Abstract
Membran gabungan terdiri dari 0,2-0,4% berat komposit karbon-zeolit yang terdispersi ke dalam BTDA-TDI/MDI (P84) telah dipreparasi melalui metode inversi fasa dengan N-metil-2-pirolidon (NMP) sebagai pelarut. Membran dikarakterisasi dengan X Ray Difraction (XRD), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Thermogravimetric Analysis (TGA), Fourier Transform Infrared (FTIR). Membran diuji kinerjanya dengan permeabilitas gas tunggal CO2 dan CH4. Permeabilitas maksimum CO2 dan CH4 berturut-turut yaitu 13,84 Barrer dan 12,68 Barrer dicapai dengan menambahkan 0,4% berat komposit karbon-zeolit. Membran BTDA-TDI/MDI (P84)/komposit karbon-zeolit menunjukkan peningkatan pada selektivitas ideal CO2/CH4 sebesar 3,490 jika dibandingkan dengan membran BTDA-TDI/MDI (P84) murni.
======================================================================Mixed Matrix Membranes (MMMs) which consist of 0.2–0.4 wt.% carbon-zeolite composite dispersed in BTDA-TDI/MDI (P84) have been prepared through phase inversion method by using N-methyl-2-pyrrolidone (NMP) as solvent. Membranes were characterized by X-Ray Difraction (XRD), Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Thermogravimetric Analysis (TGA), and Fourier Transform Infrared (FTIR). Membrane performance was measured by single gas permeation of CO2 and CH4. The maximum permeability of CO2 and CH4, which up to 13,84 Barrer and 12,68 Barrer, respectively, was achieved by incorporating 0.4 wt.% of carbon-zeolite composite. BTDA-TDI/MDI (P84)/carbon-zeolite composite mixed matrix membrane also showed a great enhancement in ideal selectivity of CO2/CH4 3.49 compared to the pure BTDA-TDI/MDI (P84) membrane.
