- MFI membranes with equal film thickness were grown on graded alumina supports and modified by ion exchange or impregnation. Single gas permeances of CO2 and H2 were measured for all membranes. Both impregnation and ion exchange had a significant effect on the permeation properties of the membranes. The single gas CO2/H2 permeance ratios were 0.57, 0.82, 1.7 and 2.2 for silicalite-1, NaZSM-5, BaZSM-5 and silicalite-1 impregnated with Ca(NO3)2 , respectively. Selected membranes were tested for separation of a mixture of 90 kPa CO2 and 90 kPa H2 in the temperature range 25-400 °C. The separation factors at 25 °C were 0.7, 2.0 and 4.1 for silicalite-1, BaZSM-5 and impregnated silicalite-1, respectively and decreased with increasing temperature. The results show that the separation factor can be enhanced significantly by impregnation, lowering of the Si/Al ratio or ion exchange.
