摘要

Carbon molecular sieve membranes (CMSM) were fabricated on sintered metal fibers (SMFs) by a template method using resorcinol–formaldehyde resin as precursor. The morphology and textural properties of the as-synthesized SMFs@CMSM composite were characterized by FTIR, BET and SEM, respectively. The adsorption performances of isopropanol in the structured fixed-bed adsorber based on the SMFs@CMSM composites were evaluated. The adsorption dynamic results showed that the mass transfer in the structured fixed-bed has been obviously enhanced via adding the SMFs@CMSM composites in the outlet. The length of unused bed (LUB) theory and Bed Depth Service Time (BDST) model were also applied to further analyze the bed utilization efficiency and adsorption dynamic data.
