やホスフィンの如き水素ガス等の強力な有毒ガスの他、
亜硫酸ガス、硫化水素等の有害汚染物質も、完全に除去
することが要請される。In the semiconductor industry, in addition to powerful toxic gases such as hydrogen gas such as arsine and phosphine, which are present at extremely low concentrations in the atmosphere,
Harmful pollutants such as sulfur dioxide gas and hydrogen sulfide are also required to be completely removed.
本発明は、このような低濃度のガスで環境汚染された空
気をランニングコストの低い効果的方法で清浄化するこ
とを目的として、課題の解決を図るものである。The present invention aims to solve the problem by purifying air contaminated with such low concentration gases by an effective method with low running costs.

かかる無機質担体に担持される過マンガン酸カルシウム
は担体の物性や汚染ガス状況によりその担持量を適宜設
定することができるが、前記のように、成型体全吊当り
２〜３０重量％、好ましくは３〜２０重量％の範囲にあ
る。The amount of calcium permanganate supported on such an inorganic carrier can be set as appropriate depending on the physical properties of the carrier and the contaminated gas situation, but as mentioned above, it is preferably 2 to 30% by weight per total hanging of the molded body. It is in the range of 3 to 20% by weight.
この理由は、約２重量％より少量にあって１よ、水素化
ガス等の除去効果が不充分であるか、使用ライフが短か
くなる傾向にあり、又約３０重量％を越えることは成型
体の比表面積や空孔容積を所望の範囲にできなくなり、
担持量に対応する除去効果が期待できないことによる。The reason for this is that if the amount is less than about 2% by weight, the removal effect of hydrogen gas etc. is insufficient or the service life tends to be shortened, and if it exceeds about 30% by weight, the molding It becomes impossible to maintain the specific surface area and pore volume of the body within the desired range,
This is because the removal effect corresponding to the supported amount cannot be expected.

It can be used as appropriate.
本発明は、かかる空気浄化剤に空間速度ＳＶ値を５００
０以下で低温度汚染空気と接触させることが重要である
。The present invention provides such an air purifying agent with a space velocity SV value of 500.
It is important to bring the air into contact with low-temperature contaminated air at temperatures below 0.
この理由は、ＳＶ値５０００を越えると、空気浄化剤の
使用ライフが著しく短かくなると共に、極低濃度の汚染
ガスの除去ができないことになる。The reason for this is that if the SV value exceeds 5000, the service life of the air purifying agent will be significantly shortened, and extremely low concentration pollutant gases cannot be removed.
従って、本発明では、Ｓｖ値５０００以下で行うことが
必要であるが、特にＳＶ値が１０００〜４０００の範囲
が好適である。Therefore, in the present invention, it is necessary to perform the process at an Sv value of 5000 or less, but an SV value in the range of 1000 to 4000 is particularly suitable.
なお、ここでＳＶ値は、当業者にａ＞いて周知の条件で
あるが、次式で示されるものである。Note that the SV value here is a condition well known to those skilled in the art, and is expressed by the following formula.
次に、本発明において、対象となる汚染空気は、汚染ガ

気浄化剤で予め、高いＳＶ値で処理するか又は他の除去
方法で低濃度まで処理しておくことが必要である。Therefore, if the air is contaminated to a level higher than this concentration, it should be treated in advance with a high SV value using the air purification agent or other air purification agent in this defense, or reduced to a low concentration using other removal methods. It is necessary to process it.
また、本発明において、汚染空気は、空気浄化剤で接触
処理するに当り、適度の９度を有していることが望まし
いことから、湿度が低い場合は調湿しておくことが必要
であり、多くの場合、相対湿度が１５％以上にあればよ
−・１゜この理由は、極低濃度の汚染ガスが、湿度が低
い場合には除去でき難くなる傾向となるからである。Furthermore, in the present invention, it is desirable that contaminated air has an appropriate temperature of 9 degrees when contacting it with an air purifying agent, so if the humidity is low, it is necessary to adjust the humidity. In most cases, the relative humidity should be at least 15% - 1°.The reason for this is that extremely low concentrations of pollutant gases tend to be difficult to remove when the humidity is low.
本発明において、除去できる汚染ガスは極めて広範囲で
