Abstract

ZIF-8 membrane-based separation of propylene/propane is attractive for reducing the energy and cost of the conventional cryogenic distillation. However, the high-pressure permeation results are rarely reported on the tubular ZIF-8 membranes. In this work, high-quality ZIF-8 membranes were successfully fabricated on the tubular ceramic support. The coating of a PDMS layer can significantly improve the quality and reproducibility of as-synthesized membranes. The effect of permeating temperature (35–100 °C) and feeding pressure (1~6 bar) as well as the feeding compositions on the C₃H₆/C₃H₈ separation performance are carefully investigated. The C₃H₆/C₃H₈ permeation manners (with or without sweep gas, and under vacuum) on the tubular ZIF-8 membrane are also compared. Concentration polarization is only obviously existed when no sweep gas is used.
