<P>PROBLEM TO BE SOLVED: To provide an adsorbent which is composed mainly of silica/alumina with the capability of efficiently adsorbing even a volatile chemical substance which is hardly water-soluble, and to provide a method for manufacturing this kind of adsorbent. <P>SOLUTION: The adsorbent is manufactured through the following three processes: that is, (1) a mixing process to prepare a raw material mixture by mixing a waste molding sand containing a carbon component with a calcium phosphate compound and a dispersion medium, (2) a molding process to make a molded form of a desired shape by molding and drying the raw material mixture, and (3) a calcining process to obtain a calcined product containing carbon by calcining the molded form in a reducing atmosphere. These series of the processes can obtain the adsorbent as a calcined product containing the carbon with an excellent adsorption activity while preventing the carbon component from being lost. <P>COPYRIGHT: (C)2011,JPO&INPIT |
