Abstract

Asymmetric carbon molecular sieve (CMS) membranes prepared from cellulose hollow fiber precursors were investigated for H₂/CO₂ separation in this work. The prepared carbon membrane shows excellent separation performance with H₂ permeance of 111 GPU and an H₂/CO₂ selectivity of 36.9 at 10 bar and 110 °C dry mixed gas. This membrane demonstrates high stability under a humidified gas condition at 90 °C and the pressure of up to 14 bar. A two-stage carbon membrane system was evaluated to be techno-economically feasible to produce high-purity H₂ (>99.5 vol%) by HYSYS simulation, and the minimum specific H₂ purification cost of 0.012 $/Nm³ H₂ produced was achieved under the optimal operating condition. Sensitivity analysis on the H₂ loss and H₂ purity indicates that such membrane is still less cost-effective to achieve ultrapure hydrogen (e.g., >99.8 vol%) unless the higher operating temperatures for carbon membrane systems are applied.
