Abstract

Emisi gas rumah kaca terus mengalami peningkatan, dimana CO2 merupakan kontributor utama dalam emisi gas rumah kaca sehingga perlu adanya upaya untuk mengurangi konsentrasi CO2 di atmosfer melalui pemulihan dan penyimpanan karbon serta pemanfaatan karbon. Penelitian ini bertujuan untuk mengetahui kinerja pemisahan gas CO2/N2 dan H2/CO2 dari membran PSf dengan penambahan PPs pada jumlah kecil (1%; 5%; 10% b/b). Pada penelitian ini telah berhasil difabrikasi membran dengan matriks polimer polisulfon dan material pengisi PPs dengan pemuatan pengisi sebesar 1%; 5%; dan 10% b/b relatif terhadap polisulfon. Membran PSf/PPs difabrikasi menggunakan metode inversi fasa (NIPS). Hasil karakterisasi menggunakan FTIR dan SEM menunjukkan adanya pengaruh penambahan PPs dan pelapisan PDMS terhadap struktur maupun morfologi pada membran PSf dan PSf/PPs. Permeabilitas gas CO2 dan N2 tertinggi diperoleh pada membran PSf/PPs 5% b/b-PDMS. Sedangkan permeabilitas gas H2 tertinggi terjadi pada membran PSf/PPs 10% b/b tanpa pelapisan PDMS. Selektivitas membran mengalami peningkatan dengan adanya pelapisan PDMS. Hasil dari perbandingan menggunakan diketahui bahwa membran PSf dan PSf/PPs baik dengan dan tanpa pelapisan PDMS masih berada di bawah garis Robeson. Membran yang paling mendekati garis Robeson adalah membran PSf/PPs 5% b/b dengan pelapisan PDMS untuk pemisahan CO2/N2 dan membran PSf/PPs 10% b/b tanpa pelapisan PDMS untuk pemisahan H2/CO2.

Greenhouse gas emissions continue to increase, where CO2 is the main contributor to greenhouse gas emissions, so efforts are needed to reduce CO2 concentrations in the atmosphere through carbon recovery and storage and carbon utilization. This study aims to determine the gas separation performance of CO2/N2 and H2/CO2 from PSf membranes with the addition of PPs in small amounts (1%; 5%; 10% w/w). In this study, a membrane was successfully fabricated with a polysulfone polymer matrix and PPs filler material with a filler loading of 1%; 5%; and 10% w/w relative to polysulfone. PSf/PPs membranes were fabricated using the phase inversion method (NIPS). The results of the characterization using FTIR and SEM showed that the addition of PPs and PDMS coating had an effect on the structure and morphology of the PSf and PSf/PPs membranes. The highest CO2 and N2 gas permeability was obtained on the 5% w/w-PDMS PSf/PPs membrane. Meanwhile, the highest H2 gas permeability occurred in 10% w/w PSf/PPs membrane without PDMS coating. Membrane selectivity has increased with the presence of PDMS coating. The results of the comparison using PSf and PSf/PPs membranes both with and without PDMS coating are still below the Robeson line. The membranes closest to the Robeson line are 5% w/w PSf/PPs membranes with PDMS coating for CO2/N2 separation and 10% w/w PSf/PPs membranes without PDMS coating for H2/CO2 separation.
