Ion exchanged zeolite
WebHydrothermally synthesized, ZSM-5 zeolite membranes (Si/Al=25 and 600) were ion exchanged with H +, Na +, K +, Cs +, Ca 2+ and Ba 2+ cations, and the membranes were stable after exchange. Their gas permeation properties were measured over the temperature range of 323–523 K. WebNarin G, Albayrak ÇB, Ülkü S.
