Abstract

SAPO-34 hollow fiber zeolite membranes are successfully synthesized on α-Al₂O₃ hollow fiber ceramic substrates by secondary growth method, and used to separate H₂ from a binary mixture (H₂, C₃H₈) or ternary mixture (H₂, C₃H₈, and C₃H₆) under a wide temperature range (25–600°C) with the aim of using them for propane dehydrogenation (PDH) reactions at high temperature. The results show excellent performance for H₂/C₃H₈ and H₂/ C₃H₈ & C₃H₆ separation, with high H₂ permeance of 3.1 × 10⁻⁷ mol/m²/s/Pa and H₂/C₃H₈ selectivity of 41 at 600°C. Additionally, the membrane shows stable performance for 140 hr of H₂/C₃H₈ separation test at 600°C. The high performance of this membrane is mainly attributed to the thin (∼2 μm) zeolite layer and asymmetric-wall of the hollow fiber support. So far, this membrane offers the highest hydrogen permeation and selectivity for H₂/C₃H₈ separation at high temperature (600°C) compared to those reported in literature.
