Abstract

A zeolite membrane fabrication process combining 2D-zeolite nanosheet seeding and gel-free secondary growth is described. This process produces selective molecular sieve films that are as thin as 100 nm and exhibit record high permeances for xylene- and butane-isomers.

Keywords: butane and xylene isomer separation; secondary growth; zeolite membranes; zeolite nanosheets.
