摘要

Abstract

Growth process of the NaY zeolite membranes was investigated by fluoride-containing precursor synthesis gel. Compared with the fluoride-free precursor synthesis gel

the irregular NaY zeolite crystals were dissolved into amorphous by the fluoride-containing precursor synthesis gel initially

the amorphous contained the Y-type zeolite characteristic bands by the IR characterization. The fine square NaY zeolite crystals arose from the amorphous

which were accumulated and gradually grew into a dense NaY zeolite layer on the support surface after 6.5 h. Because the excessive NaY zeolites were dissolved by the strong alkaline and fluoride-containing precursor synthesis gel

there was plenty of amorphous on NaY zeolites layer for prolonging the crystallization time. The as-synthesized NaY zeolite membranes had a good separation performance and repeatability for separation of 10 wt% methanol (MeOH)/methyl methacrylate (MMA) mixture by pervaporation

the flux and separation factor were (1.27 ± 0.07) kg·m

and (4900 ± 1500) at 323 K

respectively. Besides

the NaY zeolite membranes were applied to separate the other short chain alcohol from the various alcohol/orga

nic ester and alcohol/organic ether mixtures

the NaY zeolite membranes showed high short chain alcohol perm-selectivity.
