Biogas has become an attractive alternative energy source due to the limitation of energy from fossil.In this study, a new type of mixed matrix membrane (MMM) consisting of polyimide-zeolite was synthesized and characterized for biogas purification.The MMM consists of medium concentration of polymer (20% wt polyimide), 80% N-Methyl-2-pyrrolidone (NMP) and 25% zeolite 4A in total solid were prepared by a dry/wet phase inversion technique.

The fabricated MMM Thermo Actuator was characterized using SEM, DSC, TGA and gas permeation.Post treatment coating procedure was also conducted.The research showed that surface coating by 3% silicone rubber toward MMM PI 20% gave the significant effect to improve membrane selectivity.

The ideal selectivity for CO2/CH4 separation increased from 0.99 for before coating to 7.9 after coating for PI-Zeolite MMM, respectively.

The results suggest that PI-Zeolite MMM with good post treatment procedure will increase the GARLIC + RESHI membrane selectivity and permeability with more saver polymer requirement as well as energy saving due to low energy for mixing.
