Superhydrophobic ceramic hollow fibre membranes for trapping carbon dioxide from natural gas via the membrane contactor system

The membrane contactor system is one of the most important technologies to trap CO2 from natural gas. To apply this technology, hollow fibre membranes with a superhydrophobic surface must be used, where were prepared kaolin clay through phase inversion/sintering technique and modified by three types fluoroalkylsilane (FAS) molecules (C6, C8, C10) at different immersion times (6, 24, 48,72 h) capture gas via contacting gas-liquid system. was chosen due its abundant availability an affordable price as well high amount hydroxyl (OH) group in which easily reacts FAS during grafting process. Superhydrophobicity distinguished Fourier transform infrared (FTIR), scanning electron microscopy (SEM), liquid entry pressure water (LEPw) measurement, contact angle (CA). lowest pore size grafted obtained for C8 about 1.32 ?m; it considered perfect target resistance. tested carbon dioxide (CO2) With increasing time immersion, hydrophobicity phenomena rose gradually until superhydrophobicity property obtained. Forty-eight hours proven sufficient obtain desired avoid wetting pores membranes. Besides, type separating based on LEPw angle. reduction pH observed after testing performance using separate absorbent value decreased 6.6 4.3 within 1 h, concludes success into removing
