Study on the stability of facilitated transport membrane in Hydrogen purification

The stability of membrane was evaluated in long term experiments at constant operation condition. Obtained results showed that the CO2 permeance and CO2/H2 selectivitywere decreased about 60% and 65% from their starting values, respectively and became constant and after that no morechanges were observed on membrane performance. Addition of cross linking agents to the gel containing carrier could successfully sustained the membrane performance
