ABSTRACT

The adsorption of volatile organic compounds (VOCs) was carried out using an activated carbon fiber(ACF) filter in an automobile. The adsorption capacities of formaldehyde, toluene, and benzene on anACF filter were far better than those of a polypropylene (PP) mat filter and combined (PP+activatedcarbon) mat filter by batch adsorption in a gas bag. In a continuous flow of air containing toluene vaporthrough an ACF packed bed, the breakpoint time was very long, the length of the unused bed wasshort, and sharp “S” -type breakthrough curve was plotted soon after breakpoint, showing a narrowmass transfer zone of toluene on the ACF. The adsorption amount of toluene on the ACF filter wasproportional to the specific surface area of the ACF; however, the development of mesopores 2-5 nmin size on the ACF was very effective with regard to the adsorption of toluene. The ACF air clarifierfilter is strongly recommended to remove VOCs in newly produced automobiles.
