Adsorption dynamics of toluene in structured fixed bed with ZSM-5 membrane/PSSF composites

Adsorption experiments of toluene in different fixed beds were performed in a stainless steel tube (20 mm i.d., 30 mm length). A structured fixed bed filled with both GAC with bed height of 2.4 cm in the inlet of bed and ZSM-5/PSSF composites with bed height of 0.6 cm in the outlet of bed was designed.
