Abstract: Disclosed herein are activated carbons having a high decolorization performance in a liquid phase, and methods for producing the activated carbons. Disclosed herein are also activated carbons having a high decolorization performance in liquid phases having relatively high viscosities, such as sugar liquids, and methods for producing the activated carbons. Activated carbons disclosed herein include activated carbons having a pore volume, which is calculated by measuring a nitrogen adsorption isotherm at 77 K and performing the MP method analysis, of 0.58 mL/g or less, and having a pore volume at a pore diameter of 10 to 10000 nm measured by the mercury intrusion method of 0.35 mL/g or more.

Abstract: Disclosed herein are activated carbons having high decolorization performance in liquid phases, especially in liquid phases having relatively high viscosities, such as sugar liquids, and methods for producing the activated carbons. Activated carbons disclosed herein include activated carbons having a pore volume at a pore diameter of 10 to 10000 nm measured by the mercury intrusion method of 0.8 to 1.9 mL/g, and having a pore volume at a pore diameter of 300 to 1000 nm measured by the mercury intrusion method of 0.19 mL/g or more.

Abstract: The present invention relates to a coconut shell-derived modified activated carbon having a BET specific surface area of 1400 to 2000 m2/g, a value of hydrogen content/carbon content of 0.0015 to 0.0055, and intra-skeletal oxygen of 0.9 mass % or less.

Abstract: The present invention relates to an activated carbon, having a pore volume (A) of 0.3 to 0.7 mL/g at a pore diameter of 6.5 to 50 nm as determined by mercury intrusion porosimetry, a pore volume (B) of 0.23 mL/g or less at a pore diameter of 750 to 4,000 nm as determined by mercury intrusion porosimetry, and a pore volume ratio (A)/(B) of 1.7 or higher.
