Activated carbonaceous honeycomb body and production method thereof

An activated carbonaceous honeycomb body is prepared by extruding a tempered mass containing a thermosetting resin such as phenol resin, drying and solidifying the green honeycomb body, preheating the same in a nonoxidizing atmosphere at a heating rate of 30 DEG C./hr or lower to a temperature between 500 DEG and 1,100 DEG C. until the hydrogen content of the resulting C-matrix has been lowered to 2% or less, and then heating the thus-preheated honeycomb body in an activating atmosphere to a temperature between 600 DEG and 1,000 DEG C. until the ratio of the total thickness of resulting activated carbon layers to that of the remaining glassy carbon layer in the thickness direction of each wall of the honeycomb body has reached a value not greater than 30. The activated carbonaceous honeycomb body exhibits good refractoriness and thermal shock proofness as well as pertains excellent strength, particularly, against compression forces. Accordingly, it can be effectively used as a catalyst support, adsorbent or filter.
