【発明の詳細な説明】 〔産業上の利用分野〕 本発明は助燃剤および酸素含有ガスを用いてフロンまた
はフロン含有物を燃焼させ、分解する方法に関する。Description: TECHNICAL FIELD The present invention relates to a method for burning and decomposing CFCs or CFC-containing materials using a combustion improver and an oxygen-containing gas.
フロンは極めて安定な化合物であり、しかも無害で多く
の有用な性質を有するため、これまでスプレー剤、発泡
剤、冷媒等として多量に使用されてきた。しかしなが
ら、これを破壊処理する技術はこれまで知られていなか
った。Freon is an extremely stable compound, and since it is harmless and has many useful properties, it has been used in large amounts as a spray agent, a foaming agent, a refrigerant, and the like. However, the technology of destroying this has not been known so far.
最近に至り、オゾン層破壊問題に見られる地球環境問題
がクローズアップされるようになったが、フロンを積極
的に分解する技術は従来全く確立されていない。Recently, the problem of global environment seen in the ozone layer depletion problem has come to the fore, but the technology to actively decompose CFCs has not been established at all.
一般に有害廃棄物の破壊処理方法として焼却法がある
が、フロンは難分解性のため通常の焼却法では全く分解
されないとされている。Generally, there is an incineration method as a method for destroying hazardous wastes, but it is said that CFCs are not decomposed at all by a normal incineration method because they are difficult to decompose.
そこで本発明は、フロンを分解し無害化するための効率
的な方法を提供することを目的とするものである。Therefore, an object of the present invention is to provide an efficient method for decomposing and detoxifying freon.
上記目的を達成するための本発明のフロンの分解方法
は、水素または炭素水素系を助燃剤、酸素含有ガスおよ
びフロンまたはフロン含有物からなる混合物に点火燃焼
させることを特徴とするものである。The method for decomposing chlorofluorocarbon of the present invention to achieve the above object is characterized by igniting and burning a hydrogen or carbon-hydrogen system into a mixture of a combustion improver, an oxygen-containing gas and chlorofluorocarbon or a fluorocarbon-containing substance.
酸素含有ガスとしては、空気、酸素富化空気または酸素
が用いられ、燃焼は常圧または加圧下で行われ、点火は
フロンまたはフロン含有物を助燃剤および酸素含有ガス
と混合し、この混合物に耐圧密閉容器中で点火すること
に寄り行われる。フロンは不燃性である。As the oxygen-containing gas, air, oxygen-enriched air or oxygen is used, combustion is carried out at normal pressure or under pressure, ignition is performed by mixing CFCs or CFC-containing substances with a combustion improver and an oxygen-containing gas, and adding to the mixture. It is carried out by igniting in a pressure tight container. Freon is nonflammable.
事実、フロンと酸素とは例え反応したとしても吸熱反応
である。例えば、フロン−12と酸素の直接的反応は吸熱
反応であり、熱力学的にも無理がある。In fact, Freon and oxygen are endothermic reactions even if they react. For example, the direct reaction between Freon-12 and oxygen is an endothermic reaction, which is thermodynamically impossible.
しかしながら、熱力学的には、燃料、すなわち助燃剤、
例えばメタンが存在すれば下記（１）のように反応し、
この反応は229.9Kcal/molの発熱反応となる。However, thermodynamically, the fuel, i.e. the combustion improver,
For example, if methane is present, it will react as in (1) below,
This reaction is an exothermic reaction of 229.9 Kcal / mol.
CCl2F2＋2O2＋CH4＝2CO2＋2HCl＋2HF （１） この反応では、左辺のどの化学結合も反応によって、よ
り強い結合に変化する。CCl 2 F 2 ＋ 2O 2 ＋ CH 4 ＝ 2CO 2 ＋ 2HCl ＋ 2HF (1) In this reaction, any chemical bond on the left side is changed into stronger bond by the reaction.
すなわち、Cl原子においては、Cl-CからCl-Hへ、Ｆ原子
においてはF-CからF-Hへ、そしてＣ原子においてはC-F
またはC-ClからCO2中のＣ＝Ｏへと変化しているが、こ
れらはいづれもより強い結合への変化になっている。That is, Cl-C to Cl-H for Cl atoms, FC to FH for F atoms, and CF for C atoms.
Or has been changed to C = O in CO 2 from the C-Cl, it has become change to a stronger binding also Izure.
他のＯ原子、Ｈ原子に関しても同様である。The same applies to other O atoms and H atoms.
従って、（１）式の化学反応は無理なく自然に進行する
反応である。助燃剤が十分に存在すれば、反応の活性化
エネルギーは燃焼熱でまかなわれることになり、反応は
自動的に進行し、熱化学的に燃焼法は極めて有効な方法
である。Therefore, the chemical reaction of the formula (1) is a reaction that naturally proceeds naturally. If a sufficient amount of the combustion improver is present, the activation energy of the reaction will be covered by the heat of combustion, the reaction will proceed automatically, and the thermochemical combustion method is an extremely effective method.
この燃焼法を上記フロン−12を例に熱力学的観点から、
熱分解法、酸化法、還元法、加水分解法、微生物分解法
と比較してみると下記のようになる。From the thermodynamic point of view of the above Freon-12 combustion method,
The comparison with the thermal decomposition method, oxidation method, reduction method, hydrolysis method, and microbial decomposition method is as follows.
熱分解法： CCl2F2→Ｃ＋Cl2＋F2 ΔＨ＝＋114.0Kcal/mol 酸化法： CCl2F2＋O2→CO2＋Cl2＋F2 ΔＨ＝＋19.9Kcal/mol 還元法： CCl2F2＋4H2→CH4＋2HF＋2HCl ΔＨ＝−77.7Kcal/mol 加水分解法： CCl2F2＋2H2O→CO2＋2HCl＋2HF ΔＨ＝−38.3Kcal/mol 微生物法： 加水分解法と同じと考えられる。Pyrolysis method: CCl 2 F 2 → C + Cl 2 + F 2 ΔH = ＋ 114.0Kcal / mol Oxidation method: CCl 2 F 2 ＋ O 2 → CO 2 ＋ Cl 2 ＋ F 2 ΔH ＝ + 19.9Kcal / mol Reduction method: CCl 2 F 2 + 4H 2 → CH 4 + 2HF + 2HCl ΔH = −77.7 Kcal / mol Hydrolysis method: CCl 2 F 2 + 2H 2 O → CO 2 + 2HCl + 2HF ΔH = −38.3 Kcal / mol Microbial method: It is considered to be the same as the hydrolysis method.
燃焼法： 上記（２）式の反応 ΔＨ＝−153.9Kcal/mol これらの化学式から明らかなとおり、熱分解法や酸化法
ではそもそも反応が起こらない。Combustion method: Reaction of the above formula (2) ΔH = −153.9Kcal / mol As is clear from these chemical formulas, no reaction occurs in the first place by the thermal decomposition method or the oxidation method.
還元法や加水分解法は原理的には実行可能であるが、反
応の相手は水素や水であるから外部から相当加熱しない
と反応は進行しない。Although the reduction method and the hydrolysis method can be carried out in principle, the reaction partner is hydrogen or water, so the reaction does not proceed unless it is considerably heated from the outside.
しかし、燃焼法では、燃料と酸素の反応熱を直接内部で
利用する形で反応が進むので、熱化学的に有効であり、
外部からの加熱も必要としない。However, in the combustion method, the reaction proceeds by directly utilizing the heat of reaction between the fuel and oxygen inside, so it is thermochemically effective,
No external heating is required.
そこで本発明においては、燃料、すなわち助燃剤を使用
する。Therefore, in the present invention, a fuel, that is, a combustion improver is used.
助燃剤としては、水素または炭化水素系の燃料、例えば
メタン、天然ガス、プロパン、重油等が用いられる。Hydrogen or hydrocarbon fuels such as methane, natural gas, propane, and heavy oil are used as the combustion improver.
また、燃焼に際しては、酸素含有ガス、例えば空気、酸
素富化空気または酸素が用いられ、反応を促進するため
には、反応系を加圧状態にするか、空気よりも酸素濃度
の高い酸素富化空気または酸素を供給するか、またはこ
れら両者の併用が好ましい。In addition, an oxygen-containing gas such as air, oxygen-enriched air, or oxygen is used in the combustion. It is preferable to supply modified air or oxygen, or to use a combination of both.
本発明において処理対象となるフロンとしては、上記に
例として挙げたCCl2F2（フロン−12）の他にCCl3F（フ

燃焼容器としては、バーナー等を用いた開放容器を使用
することもできるが、フロンが通常ガス状であり、助燃
剤、酸素含有ガスもガス状であるので密閉容器が好都合
であり、容器にフロン、助燃剤、酸素含有ガスを供給し
た後に十分に撹拌することが好ましい。As the combustion container, an open container using a burner or the like can be used, but since the chlorofluorocarbon is usually in a gaseous state and the combustion improver and the oxygen-containing gas are also in a gaseous state, a closed container is convenient, and a chlorofluorocarbon container is used. It is preferable to sufficiently stir after supplying the combustion improver and the oxygen-containing gas.
点火は例えば火花放電またはニクロム線への通電によっ
て行う。Ignition is performed by, for example, spark discharge or energization of a nichrome wire.

燃焼は常温、常圧で行うことができるが、上記のように
反応をより速やかに進行させるためには、耐圧密閉容器
中で５〜10気圧に加圧したり、また酸素含有ガスによる
酸素濃度の上昇をはかることが好ましい。Combustion can be carried out at room temperature and atmospheric pressure, but in order to make the reaction proceed more quickly as described above, pressurization to 5 to 10 atm in a pressure-resistant closed container, and oxygen concentration by oxygen-containing gas It is preferable to increase.
