摘要:
PURPOSE: Spherical activated carbon and absorber for eliminating pollutants including the same are provided to increase the ratio of pores in the fine particles of the activated carbon to reduce the ratio of pores between the fine particles. CONSTITUTION: The average diameter of spherical activated carbon is between 0.38mm and 2mm. The specific surface area of the spherical activated carbon is 1,000m^/g or more based on a Brunauer-Emmett-Teller method. V_intra(%) of the spherical activated carbon is 50% or more and is represented by equation, V_intra(%)=V_d/V_total x 100. In the equation, V_total is the total pore volume before the pulverization of the spherical activated carbon; and V_d is the total pore volume of pulverized fine particles of 0.5um to 5um average diameter and is between 0.32cm^3/g and 0.39cm^3/g.본 발명은 흡착제로 사용하기 위한 다공성의 구형 활성탄소를 제공한다. 구형 활성탄소가 가진 전체 세공용적 중에서 활성탄소를 구성하는 미세입자 내에 형성된 세공의 비율이 높고 미세입자간 형성된 세공의 비율이 적은 본 발명에 따른 구형 활성탄소는 나노 크기의 피흡착 입자에 대한 우수한 선택흡착성능을 나타낸다.
