It is known that activated carbon fibers are mainly produced. This greatly improves the drawbacks of paper containing powdered or granular activated carbon as mentioned above, but it is difficult to obtain paper with uniformity, and when paper is mixed with other fiber materials, it is difficult to obtain uniform paper. I was only able to obtain paper with large irregularities. Furthermore, since activated carbon fiber has a high rigidity, it is difficult to make paper with a high density, and only thick paper can be made.
以上のごとき事情に鑑み厚みが小さく密度の高
い活性炭素繊維シートを得るべく鋭意研究を行な
つた結果本発明に到達したのである。 In view of the above circumstances, the present invention was achieved as a result of intensive research aimed at obtaining an activated carbon fiber sheet with a small thickness and high density.

ある。 The present invention involves dispersing fibrous activated carbon and other fibrous materials with an average fiber length of 0.5 to 10 mm and a crimping rate of 3% or less expressed by the following formula in water in a weight ratio of 1:0.1 to 1:1, This is a method for producing activated carbon fiber paper.

% or less, the thickness must be 0.2mm or less,
The fibrous activated carbon must meet four conditions: a density of 0.15 to 0.30 g/cm 3 . When the fiber length is less than 0.5 mm, the yield of fibrous activated carbon in paper making is poor, the resulting paper lacks uniformity of the mixed fibers, the paper strength is weak, and the paper falls off during processing or use. Furthermore, when the fiber length exceeds 10 mm, the resulting paper has a low density and has large density unevenness and mixed paper unevenness. When the crimping rate is greater than 3%, paper with high density cannot be obtained, resulting in large density unevenness and poor paper formation. Furthermore, since the water quality during paper making is poor, productivity is not only poor, but also the paper is dried without sufficient dehydration, resulting in a decrease in the adsorption properties of the paper.

活性化処理されることにより製造される。 Fibrous activated carbon that satisfies the above properties can be produced by the following method. Manufactured by carbonizing recycled cellulose fibers, novolac crosslinked fibers, etc. with an average fiber length of 1 to 20 mm that are virtually crimped, and then activating them at a temperature of 800°C to 1000°C in an atmosphere containing steam. .

用上不都合である。 Next, examples of fibers to be mixed with fibrous activated carbon include natural fibers, synthetic fibers, organic fibers, and inorganic fibers. That is, they include natural fibers such as wood pulp, hemp pulp, and linter pulp, semi-synthetic fibers such as rayon, synthetic pulps such as polyacrylonitrile, polyethylene, and polypropylene, and inorganic fibers such as asbestos fibers. These may be used alone or in combination of two or more. These mixed fibers are
It is necessary to mix in a weight ratio of 0.10 to 1.0 times that of activated carbon fiber paper. If the amount of mixed fiber is larger than this, a sheet with the desired high adsorption capacity cannot be obtained, and if the amount of mixed fiber is smaller than this, the mechanical strength of the obtained sheet will be low, which is disadvantageous in practice. .

In some cases it may be preferable.

The activated carbon fibers are disintegrated with a pulper and put into a mixing tank, and then the fibers to be mixed are also disintegrated with a pulper and put into a mixing tank. The concentration of fibers in the mixing tank is usually 0.5-3%. After adding various auxiliary agents to this mixing tank, the mixture may be filtered through a normal paper-making wire mesh, such as a circular wire mesh or a fourdrinier, and then dried in a Yankee type or multi-barrel dryer.

吸着処理を行うことが出来る。 According to the present invention, it is possible to obtain activated carbon fiber paper which has no density unevenness or mixed paper unevenness and has a high density.The paper obtained by the present invention is homogeneous and has high adsorption properties, so it can be used as an adsorption sheet or other material. Although this is useful, it is particularly effective when used in a parallel flow adsorption system in which the gas to be treated is caused to flow parallel to the adsorption sheet and be adsorbed. The speed of movement of adsorbed gas molecules within activated carbon fiber paper is uniquely proportional to the reciprocal of the thickness of the paper, so the thinner the paper, the higher the adsorption speed. According to the present invention, activated carbon fiber paper with a high density can be obtained, so the thickness of the paper can be reduced, and the adsorption speed is high, so the activated carbon fiber paper of the present invention can be used to create a honeycomb structure and a corrugated structure. When an adsorbent is produced, the thickness of the adsorption zone (minimum path length required for adsorption) can be made small, and gas adsorption processing can be performed with low pressure drop.

わされる。Ｋは比例定数である。 That is, a test piece was sandwiched between two glass plates with a diameter of 30 cm, and a light beam focused on the paper surface was used to measure the diameter of the specimen.
Irradiates with a luminous flux of 0.2mm. A phototube is placed on the opposite side of the paper to receive the transmitted light. When the average current of the phototube is ζ and the root mean square of the deviation between the average current and the alternating current component is σ, the formation index a is expressed by the following equation. K is a proportionality constant.
ａ＝Kσ／
ａの数値の高いほど地合不良であることを示
