Abstract
In this work, a series of mixed matrix membranes (MMM) were produced by incorporating zeolite-T particles into the polysulfone (PSf) membrane. Membranes obtained were characterized using Field Emission Scanning Electron Microscope (FESEM), Energy Dispersion X-Ray (EDX) and the permeability and selectivity of CO2/CH4 of the membranes were tested. For pure polysulfone membrane, the permeability obtained were 12.33 and 4.69 for CO2 and CH4 respectively, meanwhile the CO2/CH4 ideal selectivity was 2.63. The results showed that by incorporating 4 wt% of zeolite-T into polysulfone, a highest CO2/CH4 ideal selectivity of 3.37 was obtained. Meanwhile, the highest permeability value for CO2 and CH4 of 82.3 GPU and 31.2 GPU respectively were obtained by using polysulfone membrane loaded with 3wt% of zeolite-T particles. Overall, all the resultants MMM showed higher permeability and selectivity compared to pure polysulfone membrane.
