Synthesis of NaA zeolite membrane on a ceramic hollow fiber

Nanocomposite MFI-alumina hollow fibre membranes prepared via pore-plugging synthesis: Influence of the porous structure of hollow fibres on the gas/vapour separation performance

“…These authors obtained relatively thick MFI films (about 30 m) with H 2 /SF 6 permselectivities about 30 and a pure H 2 permeance around 0.5 mol m −2 s −1 Pa −1 , but no quality testing was provided. Xu et al [15] prepared zeolite NaA membranes on ceramic hollow fibres (0.4 mm o.d. ), showing a continuous 5-m film with typical single gas permeances <0.05 mol m −2 s −1 Pa −1 .…”

Recent Progresses in Ceramic Hollow‐Fiber Membranes

“…Xu et al [47] synthesized a relatively high quality NaA zeolite membrane on a ceramic hollow-fiber support. Liu et al [27] [49] prepared thin microporous silica membranes on the outer surface of hollow-fiber ceramic (Al 2 O 3 ) substrates.…”

Dehydration of TFEA/water mixture through hydrophilic zeolite membrane by pervaporation

“…A zeolite membrane might be a good candidate for water pervaporation since it functions not only as a molecular sieve but also has a good physicochemical stability [4]. Therefore, the pervaporation using a zeolite membrane has been widely studied to separate either water from water/organic mixtures or organics from aqueous solutions [4][5][6][7][8][9][10]. Zeolite membranes such as NaA and NaY might be potentially applicable in a dehydration process because of their unique pore structure and an excellent hydrophilicity.…”
