Abstract

High-permeance ZSM-5 zeolite membrane was prepared on porous tubular α-Al₂O₃ support by varying-temperature hydrothermal synthesis. XRD patterns show that the membrane consists of ZSM-5 zeolite crystals. SEM analysis indicates that few defects exist in the membrane and the thickness of the membrane is about 9 μm. The hydrogen permeance through the membrane is about 2.4×10^-6mol/(m² · s · Pa), and the separation factor for n-C₄H₁₀/i-C₄H₁₀ mixture (volume ratio 1 : 1) is 40, which indicates that it has a high quality with high permeance and selectivity. Repeated nucleation and re-growth of the crystals on the support result in the dense membrane formation.
