Effective hydrogen purification from methane via polyimide Matrimid (R) 5218-Deca-dodecasil 3R type zeolite mixed matrix membrane
The demand for purified hydrogen as a new green energy source has dramatically increased during last years. In this study, different-Matrimid (R) - Deca-dodecasil 3R (DDR) type zeolite mixed matrix membranes were synthesized for Hydrogen purification from Methane. Results demonstrated that existence of DDR into the Matrimid matrix, as well as, high temperature thermal treatment enhances membrane crystallinity. Scanning electron microscope images of membranes showed uniform dispersion of zeolite in polymer matrix and well contact at polymer and zeolite interface. Gas permeation experiments exhibits that due to molecular sieving effect of DDR membrane Hydrogen permeabilities and Hydrogen/Methane selectivity enhance for 20 wt % loading of Deca-dodecasil 3R to 34.90 Barrer (100%) and 375.27 (189%), respectively.
