Abstract

PURPOSE:To inhibit the adsorption of a material, etc., before a stage for using active carbon, and to obtain an active carbon product having superior preservability and formability by impregnating a monomer for forming depolymerizable polymer into pores of the active carbon and polymerizing the impregnated monomer. CONSTITUTION:A monomer (e.g. styrene, propylene) which forms depolymerizable polymer is impregnated into pores of active carbon. An aimed active carbon product is obtd. by polymerizing the monomer. By this method, the depolymerizable polymer functions as plug for the pores in the preservation stage of the active carbon, inhibiting thus the adsorption of a material. The polymer serves also as a reinforcing body for the active carbon, preventing the crumbling of the active carbon. When the active carbon is used for adsorption, the depolymerizable polymer impregnated in the pores is removed easily by heat-treatment, etc.

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to activated carbon products and methods for producing the same. The use of active materials, such as those that are kneaded with a binder such as a resin and molded by injection molding or extrusion molding, and then subjected to heat treatment to form a skeleton of the binder. It is particularly suitable for those that are subjected to heat treatment.

(Prior art) Activated carbon used not only as it is, but also when making activated carbon molded products as described above, is usually not subjected to any special treatment, but is simply obtained as activated carbon. I was using things as they were. Some also disclose the use of activated carbon whose surface is coated with something that forms communicating pores that are larger than the binding material skeleton. For example, JP-A-60-96516 discloses the use of activated carbon whose surface is coated with a material having a relatively low carbon yield.

In other words, various substances are adsorbed into the pores of activated carbon, causing performance deterioration over time, and activated carbon is generally easy to crumble due to its strength.Furthermore, during molding, it is difficult to use plasticizers, solvents, etc. The moldability deteriorates due to impregnation of the molding aid into the pores. If a large amount of these molding aids is used in order to improve moldability, the shape stability of the molded product will deteriorate and the strength of the molded product will also be significantly reduced. Regarding this point, the same applies when using activated carbon whose surface is coated with a material having a relatively low carbon yield. This is because even if the activated carbon surface could be completely covered.

(Means for solving the problem) Fill the pores with a depolymerizable polymer. Examples of depolymerizable polymers include polyethylene polypropylene, polybutadiene, polyinobutylene, polystyrene, nylon, polymethacrystyrene, polymethyl methacrylate, polyethyl methacrylate, poly-alpha-toiterostyrene, etc. Methyl acid is one of the particularly preferred. The degree of depolymerization is extremely high.

In addition, in order to impregnate the pores with the depolymerizable polymer, it is possible to immerse activated carbon in a diluted solution of the depolymerizable polymer with a solvent and dry it, but the filling amount is preferably larger. It is best to set the amount to 20% (volume) or more, since this method is troublesome, such as having to process repeatedly and even then not being able to fill much.

Generally known polymerization methods can be used as they are. That is, simply heated polymerization catalysts such as hydrogen peroxide, ammonium persulfate, benzoyl peroxide, cumene hydroperoxide, azoisopistintyronitrile, dimethylaniline, metal complex salts, etc., or the use of light such as ultraviolet rays. There are various methods depending on the method using energy and the type of impregnating monomer. In addition, for impregnation, microvibration by ultrasonic waves, forced means such as heating or reduced pressure may be used.
