At present, activated carbon fibers are widely used as a deodorizing material for various pollutant gases because they have the advantages of high specific surface area, fast adsorption rate, handling and processability.
In addition, activated carbon with metal ions impregnated is also known as a deodorant because it improves its function. For example, a deodorant obtained by impregnating active manganese dioxide produced by adsorbing a potassium permanganate solution on activated carbon has an excellent ability to adsorb malodorous gas as compared with ordinary activated carbon.

【発明が解決しようとする課題】活性炭に薬剤を添着し

によって塞がれるなどが原因となっていると思われる。
一方、触媒黒鉛化の技術は難黒鉛化材料を比較的低温で
黒鉛化できる点で優れているものである。The deodorant carried by impregnating chemicals on activated carbon has a tendency to deteriorate its deodorizing ability rapidly because the impregnated chemicals are likely to deteriorate due to use. It has the drawback of being time-consuming. In recent semiconductor factories, the level of pollution prevention in the environment has increased with the increase in the degree of integration, and it has become difficult to cope with even ordinary activated carbon fibers. Whether it is granular or fibrous, the deterioration of the deodorizing ability of the impregnated type activated carbon is remarkable because the drug is not supported on the pore surface, or even if it is supported, the pores are blocked by the drug. Seems to be the cause.
On the other hand, the technique of catalytic graphitization is excellent in that it can graphitize a non-graphitizable material at a relatively low temperature.

No research has so far been proposed on the relationship between the catalytic substance and the deodorizing ability of the carbonaceous material.
【０００７】従って、本発明は、改良された新規な脱臭

実を鑑み、新しい活性炭系の吸着剤の開発につき、鋭意

在させて焼成炭化し、賦活処理した活性炭が優れた脱臭
能を有することを知見し、本発明を完成した。In view of the above facts, the present inventors have earnestly studied the development of a new activated carbon-based adsorbent, and as a result, have made a manganese compound preexist in an activated carbon precursor to perform carbonization by firing. Then, they found that the activated carbon which had been activated had an excellent deodorizing ability, and completed the present invention.
【０００９】即ち、本発明が提供しようとする脱臭性活
性炭は、マンガン触媒の存在下で炭素化及び賦活された
マンガン担持活性炭を有効成分とすることを構成上の特
徴とする。That is, the deodorizing activated carbon to be provided by the present invention is characterized in that it contains manganese-carrying activated carbon carbonized and activated in the presence of a manganese catalyst as an active ingredient.

The structural feature is activation treatment.

であって、マンガン成分は活性炭中で均質に存在してい
るものである。The deodorizing activated carbon according to the present invention is a manganese-supporting activated carbon, but is basically different from the conventional activated carbon impregnated with manganese. That is, the manganese-supporting activated carbon in the present invention is carbonized and activated in the presence of a manganese catalyst. Here, in the presence of a manganese catalyst, carbonizing and activating means that a mixture of an organic compound which is a precursor of activated carbon and a manganese compound is carbonized and activated by a conventional method as described below. Thus, the manganese component is present homogeneously in the activated carbon.
【００１２】そして、マンガン成分の状態は、含有量に

在しているものと推定される。Although the state of the manganese component is not clear depending on the content, as shown in FIG. 2, for example, in the case of manganese-supporting activated carbon having a manganese content of 5.2% by weight as Mn, XRD shows 35 °, 40
From the fact that the diffraction lines are seen at around 90 ° and 59 °, it is presumed that it probably exists in the form of crystalline manganese lower-order oxide such as MnO.

有量に対して脱臭能が飽和傾向を示すのみならず、むし
ろ、マンガン担持活性炭の物性、例えば繊維状にあって
は強度の劣化など好ましくない傾向を示すからである。The content of the manganese component in the manganese-supporting activated carbon is not uniform depending on the manufacturing conditions of the manganese-supporting activated carbon and the deodorizing use, but is 0.1 to Mn.
It is in the range of 15% by weight, preferably 0.5-10% by weight. The reason for this is that if it is less than about 0.1% by weight, the improvement of the deodorizing effect is insufficient, while if it exceeds about 15% by weight, not only the deodorizing ability tends to be saturated with respect to the content, but also the manganese is rather increased. This is because the physical properties of the supported activated carbon, for example, in the fibrous state, the unfavorable tendency such as deterioration of strength is exhibited.

維が最も好ましいと言える。The deodorizing activated carbon according to the present invention may be in the form of powder or compact depending on the purpose of use.
The particle size of the powder is not particularly limited, and the molded body may take any form such as granular, fibrous, and honeycomb body. However, it can be said that the activated carbon fiber is most preferable except the economical aspect.

Manganese acetate or the like is preferable, and it is used as an aqueous solution or a solution state using an organic solvent such as methanol, ethanol, acetone or benzene. If necessary, a solution containing copper or silver ions may be used in combination.

しながら均一に、吸着、含浸処理する。These two raw materials are mixed in a desired container to obtain a uniform raw material mixture. Therefore, if the organic substance is also soluble in the organic solvent, it is desirable that the organic substance is mixed in the form of a solution. In addition, an organic substance that does not dissolve in a desired organic solvent is immersed or added in a manganese solution, and then uniformly adsorbed and impregnated while stirring.

を紡糸した後、炭素化及び賦活することも好ましい。Next, after the solvent is separated and removed, the obtained formulation is subjected to carbonization and activation treatment by a conventional method to obtain activated carbon. In this case, in the case of activated carbon fiber, it is also preferable to spin the raw material mixture, and then carbonize and activate it.

て、特に常法と異なる手段をとる必要はない。Carbonization is carried out by firing at a temperature of 600 to 1000 ° C. in a non-oxygen gas stream such as nitrogen gas, and activation is carried out by steam using nitrogen gas as a carrier gas at 600 to 1000 ° C.
It is carried out by heating under the temperature of, and in the present invention, it is not necessary to take a means different from the usual method.

It can be effectively applied to fields that could not meet the above requirements.

推定できる。The deodorizing activated carbon according to the present invention contains manganese-supporting activated carbon obtained by carbonizing and activating an organic substance containing a manganese compound as an active ingredient. Therefore, unlike the conventional method of impregnating activated carbon with manganese activated carbon,
Since the supported manganese component is evenly present in the activated carbon, the pores of the activated carbon are not blocked by the loading of the manganese component, and have the same pores and specific surface area as ordinary activated carbon. In particular, manganese-supporting activated carbon fiber has little deterioration in deodorizing ability and can be applied as a very excellent deodorant. Further, it can be estimated from the XRD measurement that the supported manganese component is a very fine crystalline low-order oxide (MnO).
