Abstract
Description
본 발명은 오존분해용 산화망간계 촉매 및 그 제조방법에 관한 것으로서 특히 산화망간의 입자가 미세하고 균일한 분포를 가지며 넓은 표면적을 가지는 오존분해용 산화망간계 촉매 및 그 제조방법에 관한 것이다.The present invention relates to a manganese oxide catalyst for ozone decomposition and a method for producing the same, and more particularly to a manganese oxide catalyst for ozone decomposition having a fine and uniform distribution of manganese oxide having a large surface area and a method for producing the same.
오존은 그 자체 강력한 살균력이 있어서, 살균작용, 유기물 분해작용, 악취제거작용, 탈색작용을 하므로 가정용이나 산업용으로 광범위하게 사용되고 있다. 그러나, 오존은 유익한 작용을 하는 반면에 강력한 산화력을 가지고 있기 때문에 사용되고 난 후 소량의 오존이라도 남아 있게 되면 그 잔류오존이 인체에 치명적인영향을 주게 된다.Ozone has its own strong sterilizing power, and is widely used for home and industrial use because it sterilizes, decomposes organic matter, removes odors, and discolors. However, ozone has a beneficial effect, but has a strong oxidizing power, so if a small amount of ozone remains after being used, the residual ozone has a fatal effect on the human body.
최근에는 각종 고전압 발생장치, 예를들면 건식 복사기 등이 널리 보급되어 있으며 이런 장치에서 발생하는 오존은 미량이라 하더라도 실내가 오염되고 환경위생상 무시할 수 없는 영향을 주게 된다.In recent years, various high-voltage generators, such as dry copiers, have been widely used, and even ozone generated from such a device is contaminated indoors and has a negligible effect on environmental hygiene.
잔류오존은 비릿한 냄새를 유발할 뿐만아니라 사람의 호흡기에 악영향을 주고 미량이라도 장시간 흡입하면 상당히 유해하므로 이러한 잔류오존은 반드시 분해 처리하여 환경규제치 이하로 낮추어야 한다.Residual ozone not only causes vivid odor, but also adversely affects the human respiratory tract, and it is extremely harmful if inhaled even for a long time.
지금까지의 잔류오존 분해처리방법으로는 가) 활성탄에 의한 방법, 나) 열분해에 의한 방법, 다) 오존 분해촉매에 의한 방법 등이 알려져 있으나, 그 중 오존 분해촉매에 의한 방법이 경제적이며 효율적인 방법으로 알려져 있다.Until now, residual ozone decomposition treatment methods are known as: a) activated carbon, b) pyrolysis, c) ozone decomposition catalyst, but among them, ozone decomposition catalyst is an economical and efficient method. Known as
오존분해촉매로서는 산화망간이 종래로부터 잘 알려져 있다.Manganese oxide is well known from the past as an ozone decomposition catalyst.
오존은 산화망간 촉매의 존재하에서 다음과 같은 반응을 하여 분해된다.Ozone is decomposed by the following reaction in the presence of a manganese oxide catalyst.
2O3+ MnO2-> 3O2+ MnO2------------ (1)2O 3 + MnO 2- > 3O 2 + MnO 2 ------------ (1)
산화망간계 오존분해촉매의 제조방법은 여러 가지가 알려져 있다. 이 경우 산화망간이 오존분해 촉매라고 한다면 그 촉매는 어떤 형상을 이루는 것이 실제 사용에 유리하므로 담체를 이용하게 되는데 담체의 표면에 촉매가 형성된 것을 촉매체라고 할 수 있다.Various methods for producing a manganese oxide ozone decomposition catalyst are known. In this case, if manganese oxide is an ozone decomposition catalyst, the catalyst may be formed in a certain shape, which is advantageous for practical use, and thus a carrier may be used. A catalyst is formed on the surface of the carrier.
예를들면 일본국 특허공개공보 소화63-197524호에는 질산망간 등의 망간 화합물의 용액을 침지하여 금속, 석면 및 세라믹 등의 무기담체 혹은 활성탄 등을 침지하여 그 후 가열처리하는 방법이 개시되어 있고, 일본국 특개소61-101230호에는 활성 이산화망간 또는 전해 이산화망간 등의 산화망간을 담체물질로 담지하는 방법이 개시되어 있으며, 국내 특허공보 등록번호 특1996-6926호에는 탄산망간을 함유하는 것을 특징으로 하는 촉매체에 대하여 기재되어 있다.For example, Japanese Patent Laid-Open No. 63-197524 discloses a method of immersing a solution of manganese compounds such as manganese nitrate, immersing inorganic carriers such as metal, asbestos and ceramics or activated carbon, and then heating the same. Japanese Patent Application Laid-Open No. 61-101230 discloses a method of supporting a manganese oxide such as active manganese dioxide or electrolytic manganese dioxide as a carrier material, and the Japanese Patent Publication No. 1996-6926 is characterized by containing manganese carbonate. It is described about the catalyst body.
또한 산화망간 이외에도 산화구리와 같은 금속의 산화물이 촉매로 이용될 수 있는데 그 제조방법으로는 금속의 질산염, 금속의 황산염 그리고 금속의 염화염 등을 알칼리 용액으로 중화시켜 침전물을 얻은 다음, 건조하고 소성하여 금속산화물을 얻은 다음, 이 금속산화물을 바인더와 함께 성형하여 최종적으로 오존분해 촉매체를 만드는 방법이 사용되고 있다.In addition to manganese oxide, an oxide of a metal such as copper oxide may be used as a catalyst.A method for producing the precipitate is to neutralize the metal nitrate, the sulfate of the metal and the chloride of the metal with an alkaline solution to obtain a precipitate, and then dry and calcining. A metal oxide is obtained, and then a metal oxide is molded together with a binder to finally form an ozone decomposition catalyst.
또한, 산화망간만으로는 성능이 낮으므로 조촉매로서 Co, Cu, Ni, Ag 등의 전이금속 또는 Pt, Pd, Rh 등의 백금족 금속을 첨가하여 촉매활성을 높여서 사용하는 경우도 있으며, 미국특허 제4,405,507호 및 제6,203,771호에는 촉매로 Pt의 귀금속을 사용하는 방법이 개시되어 있다.In addition, since manganese oxide alone has low performance, it may be used to increase the catalytic activity by adding transition metals such as Co, Cu, Ni, Ag, or platinum group metals such as Pt, Pd, and Rh as cocatalysts, and US Patent No. 4,405,507. And 6,203,771 disclose methods of using noble metals of Pt as catalysts.
또한, 촉매를 담는 담체에 대한 종래기술로는 미국특허 제4,416,800호, 제4,665,051호 그리고 4,348,360호에서 열내화섬유, 코일, 허니컴을 적용하는 방법 등이 개시되어 있다.In addition, the prior art for the carrier containing the catalyst is disclosed in US Pat. Nos. 4,416,800, 4,665,051 and 4,348,360, a method of applying heat-resistant fibers, coils, honeycomb and the like.
일반적으로 금속산화물계 오존분해 촉매의 성능을 결정하는 주요 요소로는 금속산화물의 크기, 표면적 그리고 입도분포 등을 들 수 있으나, 이러한 종래기술에 의한 촉매인 산화망간은 금속산화물의 크기, 표면적, 그리고 입도분포에 있어서 만족할 만한 결과를 내지 못하고 있으며, 산화망간을 타 금속산화물과 단순히 혼합하여 소성하는 방법을 채택하고 있어 그 성능이 뛰어나지 못하는 문제점이 있었다. 특히 환경문제가 특히 주목을 받는 근년에는 오존분해촉매에 있어서도 종래보다 더 높은 활성을 가지는 촉매가 요망되고 있다.In general, the main factors that determine the performance of the metal oxide ozone decomposition catalyst include the size, surface area and particle size distribution of the metal oxide, but the manganese oxide catalyst according to the prior art is the size, surface area, and The particle size distribution did not produce satisfactory results, and a method of simply mixing and burning manganese oxide with other metal oxides has a problem in that its performance is not excellent. In particular, in recent years when the environmental problem is particularly noticed, a catalyst having a higher activity than in the conventional ozone decomposition catalyst is desired.
본 발명은 전술한 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 미세한 산화망간과 산화칼륨이 형성되어 있는 것을 특징으로 하는 오존분해 촉매체와 과망간산칼륨으로부터 미세한 산화망간 및 산화칼륨을 제조하는 공정을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, a process for producing fine manganese oxide and potassium oxide from ozone decomposition catalyst body and potassium permanganate, characterized in that fine manganese oxide and potassium oxide is formed The purpose is to provide.

본 발명은 산화망간과 산화칼륨이 공존하는 것을 특징으로 하는 기체 중에 함유된 오존을 촉매적으로 분해하기 위한 오존분해용 산화망간계 촉매체를 제공한다.The present invention provides a manganese oxide catalyst body for ozone decomposition for catalytically decomposing ozone contained in a gas characterized by coexistence of manganese oxide and potassium oxide.
또한, 본 발명은 산화망간과 산화칼륨에 산화구리, 산화세륨, 산화아연, 산화란타늄 중 하나 이상을 더욱 포함하는 것을 특징으로 하는 오존분해용 산화망간계 촉매체를 제공한다.The present invention also provides a manganese oxide catalyst for ozone decomposition, characterized in that the manganese oxide and potassium oxide further comprises at least one of copper oxide, cerium oxide, zinc oxide, lanthanum oxide.
또한, 본 발명은 과망간산칼륨의 수용액을 준비하는 단계와 상기 수용액에 담체를 함침시키는 단계와 상기 함침된 담체를 수용액으로부터 분리하여 건조시키는 단계와 상기 건조된 담체를 소성하는 단계로 이루어지는 것을 특징으로 하는 오존분해용 산화망간계 촉매체의 제조방법을 제공한다.In addition, the present invention comprises the steps of preparing an aqueous solution of potassium permanganate, impregnating a carrier in the aqueous solution, separating the impregnated carrier from an aqueous solution and drying, and calcining the dried carrier Provided is a method for preparing a manganese oxide catalyst body for ozone decomposition.
또한, 본 발명은 상기 과망간산칼륨의 수용액을 준비하는 단계에 구리질산염, 세륨질산염, 아연질산염, 란타늄질산염 중에서 하나 이상을 추가하여 용해하는 것을 특징으로 하는 오존분해용 산화망간계 촉매체의 제조방법을 제공한다.In addition, the present invention is a method for producing a manganese oxide catalyst for ozone decomposition, characterized in that by adding one or more of copper nitrate, cerium nitrate, zinc nitrate, lanthanum nitrate in the step of preparing an aqueous solution of potassium permanganate. to provide.
우선 오존분해 촉매체의 제조방법을 단계별로 자세히 설명하면 다음과 같다.First, the method of preparing the ozone decomposition catalyst body will be described in detail as follows.
과망간산칼륨을 증류수에 용해하고, 금속질산염을 준비하여 과망간산칼륨의 수용액에 용해하며, 동시에 용해하여도 무방하다.Potassium permanganate is dissolved in distilled water, a metal nitrate is prepared and dissolved in an aqueous solution of potassium permanganate, and may be dissolved at the same time.
이 때 금속질산염은 조촉매를 첨가하는 것이므로 선택적으로 투입할 수 있다. 상기 금속질산염으로서 구리질산염, 세륨질산염, 아연질산염, 란타늄질산염 중 하나 이상을 선택할 수 있다.At this time, the metal nitrate can be added selectively because the addition of the promoter. As the metal nitrate, one or more of copper nitrate, cerium nitrate, zinc nitrate and lanthanum nitrate may be selected.
이 때 과망간산칼륨 또는 금속질산염의 농도는 최종 생산물에 따라 변경될 수 있는 것으로서, 20 gr/liter ~ 200 gr/liter 정도이면 바람직하다. 왜냐하면, 200 gr/liter 이상에서는 결정이 석출되고, 20 gr/liter 이하에서는 금속 담지량이 너무 작기 때문에 부적합하기 때문이다.At this time, the concentration of potassium permanganate or metal nitrate can be changed depending on the final product, it is preferable that the 20 to 20 gr / liter ~ 200 gr / liter. This is because crystals are precipitated at 200 gr / liter or more, and are unsuitable at 20 gr / liter or less because the amount of metal supported is too small.
과망간산칼륨과 금속질산염이 완전히 용해되면, 용해액에 담체를 함침한다. 담체로는 활성탄, 활성알루미나, 활성실리카, 제올라이트, 규조토, 코디어라이트 하니컴 중에서 선택할 수 있다.When potassium permanganate and metal nitrate are completely dissolved, the solution is impregnated with a carrier. The carrier may be selected from activated carbon, activated alumina, activated silica, zeolite, diatomaceous earth and cordierite honeycomb.
일정시간 함침이 끝나면, 여과를 거쳐 용해액을 제거하고 담체를 건조한다. 이 때 건조온도 및 시간은 담체의 종류에 따라 달라지며 통상적으로 50 ~ 150℃에서 5-10시간이 바람직하다.After a certain period of impregnation, the solution is removed by filtration and the carrier is dried. At this time, the drying temperature and time depends on the type of carrier, and typically 5-10 hours at 50 ~ 150 ℃.
그 이유는 50℃이하에서는 건조시간이 너무 길어 부적절하고, 150℃ 이상에서는 과망간산칼륨이 분해되기 시작하기 때문이다.The reason for this is that drying time is too long at 50 ° C or lower, which is inappropriate, and potassium permanganate starts to decompose at 150 ° C or higher.
이렇게 건조된 담체는 소성단계를 거쳐서 최종 산화망간계 촉매체가 얻어진다.The dried carrier is then calcined to obtain a final manganese oxide catalyst body.
소성온도 및 시간 또한 담체의 종류에 따라 달라지며 통상적으로 150~600℃에서 3-10시간이 바람직하다.The firing temperature and time also depend on the type of carrier and are usually 3-10 hours at 150-600 ° C.
그 이유는 150℃ 이하에서는 과망간산칼륨이 산화망간과 산화칼륨으로 전환되지 않아 부적절하고, 600℃ 이상에서는 폭발적으로 분해되기 때문에 작업의 위험성이 있기 때문이다.This is because potassium permanganate is not converted to manganese oxide and potassium oxide at 150 ° C. or lower, and is explosive.
이러한 제조방법에 의해 제조되는 촉매체는 다음과 같다.Catalyst bodies produced by such a production method are as follows.
소성단계에서 과망간산칼륨은 다음 식 (2)와 같은 반응이 일어난다.In the firing step, potassium permanganate reacts as in the following equation (2).
2KMnO4-> K2O + 2MnO2---------------- (2)2KMnO 4- > K 2 O + 2MnO 2 ---------------- (2)
따라서, 본 발명의 촉매체의 표면에는 미세한 산화망간과 산화칼륨이 분포된다.Therefore, fine manganese oxide and potassium oxide are distributed on the surface of the catalyst body of the present invention.
또한 타 금속질산염이 첨가된 경우에는 금속산화물로 변화하여 산화망간과 혼합된 상태가 된다.In addition, when other metal nitrate is added, it is converted into a metal oxide and mixed with manganese oxide.
본 발명에서 식 (2)의 반응에 의하여 얻어진 산화망간과 산화칼륨은 원자규모의 아주 작은 입자이기 때문에 미세하면서 담체의 전 표면에 균일하게 분포된 입자를 얻을 수 있다.In the present invention, since manganese oxide and potassium oxide obtained by the reaction of formula (2) are very small particles of atomic scale, fine and uniformly distributed particles on the entire surface of the carrier can be obtained.
또한, K2O가 산화망간과 공존함으로써 산화망간이 덩어리채 뭉쳐져서 편재되는 현상을 방지하여 오존이 반응할 수 있는 유효표면적으로 넓게 한다. 이러한 표면구조로 인하여 잔류오존을 효과적으로 분해할 수 있게 된다.In addition, since K 2 O coexists with manganese oxide, manganese oxide is agglomerated and prevents ubiquitous phenomenon, thereby widening the effective surface area where ozone can react. This surface structure makes it possible to effectively decompose residual ozone.
다음은 실시예에 의하여 본 발명의 제조방법을 설명한다.The following describes the production method of the present invention by examples.
<실시예 1><Example 1>
과망간산칼륨 1kg, 구리질산염 100g, 세륨질산염 100g을 10liter의 증류수에 용해하였다. 이 용액에 비표면적이 800m3/g 이상인 활성탄 펠렛을 2kg 첨가하여 5시간 방치하였다. 진공여과기로 여과한 후 함침활성탄을 70℃에서 10시간 건조하였다. 건조후 170℃에서 5시간 유지하여 과망간산칼륨이 분해되도록 하였다.1 kg of potassium permanganate, 100 g of copper nitrate, and 100 g of cerium nitrate were dissolved in 10 liters of distilled water. 2 kg of activated carbon pellets having a specific surface area of 800 m 3 / g or more were added to the solution and allowed to stand for 5 hours. After filtration with a vacuum filter, the impregnated activated carbon was dried at 70 ° C. for 10 hours. After drying for 5 hours at 170 ℃ to dissolve potassium permanganate.
이렇게 제조된 활성탄 담지 산화망간촉매를 사용하여 오존분해 실험을 하였다.Ozone decomposition experiments were carried out using the activated carbon-supported manganese oxide catalyst.
직경 5cm, 길이 10cm의 유리관에 활성탄 담지 산화망간촉매를 30cc 장입하고 오존 발생기에서 발생한 오존 5000ppm을 주입한 결과, 촉매층을 통과한 공기의 오존 함량을 조사한 결과는 0.5ppb이하로 검출되었다.When 30 cc of activated manganese oxide supported carbon was charged into a glass tube having a diameter of 5 cm and a length of 10 cm, and 5000 ppm of ozone generated from an ozone generator were injected, the ozone content of air passing through the catalyst layer was detected to be 0.5 ppb or less.
오존의 검출방법은 오존검출범위가 0.1~1ppb인 가스텍 검지관을 사용하였으며, 검지관은 오존이 있을 경우 청색에서 백색으로 변하게 된다. 본 실험을 1일 8시간씩 30일 이상 수행하여도 검지관이 청색을 유지하므로 오존의 분해효율은 99.99%이상인 탁월한 망간촉매가 만들어졌음을 확인하였다.As the detection method of ozone, a gastec detection tube with an ozone detection range of 0.1 to 1 ppb was used, and the detection tube changes from blue to white when ozone is present. Even if the experiment was carried out for 8 days or more for 30 days or more, the detection tube was kept blue, and it was confirmed that an excellent manganese catalyst having an ozone decomposition efficiency of 99.99% or more was made.
<실시예2>Example 2
과망간칼륨 1kg, 구리질산염 100g, 세률질산염 100g을 10liter의 증류수에용해한다. 이 용액에 비표면적이 20m3/g이상인 코디얼라이트 하니컴 담체를 1.5kg 첨가하여 5시간 방치한 다음 진공여과기로 여과하였다. 여과된 함침 하니컴 담체는 110℃에서 5시간 건조하고 건조후 600℃에서 5시간 유지하여 과망간산칼륨이 분해되도록 하였다.1 kg of potassium permanganate, 100 g of copper nitrate, and 100 g of trinitrate are dissolved in 10 liters of distilled water. 1.5 kg of cordial honeycomb carrier having a specific surface area of 20 m 3 / g or more was added to the solution, and the resultant was allowed to stand for 5 hours and then filtered by a vacuum filter. The filtered impregnated honeycomb carrier was dried at 110 ° C. for 5 hours and dried at 600 ° C. for 5 hours to decompose potassium permanganate.
직경 5cm, 길이 10cm의 아크릴관에 코디얼라이트 하니컴에 담지된 산화망간촉매를 30cc 장입하고 오존 발생기에서 발생한 오존 500ppm을 주입한 결과, 촉매층을 통과한 공기의 오존 함량을 조사한 결과는 50ppb로 검출되었다.30 cc of manganese oxide catalyst loaded on cordial honeycomb was charged into an acrylic tube 5 cm in diameter and 10 cm in length, and 500 ppm of ozone generated from an ozone generator was injected. As a result, the ozone content of the air passing through the catalyst layer was detected as 50 ppb. .
상기와 같이 만들어진 촉매체를 오존을 발생하여 악취를 제거하는 공기정화기에 적용하였다.The catalyst body made as described above was applied to an air purifier to remove odor by generating ozone.
도 1은 본 발명의 촉매체를 공기정화기에 적용한 예시도이다.1 is an exemplary diagram in which the catalyst body of the present invention is applied to an air purifier.
오존발생공기정화기의 작동원리는 송풍팬(10)에서 오염된 공기를 흡입한 후 오존발생장치(20)에서 오존을 발생하여 오염된 공기의 악취를 제거하고 배출된다. 이 경우 잔류오존의 경우 배출구(30)로 배출됨에 따라 인체에 유해한 오존 특유의 비릿한 냄새를 배출구에서 확인할 수 있다. 적용예에서는 본 발명의 촉매체를 소형 캐니스터(40)에 충진하여 잔류오존을 처리하도록 하였다. 배출구에서의 잔류오존을 확인하기 위하여 가스텍 검지관(50)을 사용하여 검지하였으나 잔류오존을 검출할 수 없음을 확인하였다.The operation principle of the ozone generating air purifier inhales the polluted air from the blower fan 10 and generates ozone from the ozone generator 20 to remove the odor of the polluted air and discharge it. In this case, as the residual ozone is discharged to the discharge port 30, a vivid smell peculiar to ozone harmful to the human body can be confirmed at the discharge port. In the application example, the catalyst body of the present invention was filled in the small canister 40 to treat residual ozone. In order to check the residual ozone at the outlet, the gastec detection tube 50 was used to detect the residual ozone.
미세한 입자의 산화망간과 알칼리 성분이 포함된 산화망간계 촉매체를 과망간산칼륨으로부터 비교적 용이하게 제조할 수 있으며, 잔류오존과의 접촉면적을 극대화하여 잔류오존의 분해 효과가 상당히 크므로 산업적 이용가치가 대단히 크며, 잔류오존이 인체에 미치는 악영향을 크게 줄일 수 있다.Manganese oxide-based catalyst bodies containing fine particles of manganese oxide and alkali can be prepared from potassium permanganate relatively easily, and the industrial ozone is valuable because the decomposition area of residual ozone is considerably large by maximizing the contact area with residual ozone. It is very large and can greatly reduce the adverse effects of residual ozone on the human body.
