公報、特公昭５９−４００６２号公報）。2. Prior Art A conventional catalyst body of this type consists of a catalyst 2 and a binder 3 on the surface of a metal porous body 1, as shown in FIG. The method was to apply a 100% polyester resin and bake it, and to decompose the adhering fats and oils 4 at about 300°C (for example, Japanese Patent Publications No. 7539/1983 and Japanese Patent Publication No. 40062/1982).

よりはっきりする。Problems to be Solved by the Invention However, in the above structure, there was a problem in that the catalyst was hidden in the coating due to the binder, and high oxidation ability could not be obtained. This is more clearly evaluated based on the appearance of the surface of the catalyst after decomposition treatment, rather than based on the weight loss of fats and oils.
従来、重量減少が大きいとされているものでも、外観は
油脂類の跡が明らかに残っていた。Even products that were traditionally considered to have a large weight loss still had visible traces of oil and fat on their exteriors.

ができる。Effect: By the means described above, the air permeability of the catalyst body is improved, and when the fat and oil is oxidized and decomposed, oxygen is sufficiently supplied, and the SiO. ,AI
! O. When oils and fats adhere to the porous coating selected from among these, the wettability improves, so that they are in uniform contact without being concentrated locally, and they also come into direct contact with the oxidation catalyst, resulting in high activity. This results in the oxidative decomposition of EXAMPLES Hereinafter, examples of the present invention will be explained based on the attached drawings. FIG. 1 is an enlarged sectional view of the catalyst body of the present invention, in which a Sin. After forming a porous film 6 mainly composed of Mn by anodizing method,
, Fe, Co, NiCu, Ce. The catalyst 7 was supported in an exposed state by immersing it in a solution such as acetate or by spraying the solution, then drying and baking at 45°C for 30 minutes. The oils and fats 4 adhering to the surface of the catalyst form a porous film 6 containing Sing as its main ingredient.
Because of its good wettability, it contacts uniformly without being concentrated locally, and also directly contacts the exposed catalyst 7. Aluminum fibers 8 supporting the catalyst 7 as described above are intertwined to form air vents 9 as shown in FIG. In order to improve the mechanical strength and maintain the shape, the oil and fat oxidation catalyst body as shown in FIG. 5 is produced by processing it into a sandwich shape with aluminum expanded lO as shown in FIG. 4 from the top and bottom.

in. A catalyst may be supported after forming a porous coating mainly composed of . The following table shows the oxidative decomposition characteristics of oils and fats by the catalyst produced by the above method in comparison with conventional examples.

用いるとよい。(Left below) As can be seen from the table above, the decomposition performance is low when a binder is used or when ordinary aluminum temporary rather than fibrous material is used. In other words, it is affected by the diffusion of oxygen (air). As for the supported catalyst, it is preferable to use one or more of Mn, Fe, Co, Ni, and Cu+Ce.

った。Performance evaluation of fat and oil decomposition was carried out by dropping a fixed amount of salad oil onto a 10 cm x 10 cm (approximately 1 cm thick) catalyst body using a dropper. As a result, as shown in the table, in the examples of the present invention, there were no traces and the weight reduction of salad oil was 100%.

持されていることによると考えられる。On the other hand, in the present invention, since the catalyst is directly supported, there was a concern that the catalyst would peel off, but when a peeling test was performed using a tape on the catalyst body of the example, peeling was observed at the edge of the expanded metal. However, other than that, they showed strong adhesion. This is thought to be due to the fact that the Sing coating and the aluminum fibers are strongly electrochemically bonded, and the Si02 coating is extremely porous, so that the supported catalyst is retained within the pores.

られた。In this example, an example in which Sing was used as the main component of the porous coating was described, but similar results were obtained with a catalyst body in which a porous coating was formed with A1203 as the main component.

The laminated structure of aluminum fibers improves air permeability and provides a sufficient supply of oxygen when oils and fats are oxidized and decomposed.
．． Alternatively, when oils and fats adhere to a porous film containing AI20 as its main component, it has good wettability, so it contacts uniformly without concentrating locally, and it also comes into direct contact with the oxidation catalyst, resulting in high activity. % oils and fats can be oxidized and decomposed.
