Abstract

An active carbon molded body that comprises a plurality of active carbon granules that are formed from aggregates of active carbon particles. The active carbon granules include a fibrous granulation binder. The active carbon molded body is formed as a result of the plurality of active carbon granules being aggregated by means of the fibrous granulation binder in the active carbon granules. The present invention is also an active carbon molded body production method in which active carbon granules that have been formed by aggregating active carbon particles by means of a fibrous binder are molded by simultaneous application of heat and pressure without separate addition of a molding binder. The present invention thereby provides: an active carbon molded body that has high purification capacity and good production efficiency; and a production method for the active carbon molded body.

Claims (13)

1. An active carbon molded body comprising a plurality of active carbon granules,

wherein the active carbon granule comprises an aggregation of active carbon particles and a fibrous binder, the plurality of active carbon granules is aggregated by the fibrous binder included therein,

the active carbon molded body is obtained by molding the plurality of active carbon granules by the fibrous binder,

the active carbon molded body comprises no molding-purpose binder other than the fibrous binder,

the active carbon molded body includes the fibrous binder in an amount of 6 wt % or more and 20 wt % or less, and

a density of the active carbon molded body is 0.4 g/cc to 0.5 g/cc.

2. The active carbon molded body according to claim 1 , wherein the active carbon granule consists of the aggregation of active carbon particles and the fibrous binder.

3. The active carbon molded body according to claim 1 , wherein a density of the active carbon molded body is 0.46 g/cc to 0.5 g/cc.

4. The active carbon molded body according to claim 1 , wherein the fibrous binder includes an acrylic material.

5. A method for producing an active carbon molded body, the method comprising:

obtaining a plurality of active carbon granules by aggregating active carbon particles by a fibrous binder;

aggregating the active carbon granules by the fibrous binder included in the active carbon granules; and

molding the active carbon granules aggregated, by simultaneous application of heat and pressure.
