Abstract

Pada penelitian ini, membran karbon P84-kopoliimida / komposit karbon-zeolit (KKZ) pada tubular α-alumina dengan variasi komposisi KKZ telah disintesis melalui metode dipcoating-evaporation untuk pemisahan gas. Adanya perlakuan sintering dan pelapisan interlayer karbon pada tubular alumina yang digunakan menyebabkan pori alumina menyempit dan interlayer berfungsi sebagai jembatan penghubung antara membran dengan pendukung. Peningkatan kinerja pemisahan gas secara optimum terjadi pada penambahan KKZ sebesar 0,3% berat. CM P84/KKZ (0,3% berat) memiliki perkiraan kinerja pemisahan gas yang lebih baik daripada CM P84. Permeabilitas P84/KKZ (0,3% berat) adalah CO2 (1502 x 104 barrer), O2 (868 x 104 barrer), N2 (153 x 104 barrer), CH4 (1,6 x 104 barrer) dan selektivitasnya CO2/CH4 (935,49) > N2/CH4 (95,60) > CO2/N2 (9,79), dan O2/N2 (5,64). Dengan adanya pengaruh temperatur, transportasi gas mengikuti mekanisme molecular sieving karena permeasi meningkat dengan adanya kenaikan temperatur. ============= In this study, a P84-copolyimide/ zeolite composite carbon (ZCC) carbon membrane with various composition of ZCC have been prepared by dipcoating-evaporation method for gas separation. α-alumina tube was treated with sintering and carbon interlayer coating before dipcoating process. Consequently, the pore volume of alumina decreased by sintering and the interlayer acted as a bridge to link the membranes and support. Gas separation performance prediction of CM P84/ZCC have been studied from gas permeation of CH4, CO2, O2, and N2, and H2. CM P84/ZCC with addition 0.3% wt of ZCC shows hight selectivity. The permeability of CM P84/ZCC (0.3% wt) was CO2 (1502 x 104 barrer), O2 (868 x 104 barrer), N2 (153 x 104 barrer), CH4 (1,6 x 104 barrer). The selectivity of CM P84/ZCC (0.3% wt) was CO2/CH4 (935,49), O2/N2 (5,64), N2/CH4 (95,60), and CO2/N2 (9,79). Permeance increased with increasing of temperature, showed molecular sieving mechanism in gas transportation through membranes.
