In this paper, the adsorption characteristics of a binary gas
system involving toluene and benzene on sulfuric acid treated
activated carbon (S-AC) are studied. As adsorption characteristics,
breakthrough curve and adsorption capacity were evaluated using
a flow-typed fixed-bed system for the effect of acid treatment of
activated carbon during VOCs adsorption. The purpose of this study
is to analyze the adsorption behavior of mixed VOCs on activated
carbon and sulfuric acid treated activated carbon for supplementing the scant information regarding the adsorption of VOCs
mixtures.
