Abstract

Tubular carbon membrane was prepared from carbonization of P84 co-polyimide (PI) and nanocrystalline cellulose (NCC) which had been carbonized under Argon atmosphere at 800°C with a heating rate of 3°C/min. The resultant TCMs were aged for a specified duration (new, three days, one month, and three months) to study the effects of aging times on the oxygen separation properties (permeance and perm-selectivity) of TCMs. The investigation finding reveals that the aging times could be a factor that affects the transport properties of the fabricated membrane. The pores of the fabricated TCMs samples tend to shrink over time to reach a stable thermodynamic state. The results also showed that newly fabricated TCMs (no aging) possess the highest gas permeance and perm-selectivities over the aged TCM samples. The highest selectivity was achieved at 9.29±2.5.
