Abstract

Defect-free γ-Al₂O₃ and La₂O₃-modified γ-Al₂O₃ membranes were prepared for recovery of acetone from nitrogen by multilayer diffusion and capillary condensation mechanisms. There existed an optimum range for acetone permeance (∼8 × 10^-7mol/m²·s·Pa) and acetone - nitrogen separation factor (∼1000) with respect to membrane temperature or feed composition. Hysteresises of acetone permeability and separation factor were also found between desorption and adsorption. The La₂O₃-modified γ-Al₂O₃ membrane appears to be the most effective for use in the VOC recovery process as compared to polymeric, Vycor, and unmodified γ-Al₂O₃ membranes.
