본 발명은 탈취제 및 여과체 등으로 다양한 용도를 지니고 있는 흡착제 담체를 제조하는 공정의 구성에 관한 것이다. The present invention relates to a configuration of a process for producing an adsorbent carrier having various uses as a deodorant and a filter body.
본 발명은 탈취제 및 여과체 등으로 다양한 용도를 지니고 있는 흡착제 담체를 제조하는 공정의 구성에 관한 것이다. 현재 활성탄과 같은 흡착제 담지 여과체의 제작은 우레탄폼 등의 고분자 매질에 활성탄을 유기 바인더를 이용하여 담지하는 형태로 제작된다. 이와 같은 제작과정에서 유기 바인더에 의하여 많은 양의 흡착점이 감소된 상태에서 제작 되고 있으며, 이와 같이 흡착점이 감소된 상태에서 사용되고 있다. The present invention relates to a configuration of a process for producing an adsorbent carrier having various uses as a deodorant and a filter body. Currently, the preparation of the adsorbent carrying filter, such as activated carbon, is made in the form of supporting activated carbon in a polymer medium such as urethane foam using an organic binder. In this manufacturing process, a large amount of adsorption point is produced by the organic binder in a reduced state, and thus it is used in a state in which the adsorption point is reduced.
국내의 경우에는 악취물질의 처리에 대해서는 최근 국민 생활 수준이 향상되고 일상생활에 화학적 처리 제품 및 화학제품을 다수 접하면서 실내공기의 오염문제가 부각되고 있다. 특히 영, 유아를 비롯하여 청소년에서 성인까지 각종의 피부질환이 발생하고 있으며, 이러한 피부질환의 원인이 유기화합물에 의한 것으로 규명되고 있다. 따라서 많은 가정에서 공기정화기를 사용하기 시작하였으며, 공기정화기 의 성능 및 안정성에 대한 많은 논란이 일어나고 있다. 가장 안전하고 효율적인 처리법으로는 흡착법이 있으며, 흡착법은 흡착제의 성능이 가장 중요한 인자로 작용한다. 특히, 흡착제의 흡착량이 큰 변수로 작용한다. 현재 부직포 필터 또는 우레탄폼 등에 활성탄을 담지한 형태의 필터를 제작하여 전처리 여과체나 후처리 여과체로 사용하고 있다. 또는 활성탄층을 제작하여 이를 이용하고 있다. 이러한 여과체는 분진의 여과 기능과 더불어 기상물질의 흡착이 동시에 수행되고 있다. 여과체에 활성탄과 같은 흡착제를 담지하는 과정은 대부분 유기바인더를 이용하여 활성탄과 고분자 소재를 바인딩하는 방법으로 진행된다. 이러한 공정에서 많은 양의 유기 바인더가 활성탄에 흡착되어 흡착점의 감소가 일어난다. 또한 활성탄 층의 경우 재생 보다는 교체를 하고 있다. 따라서 본 발명에서는 흡착제의 구성을 기존의 흡착제와 촉매의 역할을 수행할 수 있는 전이금속 활성탄이 함께 구성된 흡착층을 제작할 수 있는 흡착제의 제조법에 관한 것이다. 기존의 산화티타니움이난 제올라이트 등 인체에무해한 담지체에 철, 니켈 등의 전이금속을 담지시킨 후 이를 메탄 또는 에틸알콜 등의 물질과 반응시켜 섬유상의 탄소를 지지체 위에서 구성하는 방법에 관한 것이다. In Korea, the treatment of odorous substances has recently improved the national standard of living, and the problems of indoor air pollution have been highlighted as many of the chemical treatment products and chemical products are exposed to daily life. In particular, various skin diseases are occurring from young children, infants, adolescents to adults, and the cause of such skin diseases is identified as organic compounds. Therefore, many households have started using air cleaners, and there is much debate about the performance and stability of air cleaners. The safest and most efficient treatment is adsorption, and the adsorption is the most important factor. In particular, the adsorption amount of the adsorbent acts as a large variable. At present, non-woven fabric filters or urethane foams are produced in a form in which activated carbon is supported and used as a pretreatment filter or a post treatment filter. Alternatively, an activated carbon layer is manufactured and used. Such a filter medium has a filtration function of dust and adsorption of gaseous substances is performed at the same time. The process of supporting an adsorbent such as activated carbon on the filter medium is mostly performed by binding activated carbon and a polymer material using an organic binder. In this process, a large amount of organic binder is adsorbed on the activated carbon to reduce the adsorption point. The activated carbon layer is also being replaced rather than regenerated. Therefore, the present invention relates to a method for preparing an adsorbent that can produce an adsorption layer composed of a transition metal activated carbon that can serve as a conventional adsorbent and a catalyst. The present invention relates to a method of forming fibrous carbon on a support by supporting a transition metal such as iron or nickel on a support body which is harmless to the human body such as a conventional titanium oxide or zeolite and reacting it with a substance such as methane or ethyl alcohol.
철, 니켈 등의 금속표면에서 산소가 존재하지 않는 상태에서 탄화수소 분위기하에서 가열하면 탄화수소가 열분해되어 표면에 탄소가 침적되게 된다. 이러한 반응은 석유화학공업에서 부반응으로 일어나 공정의 운전을 어렵게 하는 반응이다. 또한 최근에는 수소원료의 이용을 위하여 메탄, 에탄올, 메탄올 등을 열분해하여 주생성물로 수소를 얻고 발생된 탄소는 고정화하는 반응에 대한 연구와 공정개발이 이루 어지고 있다. 또한 분해조건의 조절에 의하여 발생되는 탄소의 형태를 섬유상의 탄소로 제조할 수 있으며, 섬유상 탄소 내부 공동인 형태로도 제조할 수 있다. 이러한 형태로 제조된 탄소의 경우 기존의 활성탄보다 수배의 흡착능을 나타내게 되므로 매우 우수한 흡착제로 사용될 수 있다. 이러한 최근에 규명된 탄화수소 열분해반응을 이용하여 본 발명에서는 부생성물인 탄소를 금속합금망 표면에 발생시켜 흡착능을 지닌 여과체를 제조법을 구성하고자 한다. 또한 이러한 반응에서 발생되는 부생성물은 청정연료로 사용될 수 있는 환경적 측면에서 매우 진보된 공정의 구성이라 할 수 있다.When heated in a hydrocarbon atmosphere in the absence of oxygen on metal surfaces such as iron and nickel, hydrocarbons are pyrolyzed to deposit carbon on the surface. This reaction occurs as a side reaction in the petrochemical industry and makes the operation of the process difficult. In recent years, research and process development have been carried out on the reaction of pyrolyzing methane, ethanol and methanol to obtain hydrogen as a main product and immobilizing the generated carbon for the use of hydrogen raw materials. In addition, the form of carbon generated by the control of the decomposition conditions can be produced in the form of fibrous carbon, it can also be prepared in the form of the inner cavity of the fibrous carbon. Carbon produced in this form can be used as a very good adsorbent because it shows the adsorption capacity of several times than the existing activated carbon. In the present invention by using the hydrocarbon pyrolysis reaction of the recently identified to produce a method of producing a filter medium having adsorptive capacity by generating carbon by-product on the surface of the metal alloy network. In addition, the by-products generated from these reactions can be said to constitute a very advanced process in terms of the environment that can be used as a clean fuel.
본 발명은 이러한 활성탄 충전층을 대체할 수 있는 새로운 흡착제 제조에 관한 것이다. The present invention relates to the production of new adsorbents which can replace such activated carbon packed beds.
이전의 연구자들에 의하여 발표된 바로는 섬유상 탄소의 제조에 효율적인 원료로 제시되는 것은 에탄올과 메탄올이며, 고온에서는 메탄이 사용될 수 있다. 메탄의 경우 현재 조사된 바로 가장 많은 양의 매장량을 지닌 화석원료이며, 메탄의 열분해에 의한 수소 생성은 많은 연구가 진행된 상태이다. 특히, 이때 발생되는 탄소를 사용하지 않으므로써 온실가스의 배출을 억제할 수 있다는 점에서 최근 주목되고 있는 기술이다. 또한 최근 수소 사용의 증가로 인하여 수소연료에 대한 수요가 증가하는 추세이다. 따라서 본 발명이 이루고자하는 기술은 생성되는 섬유상 탄소의 효율적 생성면에 있다. 본 발명에서 가장 중요한 기술은 최적의 섬유상 탄소를 생성시킬 수 있는 촉매상의 합금의 조성과 열분해반응의 온도범위에 관한 것이다. As previously published by researchers, ethanol and methanol are proposed as efficient feedstocks for the production of fibrous carbon, and methane can be used at high temperatures. Methane is a fossil raw material with the largest reserves currently investigated, and hydrogen production by pyrolysis of methane has been studied. In particular, it is a technique that has been recently attracting attention in that it can suppress the emission of greenhouse gases by not using the carbon generated at this time. In addition, the demand for hydrogen fuel is increasing due to the recent increase in the use of hydrogen. Therefore, the technology to be achieved in the present invention is in terms of efficient production of the fibrous carbon produced. The most important technique in the present invention relates to the composition of the catalyst phase alloy and the temperature range of the pyrolysis reaction which can produce the optimal fibrous carbon.
따라서 철, 니켈, 망간, 탄화규소, 탄소 등을 제올라이트, 산화티타니움 등에 담지한 형태로 제조하고 제조된 전이금속 담지 흡착제를 산소가 존재하지 않는 분위기에서 에탄올, 메탄올, 메탄 등의 원료가 주입된 상태에서 고온으로 가열하여 탄화수소의 탄소만이 그믈망에 점착되게하는 방법에 관한 것이다. 이때 산소는 존재하지 않아야 하며, 온도는 200 ~ 1100℃ 사이에서 유지한다.Therefore, iron, nickel, manganese, silicon carbide, carbon, etc. are prepared in the form of zeolite, titanium oxide, and the like, and the transition metal-supported adsorbent prepared by injecting raw materials such as ethanol, methanol, and methane in the absence of oxygen A method of heating to a high temperature at such that only the carbon of the hydrocarbon is adhered to the group. At this time oxygen should not be present, the temperature is maintained between 200 ~ 1100 ℃.
반응 진행 중 발생되는 미전환 원료는 반응기 외부로 배출되어 분리 후 재순환되며, 일부는 계 밖으로 배출되어 원료로 사용되며, 발생된 수소는 분리하여 타산업의 원료로 제공한다. 이러한 과정을 통하여 그믈망 형태의 섬유상 탄소가 점 착된 우수한 흡착능을 갖는 흡착제를 제조할 수 있다.Unconverted raw materials generated during the reaction are discharged to the outside of the reactor and recycled after separation. Some are discharged out of the system to be used as raw materials, and the generated hydrogen is separated and provided as raw materials for other industries. Through this process, it is possible to prepare an adsorbent having excellent adsorption capacity to which the fibrous carbon in the form of gram net forms.

본 발명에 의하여 제조된 섬유상 탄소 점착 흡착제는 기존의 제조되는 흡착제 보다 우수한 흡착능을 나타내며, 탈착효율도 높으므로 인하여 재사용이 가능한 제품을 제조할 수 있으며, 섬유상 탄소의 재생 불능시 이를 연소시키 후 재 제조를 할 수 있는 점에서 온실가스의 발생을 저하시키고, 폐기물의 발생을 감소시키며, 우수한 흡착능과 더불어 전이금속에 의한 저온 촉매반응에 의한 유해물질의 분해도 달성할 수 있는 매우 우수한 제품이라 할 수 있다.
