文摘

The effect of alumina (Al₂O₃) nano-particles on gas separation properties of poly(4-methyl-1-pentyne) known as TPX was evaluated. Mixed matrix membranes (MMMs) were prepared with various weight percent (5, 10, 15, 20 and 30) of alumina nano-particles through solution casting along with solvent evaporation method. TPX and consequent MMMs were characterized using FT-IR, SEM and TGA methods. The MMMs permselectivities were determined through pure CO₂ and CH₄ permeation measurement and CO₂/CH₄ selectivity calculation. SEM images demonstrated the proper dispersion of alumina nano-particles in TPX matrix. Results from gas permeation showed that the permeability of both CO₂ and CH₄ as well as CO₂/CH₄ selectivities were increased with increasing alumina content. Significant increase of CO₂ permeability (from 157.43 Barrer at 8 bar and no loading of Al₂O₃ to 527.78 Barrer at 8 bar and 30 wt% loading of Al₂O₃) and conspicuous enhancement of selectivity, from 7.73 to 12.51, were obtained in TPX MMMs. Keywords Poly(4-methyl-1-pentyne) TPX CO₂/CH₄ Separation Alumina Nano-particles Mixed Matrix Membranes
