Synthesis and Characteristics of Al-containing ZSM-58 Zeolite Membrane for CO2 Separation

E. Hayakawa and S. Himeno
Abstract—We prepared an Al-containing ZSM-58 zeolite membrane and compared it with the separation performance of an all-silica ZSM-58 zeolite membrane. First, the ZSM-58 zeolite crystals were synthesized from a solution with the same membrane synthesis solution composition, and the characteristics of ZSM-58 zeolite crystals with a difference in Si/Al molar ratio were studied. As-made crystals should have high porosity and crystallinity. All-silica and Al-containing ZSM-58 zeolite membranes were applied in the separation of an equimolar CO2/CH4 and CO2/N2 mixture of pressure drop and temperature. The Al-containing ZSM-58 zeolite membrane showed a higher selectivity than the all-silica ZSM-58 zeolite membrane, which was confirmed at a lower temperature and feed pressure.

Index Terms—CO2 separation, DDR type zeolite, zeolite membrane, ZSM-58.
