Abstract

Abstract

The dynamic adsorption of ethyl acetate on two adsorption beds filled with (a) activated carbon fiber (ACF) mesh and (b) ACF cloth were investigated. The effects of gas velocity through the two beds on the pressure drop and breakthrough curves were compared. Results indicate that the pressure drop increases exponentially with the gas velocity and linearly with the filler thickness. The pressure drop of beds filled with the ACF mesh is only one thirtieth of that filled with the ACF cloth under the same gas velocity and filler thickness. The breakthrough curves were well fitted by the dynamic adsorption equation derived by Wheeler and modified by Jonas, from which the breakthrough time at a defined purification degree was obtained. The bed filled with the ACF mesh is superior to that filled with the ACF cloth in the purification of the volatile organic compounds at high gas velocities.
