“…There is still no gas separation process worldwide in operation using zeolite membranes. Ambitious aims for the development of an industrial process for xylene isomer 92 and butene isomer 223 separation using MFI membranes could not be realized yet. Despite excellent lab test results and successful scale-up work, the industrial installation of SAPO-34 and DD3R membranes in the CO 2 /CH 4 separation could not be realized either.…”

“…Among these membranes, two families are particularly interesting for gas separation: -MFI-type membranes for high-temperature separation of linear and branched paraffin isomers by molecular-sieving [5][6][7][8], -FAU-type membranes for CO 2 separation in pre-and post-combustion applications, as well as in the purification of natural gas and biogas. All these separations rely on the preferential CO 2 adsorption on the FAU material [9][10][11][12].…”

“…This can be achieved in practice by means of electrostatic attachment with control of pH or charge [6]. Masking the support during hydrothermal synthesis helps avoiding to a certain extent zeolite crystal growth in the support porosity and promotes the synthesis of extremely thin well-intergrown polycrystalline silicalite-1 layers (about 0.5 μm thickness) [7,13]. Specific zeolite crystal orientation in the layers can be also achieved by finetuning the seed characteristics (size, shape, concentration) [8] and by hydrothermal synthesis using polycationic templates favoring preferential growth along a specific crystallographic direction [14].…”

“…Several preparation methods have been developed, such as in situ hydrothermal synthesis [6][7][8], vapor phase transport method [9], secondary growth method [10][11][12] or embedding microcrystals of zeolite into a matrix [13]. Ideally, for a better separation performance, zeolite membrane should preferably be made of pure zeolite crystals with uniform and small particle size.…”
