【発明の詳細な説明】
本発明は、耐熱材料製の短繊維からなる触媒担
体に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a catalyst carrier consisting of short fibers made of a heat-resistant material.
理想的な触媒の条件は、その表面積が無限大で
あること及びその熱容量が最小であることであ
り、この２点が理想的である場合に最高の活性が
得られるものである。しかし、この理想的条件に
合うものは極微細粉末の形態となるものであり、
その結果、空中に散乱し固定することが不可能で
あるため、何等かの担体を利用し、その担体表面
に触媒を担持させる必要がある。 The ideal catalyst conditions are that its surface area is infinite and its heat capacity is minimum, and when these two points are ideal, the highest activity is obtained. However, those that meet this ideal condition are in the form of ultrafine powder,
As a result, it is scattered in the air and cannot be fixed, so it is necessary to use some kind of carrier and to support the catalyst on the surface of the carrier.

ガラス繊維を使用する触媒を発表し（特公昭53―
38264号）、更に、このガラス繊維の表面に均一な
フイルム状の触媒成分を担持させる方法を発表し
た（特公昭51―21629号）。 Traditional catalyst supports are granular pellets (3000 microns in diameter) and refractory honeycombs (200 microns thick).
etc. are used. However, the heat capacity of the carrier relative to the surface area of the catalyst, that is, there are many parts that do not come into contact with the processing gas and are not actually effective, so there is a drawback that the starting performance of the catalyst is poor. In this regard, the use of fibers made of heat-resistant materials such as glass fibers as carriers has the advantage of superior startability due to their small diameter (10 microns or less), large surface area, and small heat capacity. The present inventors focused on this point and first announced a catalyst using heat-resistant glass fiber as a carrier (Japanese Patent Publication No.
38264), and furthermore, they announced a method for supporting a uniform film-like catalyst component on the surface of this glass fiber (Japanese Patent Publication No. 51-21629).
前述の理想的な触媒条件に従えば、繊維の直径

減少するから、この繊維に触媒成分を担持させた
場合、触媒活性が向上する結果となる。しかし、

してこのような短繊維は、工業的に触媒担体とし
て製品化することが困難となる。 According to the above-mentioned ideal catalyst conditions, the smaller the diameter of the fiber, the more the surface area per unit weight increases, while the heat capacity per unit surface area decreases, so when this fiber supports a catalyst component, This results in improved catalytic activity. but,
Glass fibers manufactured today have a minimum diameter of 6 microns in the form of endless long fibers (6 microns is the general limit, although some in the United States have diameters up to 3 microns), It has not reached 5 microns or less, where the skin will not be irritated. If you want a thin fiber of 5 microns or less (0.5 to 3 micron diameter), the fiber length is 5 to 10
It becomes short fibers of mm or less. Such short fibers are difficult to industrially commercialize as catalyst carriers.

るかが最大の問題点である。 Today, many fibers made of heat-resistant materials with a diameter of 3 microns or less are produced, including glass fibers, as well as fiber-shaped ceramics whose main ingredients are alumina, silica, titanine, magnesia, calcium oxide, etc. In either case, the fiber length is 5 to 20 mm or less. However, the physical conditions required for the catalyst support are
It must be able to constantly and stably contact a gas flow with a constant flow rate of 1 to 5 m/sec and not cause pressure loss. Therefore, this diameter is 1 to 3 microns and the length is 5 to 3 microns.
The biggest problem is how to form short, fine fibers of 20 mm or less into a stable shape that meets the requirements for a catalyst carrier.

In the figure, A is a glass melting part, B is a spinning part, and C is a short fiber made of a heat-resistant adhesive and a heat-resistant material. The part where you spray the mixture with,
D indicates a drying oven. [This figure 1 is the same as the conventional apparatus for producing glass fibers, but the only difference is that in the conventional apparatus, the part C is the part where the sizing agent (surface treatment agent) is sprayed, whereas in the present invention, This C part is simply changed to a part to which a mixture of heat-resistant adhesive and short fibers made of heat-resistant material is sprayed. ] Glass fibers having a diameter of 9 microns are spun using the apparatus shown in FIG. 1 in a self-evident manner.

The thick thread acts as a spacer, reducing pressure loss and preventing drift. The surface of the thus obtained reticulated cloth is coated with a catalyst component. This is 500 parts of a 20 mol% chromic acid aqueous solution (weight ratio, same below)
500 parts of a 20 mol% nickel acetate aqueous solution was mixed with the mixture, followed by 250 parts of propylene glycol, and an esterification reaction was carried out for 1 hour to obtain a stable ester intermediate. 1,350 parts of a solution prepared by adding 100 parts of a 0.1 mol% palladium chloride aqueous solution to 1,250 parts of this intermediate were dip-coated onto 2,700 parts of the reticulated cloth, and the mixture was coated at 200°C for 10 minutes.
After drying for 1 hour, ester decomposition is completed by baking at 600℃ for 1 hour, and an active metal oxide catalyst is adhered to the surface of the short fiber carrier in the form of a film with a thickness of 0.1 to 0.2 microns. Activation treatment is performed at 600°C for 1 hour in a gas atmosphere.
