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.
