Abstract

PROBLEM TO BE SOLVED: To obtain active carbon excellent in molecular sieve effect and adsorptive removing performance by binding or coating carbon black as the major component with carbon. SOLUTION: This active carbon is obtained by adsorbing a resin to carbon black followed by heat treatment in a nonoxidative atmosphere to carbonize the resin. By the heat treatment, the carbon black particles are mutually bound via carbon or coated with carbon. For the carbon black, various kinds thereof can be used; for example, carbon black 10-70 nm in primary particle size. The resin to be used is e.g. a styrene-acrylic resin, polyester resin, epoxy resin. This active carbon can be produced, for example, by the following process: the resin is dissolved in a solvent followed by adding the carbon black to the resultant solution which, in turn, agitated and then subjected to a beads mill into a mill base dispersion; subsequently, the dispersion is put to centrifugal classification, and the resulting precipitate is dried to remove the solvent, and then baked in a nonoxidative atmosphere.

(Consideration of Table 1) As is clear from the results of Table 1, Comparative Example 1 produced by the conventional starting material and the production method was used.
The activated carbons of Examples 1 to 3 which fall within the scope of the present invention as compared with the commercially available activated carbons of Examples 1 and 2 have extremely high red dye adsorption characteristics. The specific surface area and the median pore diameter measured by nitrogen gas adsorption are small. The pore diameter is rather large, and the specific surface area is a considerably small value. This means that the activated carbon within the scope of the present invention has a large specific surface area like the commercially available activated carbons of Comparative Examples 1 and 2, that is, at many active points. It has been shown that the adsorption elimination performance and the molecular sieving effect are exhibited by controlling the pore size of the activated carbon instead of causing the adsorption phenomenon. Further, Examples 1 to 3 which are the scope of the present invention are as follows.
As compared with the carbon black alone of Comparative Example 3,
The median pore diameter and the adsorption removal performance were clearly different, and it was found that the raw material carbon black and the activated carbon in the present invention had clearly different physical properties and the like.
