<p><P>PROBLEM TO BE SOLVED: To provide an activated carbonized material which opens the way to effectively utilize cock feathers generated in large quantities every year, has a large specific surface area and a pore distribution based on mesopores of 2-50 nm, and is suitable for use as a gas phase adsorbent suitable for deodorization, purification, gas separation and the like, as a liquid phase adsorbent suitable for wastewater treatment, water purification and the like, as an enzyme and microorganism immobilization carrier, and as a material of a large-current and large-capacity electric storage device. <P>SOLUTION: The activated carbonized material is obtained by impregnating an alkali solution into a crushed product of cock feathers having an average diameter of 50-2,000μm and subjecting the crushed product to activation carbonization treatment at 700-850°C in an inert gas atmosphere. The activated carbonized material has a specific surface area of 2,300-3,200 m<SP>2</SP>/g, a mesopore (whose width is 1.5-2.5 nm) volume of 1-2 mL/g and an average pore diameter of 1-3 nm. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
