Abstract
This invention presents a metal-doped zeolite membrane-based apparatus containing molecular sieving zeolite thin film on the seeded porous substrate. The metal-doped zeolite membrane exhibits high selectivity to olefin over paraffins. The membrane is synthesized by seed coating and secondary growth method, followed by metal doping and post treatment processes.
