A new route for fast crystallization of LTA zeolite by using highly efficient NaY seed solution as a silica source was demostrated.

Predicting benzene permeation fluxes in NaY zeolite membranes;

This work describes a novel method to synthesize NaY zeolite at high temperature(100-140 ℃)by using NaY seeds solution as a silica source,which is also a method for the activation of silica source in the synthesis of NaY zeolite.

TiO2 nanoparticles were prepared on NaY zeolite by impregnation of tetrabutyl titanate solution and calcination.

Preparation of NaY Zeolite Membrane and Its Application in Separation of Benzene/Cyclohexane by Pervaporation;

NaY zeolite membranes were synthesized on outer surface of α-Al2O3 ceramic tube by hot impregnation for introducing seed crystal and successive crystallization one cycle after the other.
