The present invention relates to a reaction vessel used in the production method.
地球温暖化現象は、種々の要因によって引き起こされている現象であるが、人間の産業活動に伴って大気中に排出された炭酸ガス（ＣＯ２）などの温室効果ガスが大きな要因となっているとする説が主流となっている。そのため、炭酸ガスの排出量の削減が国際的な課題とされている。又、排出された炭酸ガスを回収する手段についても開発が進められている。 Global warming is a phenomenon caused by various factors, but greenhouse gases such as carbon dioxide (CO 2 ) discharged into the atmosphere with human industrial activities are a major factor. The theory is becoming mainstream. Therefore, reducing carbon dioxide emissions is an international issue. Development of means for collecting the discharged carbon dioxide gas is also in progress.
炭酸ガスを回収する手段としては、大気中の二酸化炭素を吸着し、吸着した二酸化炭素を光分解する吸着分解触媒が開発されている（例えば、下記特許文献１参照）。 As means for recovering carbon dioxide gas, an adsorptive decomposition catalyst that adsorbs carbon dioxide in the atmosphere and photodecomposes the adsorbed carbon dioxide has been developed (for example, see Patent Document 1 below).
しかしながら、光分解による二酸化炭素の分解は、紫外線領域の光エネルギーが必要であり、夜間や暗所では、効率よく二酸化炭素を分解することができない。 However, decomposition of carbon dioxide by photolysis requires light energy in the ultraviolet region, and carbon dioxide cannot be efficiently decomposed at night or in dark places.

［実施例１］
錫６０重量部と、鉛４０重量部とからなる錫合金１００重量部に対し、粉末状の窒化アルミニウム（粒径１〜１．５μｍ）５重量部を加えて原料を調整した。この原料を、図１（ａ）に示す鉄製の容器（縦７００ｍｍ×横５００ｍｍ×深さ５０ｍｍ）２に収容したうえで、前記容器２の上部開口を鉄製の蓋３にて覆った。
[Example 1]
A raw material was prepared by adding 5 parts by weight of powdered aluminum nitride (particle size: 1 to 1.5 μm) to 100 parts by weight of a tin alloy composed of 60 parts by weight of tin and 40 parts by weight of lead. The raw material was accommodated in an iron container (length 700 mm × width 500 mm × depth 50 mm) 2 shown in FIG. 1A, and the upper opening of the

［比較例１］
前記実施例１と同様の原料を前記容器２内に収容し、前記容器２の上部開口を前記蓋３にて覆ったうえで、磁場に晒すことなく焼成（４００℃、３０分）を行うことによって、比較例１に係る担体を得た。
[Comparative Example 1]

＜本発明方法（炭酸ガスの接触分解）＞
実施例１、実施例２にて得られた本発明担体、及び比較例１、比較例２にて得られた担体を下記に示す手順からなる接触分解試験に供した。
<Method of the present invention (catalytic decomposition of carbon dioxide gas)>
The carrier of the present invention obtained in Example 1 and Example 2, and the carrier obtained in Comparative Example 1 and Comparative Example 2 were subjected to a catalytic decomposition test comprising the following procedure.
‐試験‐
（１）各担体を破砕し、２〜３ｃｍ角程度の破砕物とする。
（２）容量５リットルのテトラバッグを用意し、各担体の粉砕物２００ｇを各々前記テトラバッグに入れる。
（３）各テトラバッグ内に、３リットルずつ炭酸ガス（二酸化炭素濃度：９９．５％）を注入する。
（４）炭酸ガスの注入後、各テトラバックを室内（２５℃）に静置し、定期的に各テトラバッグ内の二酸化炭素濃度をガス検知管にて測定する。
係る接触分解試験の結果を下記表１に示す。
-test-
(1) Each carrier is crushed into a crushed material of about 2 to 3 cm square.
(2) A tetra-bag having a capacity of 5 liters is prepared, and 200 g of each carrier pulverized product is put into the tetra-bag.
(3) Carbon dioxide (carbon dioxide concentration: 99.5%) is injected into each tetra bag by 3 liters.
(4) After injecting carbon dioxide, each tetrabag is left in the room (25 ° C.), and the carbon dioxide concentration in each tetrabag is periodically measured with a gas detector tube.
The results of the catalytic cracking test are shown in Table 1 below.
表１に示す結果より、実施例１、実施例２にて得られた本発明担体は、試験開始後７２時間以内で、テトラバック内に注入された３リットルの炭酸ガスを全て処理した。これより、本発明担体における、炭酸ガスに対する良好な接触分解能を確認することができた。 From the results shown in Table 1, the carrier of the present invention obtained in Example 1 and Example 2 treated all 3 liters of carbon dioxide injected into the tetrabag within 72 hours after the start of the test. From this, it was possible to confirm good contact resolution with respect to carbon dioxide gas in the carrier of the present invention.
又、実施例１にて得られた本発明担体と比較して、実施例２にて得られた本発明担体の方が二酸化炭素に対する接触分解スピードが高いことが確認された。これは、原料を調整する際に、窒化アルミニウムをアルカリ溶液に分散させたことにより、空気中の水分によって窒化アルミニウムが分解される反応が抑制されたことを原因とすると考えられる。 In addition, it was confirmed that the carrier of the present invention obtained in Example 2 has a higher catalytic decomposition speed for carbon dioxide than the carrier of the present invention obtained in Example 1. This is considered to be caused by the fact that aluminum nitride is dispersed in an alkaline solution when the raw material is prepared, thereby suppressing the reaction of aluminum nitride being decomposed by moisture in the air.
一方、焼成工程時において磁場に晒すことなく焼成された比較例１に係る担体や、窒化物が配合されていない比較例２に係る担体は、炭酸ガスに対する接触分解能を有していないことが認められた。 On the other hand, the carrier according to Comparative Example 1 that was fired without being exposed to a magnetic field during the firing step or the carrier according to Comparative Example 2 that was not compounded with nitride did not have a contact resolution for carbon dioxide gas. It was.
次いで、実施例１、及び実施例２に係る本発明担体につき、テトラバック内の二酸化炭素濃度が０％となった時点で、テトラバック内に３リットルの炭酸ガスを再度注入する作業を繰り返すことによって、本発明担体一重量単位当たりの二酸化炭素分解量を検討したところ、実施例１に係る本発明担体は、一重量単位当たり、重量にして１００倍以上の二酸化炭素を分解し得ることが確認された。又、実施例２に係る本発明担体は、一重量単位当たり、重量にして１５０倍以上の二酸化炭素を分解し得ることが確認された。 Next, for the carrier of the present invention according to Example 1 and Example 2, when the carbon dioxide concentration in the tetrabac becomes 0%, the operation of injecting 3 liters of carbon dioxide gas again into the tetrabac is repeated. The amount of carbon dioxide decomposition per unit of weight of the carrier of the present invention was examined by the above, and it was confirmed that the carrier of the present invention according to Example 1 can decompose carbon dioxide 100 times or more by weight per unit of weight. It was done. Further, it was confirmed that the carrier of the present invention according to Example 2 can decompose 150 times or more of carbon dioxide by weight per weight unit.
又、炭酸ガスに替えて、テトラバック内にアンモニアガスを注入して同様の試験を行ったところ、本発明担体は、アンモニアガスに対する接触分解能も有することが確認された。 In addition, when a similar test was performed by injecting ammonia gas into the tetrabag instead of carbon dioxide, it was confirmed that the carrier of the present invention also has a contact resolution for ammonia gas.
これより、本発明担体は、炭酸ガスのみならず、アンモニアガス等のその他の気体成分についても、良好な接触分解能を有することが認められた。 From this, it was confirmed that the carrier of the present invention has good contact resolution not only with carbon dioxide gas but also with other gas components such as ammonia gas.

It was confirmed that the above could be processed.

又、前記実施例１５においては、磁場を発生させる要素として電磁石を用いているが、焼成時において電磁石による磁場に晒した場合にあっても、二酸化炭素ガスに対する接触分解能が得られることが確認された。 In Example 15, an electromagnet is used as an element for generating a magnetic field, but it has been confirmed that contact resolution with carbon dioxide gas can be obtained even when exposed to a magnetic field generated by an electromagnet during firing. It was.
