A novel gradient porous ZSM-5 membrane/PSSF (paperlike sintered stainless steel fiber) composite was prepared by the wet layup papermaking/sintering technique and a secondary growth process. The effects of crystallization time on the morphology, thickness, and Si/Al ratio of the ZSM-5 membranes were studied. The composites were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and N2 adsorption. Adsorption behaviors of isopropanol in structured fixed beds filled with granular activated carbon (GAC) or ZSM-5 particles in the inlet of the bed and ZSM-5/PSSF composites in the outlet of the bed were investigated. Adsorption breakthrough behaviors of isopropanol in fixed beds containing only GAC or ZSM-5 particles were also studied. Theoretical breakthrough curves were predicted using the Yoon–Nelson model and compared with the experimental results. Satisfactory agreement between the theoretical breakthrough curves and the experimental dat...
