) that is obtained using 1/10 benzene vapor for calculation in accordance with JIS 1474 5.12 by the packing capacity (g/100 mL) that is obtained in accordance with JTS 1474 5.7.
