Abstract
The removal characteristics of a mixed gas of ethyl acetate and 2-butanol by a biofilter packed with Jeju scoria were investigated. The experiments were conducted by changing the mixing ratio and the inlet loading rate of the mixed gas. There was no significant difference between the removal efficiency of ethyl acetate in the mixed gas and that of ethyl acetate in the single gas, while the removal efficiency of 2-butanol in the mixed gas was higher than that in the single gas. At the same loading rate, there was no significant difference between the removal capacity of_x000D_
ethyl acetate in the single gas and that in the mixed gas consisting of ethyl acetate at higher concentration than 2-butanol. However, the removal capacity of 2-butanol in the mixed gas was higher than that in the single gas when 2-butanol flowed through the biofilter at higher concentration than that of ethyl acetate.
