Abstract

<P>PROBLEM TO BE SOLVED: To provide an artificial decomposition method of a large amount of carbon dioxide. <P>SOLUTION: In this method, magnesium is burned to decompose carbon dioxide by filling the environment with only carbon dioxide, using the nature of magnesium that magnesium burns by robbing of oxygen from a substance having a firm covalent bond when no oxygen is present in the environment, which is a characteristic of magnesium that cannot be seen in other elements. This method is applicable to decomposing of carbon monoxide. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

この発明は、炭酸ガスを人工的に分解する方法に関する。  The present invention relates to a method for artificially decomposing carbon dioxide gas.

今まで、炭酸ガスは、植物による炭素同化作用といわれる自然がおこなってくれている方法でしか分解できなかつた。
現在問題となっている炭酸ガスの影響をみれば、それが証明されているといえる。
炭酸ガスの堅固な共有結合により、人工的なすべての方法が分解に成功しなかつたからである。Until now, carbon dioxide could only be decomposed in a way that nature is said to be called carbon assimilation by plants.
If we look at the influence of carbon dioxide, which is currently a problem, it can be said that it has been proved.
This is because all the artificial methods were not successfully decomposed due to the strong covalent bond of carbon dioxide.

しかしながら、以上の技術によれば、植物に頼るしか方法はなく、人工的に大量に分解するなぞとゆう事は、出来なかった。
そこで、この発明は，人工的方法でしかも大量に炭酸ガスを分解する方法を提供することを課題とする。However, according to the above technique, there is no other way but to rely on plants, and it has not been possible to artificially decompose in large quantities.
Accordingly, an object of the present invention is to provide a method for decomposing carbon dioxide in a large amount by an artificial method.

以上の課題を解決するために、第一発明は、金属マグネシュウムの、他に類のない特性を利用することを特徴とする、炭酸ガスの人工的分解方法である。In order to solve the above-mentioned problems, the first invention is an artificial decomposition method for carbon dioxide characterized by utilizing a unique characteristic of metal magnesium.

マグネシウムは、発火すると劇しく燃焼するが、周囲に酸素が無い場合は、他の竪固な結合をした物質からでも、その酸素を奪ってでも燃焼する特性を持つ元素である。
これを利用し、周囲を炭酸ガスで満たし酸素が無い状態にし内部でマグネシュウムを燃焼させると、その結合酸素を奪って燃焼し続け、炭酸ガスが無くなるまでそれを持続させる。
これは、よく知られた反応で、目新しいことではなく、ただ炭酸ガスの分解方法としては、考え付かなかっただけで、周知の確認されている反応である。
そして、どのようになるかは，下記の良く知られた反応式となる。

Figure 2007289908
この反応式より炭酸ガスは、酸化マグネシウムと炭素となり、分解される事をしめす。
分解される量は、炭酸ガスの分子量が４４、２Ｍｇが２４だから、炭酸ガス４４グラムを分解するのには、２４グラムのマグネシウムが必要となる事をもしめす。
炭酸ガスの容量は、標準状態の体積で、４４グラムで２２・４リットルとされており、２４グラムのマグネシウムで、２２・４リットルの純炭酸ガスが分解できる事が判る。
なお、炭酸ガスは、マグネシウムの反応時間の関係で気体が効率よく、例えばドライアイスの様な運搬しやすく、気化が楽に行える形態が、反応時間も短く、分解と気化が繰り返し行う事が出きるので、時間的にも有利である。
マグネシウムの量は、地球の元素のなかで、８番目に多いとされており、リサイクル性にすぐれ、リサイクルシステムの整備も、他の金属より簡単で，新材製造時の５パアセント程度のコストで、リサイクルできるとされている。（下記文献資料より）
ＯＳＡＫＡ ＦＵＪＩ Ｃｏｒｐｏｒａｔｉｏｎ マグネシウムの特性 ｈｔｔｐ／／ｗｗｗ．ｏｆｉｃ．ｊｐ／ｍｇ／ｍａｇｎｅ．ｈｔｍ Ｗｅｂ版ＣＭＣＲｐｏｒｔ注目技術・市場動向。マグネシウム合金の市場。 ｈｔｔｐ／／ｗｗｗ．ｃｍｃｂｏｏｋｓ．ｃｏ．ｊｐ／ｒｅｅｗ／ｒｅｖｉｅｗ０１＝０７．ｈｔｍｌ Magnesium burns dramatically when ignited, but when there is no oxygen in the surroundings, it is an element that has the property of burning even if it is deprived of oxygen even from other solidly bonded substances.
When this is utilized and the surroundings are filled with carbon dioxide gas and oxygen is burned, the magnesium is burned inside, and the combined oxygen is deprived and burned, and it is maintained until the carbon dioxide gas runs out.
This is a well-known reaction, not a novel one, and it is a well-known and confirmed reaction just as a method for decomposing carbon dioxide gas.
And what happens is the following well-known reaction formula.
Figure 2007289908
 From this reaction formula, carbon dioxide gas is converted into magnesium oxide and carbon, indicating that it is decomposed.
The amount to be decomposed is that the molecular weight of carbon dioxide gas is 44, and 2Mg is 24. Therefore, it is suggested that 24 grams of magnesium is required to decompose 44 grams of carbon dioxide gas.
The capacity of the carbon dioxide gas is a standard volume of 44 grams, 22.4 liters, and it can be seen that 24 grams of magnesium can decompose 22.4 liters of pure carbon dioxide gas.
Carbon dioxide gas is efficient due to the reaction time of magnesium. For example, it can be easily transported and vaporized easily like dry ice, but the reaction time is short and decomposition and vaporization can be repeated. Therefore, it is advantageous in terms of time.
Magnesium is the 8th most abundant element of the earth, and is excellent in recyclability, and the maintenance of the recycling system is easier than other metals, and costs about 5 percent when manufacturing new materials. It can be recycled. (From the following document)

この発明の一実施形態を、１図にしめす。
耐熱性のある容器１の底に、燃焼しやすいリボン状のマグネシウム３を置き容器１を炭酸ガスの気体で満たす。
ロウソクの火で、上部まで満たされたことを確認した後、マグネシウム３に、点火した後、蓋２を容器１の上にのせ，密閉する。An embodiment of the present invention is shown in FIG.
A ribbon-like magnesium 3 that is easy to burn is placed on the bottom of the heat-resistant container 1 and the container 1 is filled with a carbon dioxide gas.
After confirming that the upper part is filled with a candle, after igniting the magnesium 3, the lid 2 is placed on the container 1 and sealed.

実施形態の効果Effects of the embodiment

この実施形態によれば、マグネシウムが、燃焼した後に蓋２を取り、容器１の中にロウソクの火をいれて消火しなければ、炭酸ガスが全量分解されたことになる。
炭酸ガスのなかでは、火は消えると言う特性を利用したもので、反応後容器１のなかに、炭酸ガスが分解されず残っていれば、その位置まで火が達すると必ず消える。
炭酸ガスは空気より重く、容器１の底に溜まるので外部からの酸素を絶つ為の蓋２は、必ずしも必要ではなく酸素は入り込めないが、より正確を期すためである。
仮に、容器１の容量が２リットルだとすれば、マグネシウムの量は、前述の化学式［化１］より全量分解するには、約３グラムあれば良いことが判る。According to this embodiment, if the lid 2 is removed after the magnesium is burned and a candle is put in the container 1 to extinguish it, the carbon dioxide is completely decomposed.
In the carbon dioxide gas, the characteristic is that the fire is extinguished. If the carbon dioxide gas remains in the container 1 after the reaction without being decomposed, it always goes out when the fire reaches that position.
Since carbon dioxide gas is heavier than air and accumulates at the bottom of the container 1, the lid 2 for cutting off oxygen from the outside is not always necessary and oxygen cannot enter, but it is for accuracy.
If the capacity of the container 1 is 2 liters, it can be seen that the amount of magnesium is about 3 grams in order to decompose the whole amount from the above chemical formula [Chemical Formula 1].

他の実施形態Other embodiments

図１の実施形態では、炭酸ガスの分解効果を確認する為の小規模実施例だが、他の実施形態では、大規模に分解する場合でも、まったく同様に、その規模のみ大きくすればよく、耐熱性のある上部に開閉できるシステムをもつ密閉できる部屋または空間をつくり、その底辺部分に連続してマグネシウムを供給できる様にし、マグネシウムを発火させる装置を設備すれば、部屋または空間に応じた量の炭酸ガスが分解できる。
分解する炭酸ガスの、約半分強の重量のマグネシウムが必要なので、２トンの炭酸ガスの分解には、約１トン強のマグネシウムを用意すればよく、その規模に応じた容量と耐熱性と、外部酸素を遮断さえ出来れば、他の設備し易い方式のものでも良い。In the embodiment of FIG. 1, although it is a small-scale example for confirming the decomposition effect of carbon dioxide gas, in other embodiments, even when decomposing on a large scale, it is just necessary to enlarge only the scale, If you create a sealed room or space with a system that can be opened and closed at the top, make it possible to supply magnesium continuously to the bottom of the room, and install a device that ignites magnesium, the amount corresponding to the room or space Carbon dioxide can be decomposed.
Since about half the weight of magnesium to decompose carbon dioxide is required, it is sufficient to prepare about 1 ton of magnesium for decomposition of 2 tons of carbon dioxide, and capacity and heat resistance according to the scale, As long as the external oxygen can be shut off, other types of systems that are easy to install may be used.
