본 발명은 금속 함유 및 금속 첨착 활성탄소섬유를 이용한 독성 및 유해성 가스의 제거를 위한 것으로, 군사용으로 사용되는 독성 가스로부터 호흡기를 보호해 주는 흡착제로서 방독면의 정화통에 충전하여 사용할 수 있을 뿐만 아니라 일반 산업시설에서 발생되는 황화수소, 염소가스 등과 같은 유해성가스를 효과적으로 제거하기 위하여 흡착탑에 충전하여 사용할 수 있는 흡착제거용 금속 함유 및 금속 첨착 활성탄소섬유의 제조방법과 그 용도에 관한 것이다.The present invention is for the removal of toxic and harmful gases using metal-containing and metal-impregnated activated carbon fibers, as an adsorbent to protect the respiratory organs from toxic gases used for military purposes, as well as filling the gas tank of the gas mask can be used in general industry The present invention relates to a method for preparing adsorption-removing metal-containing and metal-impregnated activated carbon fibers that can be used in an adsorption tower to effectively remove harmful gases such as hydrogen sulfide, chlorine gas, and the like, and their use.

군사용으로 사용되는 독성 가스로는 혈액작용제, 신경작용제, 질식작용제, 수포작용제가 있다. 이들 독성가스를 제거하기 위하여 2차 세계대전부터 활성탄에 은, 크롬, 구리를 첨착하여 사용하고 있으며, 황이나 인산을 첨착한 첨착활성탄은 암모니아 또는 아민같은 기체를 흡착하는데 이용되고 있다. 또한, 가성소다나 탄산나트륨, 요오드화칼륨이 첨착된 첨착활성탄은 황화수소, 메틸메르캅탄 가스를 흡착하는데 이용되고 있다. 그러나, 이들 첨착활성탄은 본 발명제품보다 흡착용량이 낮아 군사용 독성가스 제거를 위하여 정화통에 충진하였을 경우, 원하는 정화성능을 발휘하기 위해서는 전체적으로 두께가 두껍고 무게가 무거워지게 되어 방독면을 착용하였을 때 행동에 지장을 주게 되는 등 불편함이 크다. 또한, 일반 산업시설에서 사용되는 흡착탑에 충진하였을 경우는 충진량이 많아 흡착탑이 커지며 이에 따라 유지비가 많아지는 등 많은 단점을 가지게 된다. 한편, 최근에 활성탄의 장점을 지니면서 흡착특성이 월등한 활성탄소섬유가 개발되어 다양한 분야에 수요를 창출하고 있다. 활성탄소섬유는 활성탄에 비해 기체상 오염물질의 제거효율이 우수하여 적은 양으로도 활성탄과 같은 흡착용량을 나타낼 수 있고 쉽게 재생하여 사용할 수 있다. 특히 금속을 첨착하면 선택적 흡착이 가능하다. 따라서 본 발명은 활성탄소섬유 제조시 금속을 각각 또는 혼합하여 함유시키거나, 첨착시킴으로써 독성 및 유해성 가스의 제거에 효과적인 흡착기능성 신소재의 제조방법 및 용도에 관한 것이다.Toxic gases used for military purposes include blood agents, nerve agents, choking agents, and blisters. In order to remove these toxic gases, World War II has been using silver, chromium and copper impregnated with activated carbon. Impregnated activated carbon impregnated with sulfur or phosphoric acid is used to adsorb gases such as ammonia or amine. In addition, impregnated activated carbon impregnated with caustic soda, sodium carbonate or potassium iodide is used to adsorb hydrogen sulfide and methyl mercaptan gas. However, these impregnated activated carbons have a lower adsorption capacity than the present invention, so that when they are filled in the septic tank to remove toxic gas for military use, the overall thickness becomes heavy and heavy to show the desired purification performance. The discomfort is great. In addition, in the case of being filled in the adsorption tower used in the general industrial facilities, there are many disadvantages such as a large amount of filling and a large adsorption tower, thereby increasing the maintenance cost. Meanwhile, recently, activated carbon fibers having the advantages of activated carbon and superior adsorption characteristics have been developed to create demand in various fields. Activated carbon fiber has better removal efficiency of gaseous contaminants than activated carbon, so it shows the same adsorption capacity as activated carbon and can be easily recycled and used. In particular, by adhering metal, selective adsorption is possible. Therefore, the present invention relates to a method for producing and using an adsorption functional new material which is effective in removing toxic and harmful gases by incorporating or impregnating metals in the production of activated carbon fibers, or by impregnating them.

본 발명은 핏치에 금속을 적정량 첨가하여 용융방사한 후 산화, 탄화, 스팀 활성화를 거쳐 표면적이 넓고, 흡착력이 매우 우수한 섬유상 흡착제(활성탄소섬유)의 발명과 동시에 일반 활성탄소섬유에 금속을 첨착시킴으로써 특정 유해가스에 알맞은 흡착제를 제조하고자 한다. 또한, 그의 미세공 평균직경을 기존 활성탄소섬유보다 확대시켜 촉매의 담체로 사용할 수 있도록 하며 여러 금속을 첨가하여 다양한 종류의 독성 및 유해성 가스에 알맞는 흡착제를 제조하고 응용하는 기술을 포함한다.In the present invention, by adding a proper amount of metal to the pitch and melt spinning, through the oxidation, carbonization, and steam activation, the surface area is wide and the adsorption power of the fibrous adsorbent (activated carbon fiber) at the same time by attaching the metal to the general activated carbon fiber It is intended to prepare an adsorbent suitable for a specific harmful gas. In addition, the micropore average diameter of the active carbon fiber is expanded to be used as a carrier of the catalyst, and various metals are added to include various techniques for preparing and applying adsorbents suitable for various types of toxic and harmful gases.

The melt-spun pitch fibers are infused through an oxidation process and carbonized through a carbonization process. This metal-containing carbon fiber is activated with hot nitrogen and steam mixed gas to produce a porous fibrous adsorbent. Adsorption capacity has a large specific surface area and micropores should be exposed on the surface, so it is possible to manufacture various grades of metal-containing activated carbon fibers by controlling the mixing ratio of temperature, time and steam at the time of activation. Various kinds of activated carbon island db can be prepared.
