종래는 유해가스를 제거하기 위해 목재 야자각, 석탄, 피치, 셀룰로오스 섬유 및 화학섬유를 원료로 불활성가스로 처리하고 제조되는 일반활성탄을 사용하고 있다. 이에 관한 특허들이 많이 보고 되고 있다. 이들 특허에 사용하고 있는 활성 탄은 비교적 넓은 비표면적과 미세 세공이 잘 발달되어 있어 다양한 유기가스에 사용하기에 적절하지만 단순한 물리흡착의 문제(흡착과 탈착의 순환)를 가지고 있으며, 악취가스 중에 알데히드계 가스에 대한 흡착성능이 낮은 문제점이 있다.Conventionally, in order to remove noxious gas, wood activated carbon, coal, pitch, cellulose fibers and chemical fibers are treated with inert gas as a raw material. Many patents have been reported. The activated carbon used in these patents has a relatively large specific surface area and fine pores, so it is suitable for use in various organic gases, but has a simple physical adsorption problem (circulation of adsorption and desorption). There is a problem that the adsorption performance to the system gas is low.

상기 일반활성탄이 가지고 있는 물리흡착의 문제점을 해결하고 유해가스 제거 성능을 향상시킨 제품으로 화학반응을 이용한 화학흡착제 특허들이 다수 존재하나 알데히드류 가스를 효과적으로 제거하기에는 아직 성능이 부족한 문제가 있다.There are many chemical adsorption patents using chemical reactions to solve the problems of physical adsorption of the general activated carbon and improve the performance of removing harmful gases, but there is still a problem of insufficient performance to effectively remove aldehyde gases.

The present invention provides an adsorbent that is excellent in solving and removing aldehyde-based odors and harmful gases and suitable for use as a deodorizing filter medium.
