| Summary: | Different dope solutions for the alumina disk supported carbon membrane preparation for CO2/N2 and CO2/CH4 separation was formulated in this study. The prepared polymeric membrane made of commercial co-polyimide BTDA-TDI/MDI (P84) was carbonized at 700 °C under N2 gas flow. A defect-free membrane was obtained when high polymer composition was used. The disk supported carbon membrane with CO2/N2 and CO2/CH4 selectivity of 15 and 45, respectively, and CO2 permeance of 400 Barrer were obtained by one-step spray coating technique. The polymer composition of 12 wt% was concluded to be the optimum composition for the alumina disk supported carbon membranes. |
