SELECTIVELY ADSORPTIVE ACTIVATED CARBON, METHOD FOR PRODUCING SELECTIVELY ABSORPTIVE ACTIVATED CARBON SELECTIVELY ADSORBING TOLUENE FROM GASEOUS MIXTURE CONTAINING TOLUENE AND alpha-PINENE, AIR CLEANING AGENT AND DEODORANT

摘要

PROBLEM TO BE SOLVED: To provide activated carbon selectively adsorbing and removing volatile organic material such as toluene having small molecule diameter and causing sick house syndrome, malodor or the like while keeping fragrance of terpene or the like. SOLUTION: The activated carbon is provided with a slit-like micropore 11 having slit-like shaped opening 11a having≤0.8 nm slit width L1, wherein the distribution of the slit width L1 has a peak substantially only in 0.4-0.6 nm in the measurement by a t-plot method by nitrogen adsorption, the specific surface area of total pores is≥400 m2/g to the mass of carbonized material and the ratio of the specific surface area of the slit-like micropore is≥85% to the specific surface area of total pores.
