料−空気混合を完全にするよう、芯の着火部に多
くの空間をもたせた構造が最近多くなつている。 Up to now, glass fibers and the like have been used for the wicks of alcohol lamps and commercially available petroleum (kerosene burning) stoves. The lamp uses this wick to suck up liquid fuel and burn it at the top, which is the principle of a kerosene heating stove.
It is clear that the structure of these wicks is related to combustion efficiency, and various forms of wicks have been devised, including structures with more space in the ignition part of the wick to achieve more complete fuel-air mixing. Recently, it has become more common.
しかし、特に石油ストーブ用の芯の場合、未だ
解決されていない問題点として、次の点が考えら

著しく、部屋の中に、悪臭を充満させる。(1) Due to incomplete oxidation during combustion, it is not oxidized to CO 2 and H 2 O, so oxidized hydrocarbons are generated in various parts, causing bad odors (especially aldehydes, etc.). This phenomenon is particularly noticeable during ignition and extinguishing, and fills the room with a foul odor.

ので、以下実施例をもつてその構成を詳述する。 The present inventors focused on the above points and improved the material of the combustion wick to significantly improve these problems, and as a result, they invented an efficient combustion wick, and the following examples are provided. The structure will be explained in detail.

維、２は白金粒子である。Example 1 After forming long glass fibers with a diameter of 5 μm into a mat shape, immersing them in concentrated sulfuric acid for about 1 day reduces the BET surface area.
The alkali component in the glass fiber was removed, and the silica (SiO 2 ) purity was 92%. This was immersed in a chloroplatinic acid solution and heated to 120% over 2 hours.
It was dried at 600°C for 3 hours. The combustion wick thus prepared had 0.4wt% of platinum attached to the glass mat. This was used as a combustion wick.
An enlarged view is shown in FIG. 1, where 1 is a glass fiber and 2 is a platinum particle.

とした。Example 2 After forming long glass fibers with a diameter of 3 μm into a pine shape, the glass fibers were dealkalized with a strong acid etc. to have a surface area of 80 m 2 /g or more, and silica sol (3 wt% SiO 2 ) was applied to the surface of the glass fibers. After drying at 120°C, it was fired at 550°C. On the other hand, a slurry was prepared in which alumina and cobalt nitrate were well dispersed in water. To the glass matte made as described above,
This slurry was applied, dried at 120°C for 2 hours, and fired at 550°C for 3 hours. The alumina-cobalt oxide layer thus created was further formed on the base mat in an amount of 21 wt% of its weight. Further, the mixing ratio of this layer was Al/CO1.2 (atomic ratio). The product thus created was used as a combustion wick.

平均全炭化水素を連続測定した。 Next, the combustion wick prepared in Example 1 and a conventional commercially available glass fiber wick were actually applied to a kerosene stove. Ignition → combustion → in the same stove
We conducted an experiment using a cycle of extinguishing fires, and continuously measured the average total hydrocarbons released during the extinguishing cycle.
この結果、第３図に示すように、大気中に放出

のである。 As a result, as shown in Figure 3, the total hydrocarbons emitted into the atmosphere are lower in the case of the kerosene stove using the wick of Example 1 than in the case of the kerosene stove using the conventional wick. The amount of hydrogen had decreased to 1/2 to 1/3. Further, in the conventional example, the concentration increases with time of use, but in the first embodiment of the present invention, this increase in the total discharged hydrocarbon concentration is suppressed. Thus, when using the wick of the present invention, the total hydrocarbon concentration released into the atmosphere is reduced, resulting in a significant reduction in odor, and the initial effect is maintained even during long-term durable use. I was able to maintain it.
Additionally, these increases in combustion efficiency mean more effective use of fuel, and especially when used for heating, it also has an energy saving effect.

を向上させることができる。 As described above, in the present invention, glass fibers are dealkalized with a strong acid or the like to have a surface area of 80 m 2 /g or more. It is a combustion wick to which at least one metal oxide of a transition metal such as cobalt oxide is attached, and its major feature is that a so-called supported catalyst is used as a combustion wick for a liquid fuel combustor. Combustion efficiency can be improved.

る。 In addition, compared to the conventional glass fiber pine core,
Due to the dealkalization treatment, the fiber surface has many micropores, which further improves its function as a core for sucking up liquid fuel. As a result, contact with the catalyst during the fuel vaporization stage is carried out efficiently, and the combustion reaction of the malodorous components and unburned hydrocarbons by the catalyst proceeds more reliably, increasing the conversion and removal efficiency of these components. It can be greatly improved.
ここで、脱アルカリ処理後のガラス繊維の表面
積は50m2/ｇ以上、好ましくは80m2/ｇ以上となる
ように処理を行なうことが必要である。 Here, it is necessary to perform the treatment so that the surface area of the glass fiber after the dealkalization treatment is 50 m 2 /g or more, preferably 80 m 2 /g or more.

It is not affected by its shape, etc., and may be any other high-temperature stable inorganic material. Further, the metal to be deposited may be a noble metal other than platinum, such as palladium, rhodium, iridium, silver, etc., and the metal oxide of a transition metal may be nickel oxide, copper oxide, manganese oxide, etc. in addition to cobalt oxide. good.
