Abstract:
     A laminated zeolite composite characterized in that it comprises a FRI film being composed of a MFI type of zeolite and having a SiO2/Al2O3 (molar ratio) of 40 to 100 and a porous substrate being composed of a MFI type of zeolite and having a SiO2/Al2O3 (molar ratio) of 20 to 400 and the FRI film is formed on the substrate. The laminated zeolite composite combines excellent separation characteristics and high permeation performance capability.
