RECOVERY METHOD FOR ORGANOCHLORINE SOLVENT

摘要

PROBLEM TO BE SOLVED: To provide a recovery method for an organochlorine solvent which has excellent efficiency and hardly causes corrosion of an apparatus.

SOLUTION: In the recovery method for the organochlorine solvent, fibrous activated carbon having the following specifications is used as the adsorbent: (a) the equilibrium adsorption moisture content is 1.0-15.0 %, (b) the BET specific surface area is 500-2,500 m2/g, (c) the micropore volume is 0.25-2.00 cc/g, (d) the volume of the micropores having micropore radii measured by the water vapor method of the range 6-16 Å is 80% or more of the volume occupied by the micropores having micropore radii of ≤100 Å and (d) the graphite crystalline structure parameter Ip/Io at a diffraction peak of the face (002) on X-ray diffraction intensity curve is ≤0.35.
