Synthesis of ZIF-8 tubular membrane via solvent evaporation seeding coupled with microwave assisted heating method for separation of small molecule gases
In this work, we systematically study the performance of tubular ZIF-8 membranes in the separation of small molecules including H2, CO2, N2 and CH4. The tubular ZIF-8 membranes were synthesized on α-alumina support via novel dual approach known as solvent evaporation seeding coupled with microwave...

In this work, we systematically study the performance of tubular ZIF-8 membranes in the separation of small molecules including H2, CO2, N2 and CH4. The tubular ZIF-8 membranes were synthesized on α-alumina support via novel dual approach known as solvent evaporation seeding coupled with microwave assisted growth. The durations for the growth of the seed layer through solvent evaporation and membrane layer via microwave heating were varied. The crystallinity and morphology of the resultant membranes were evaluated by using XRD, SEM and IFM analyses. The performance of the resultant tubular ZIF-8 membranes was assessed for small molecule gases permeation at various pressures and temperatures. Highest flux ranging from 0.02 to 0.61 mol/m2s were obtained for gases CO2, CH4, N2, and H2 at feed pressure of 10 bar, whereas highest ideal selectivity of 12.4, 9.3 and 6.9 were obtained for H2/CH4, CO2/CH4, N2/CH4, respectively, at feed pressure of 10 bar and temperature of 30 °C.
