P84 Co-Polyimide-based Tubular Carbon Membrane: Effect of Pyrolysis Temperature

In this study, the effect of carbonization temperature on the performance of carbon membrane was being investigated. p84 co-polyimide-based tubular carbon membrane were fabricated through the dip-coating technique. the prepared membranes were characterized by using the thermogravimetric analysis and scanning electron microscopy. co_2, n_2, and ch_4 pure gas were utilized in determination of the carbon membrane’s permeation attributes. in order to enhance the membrane’s performance, carbonization process was performed in ar environment; with the flow rate of 200 ml/min. the carbonization process was done at various temperature, namely 600 ◦c, 700 ◦c, 800 ◦c and 900 ◦c in a constant heating rate of 3 ◦c/min. the increased in the temperature of carbonization leads to the production of small pores size carbon membrane. carbon membrane prepared at 800 ◦c showed the highest co_2/ch_4 and co_2/n_2 selectivity of 63.2±5.2 and 61.3±1.7, respectively.
