Preparation and characterization of high water perm-selectivity ZSM-5 membrane without organic template

▸ Preparing well hydrophilic ZSM-5 membranes without the organic template. ▸ The SiO2/Al2O3 ratio of the precursor synthesis gel of ZSM-5 membranes was 15. ▸ The crystallization time of the ZSM-5 membranes was shortened to 24 h. ▸ Effects of synthesis parameters on ZSM-5 membranes were investigated in details. ▸ ZSM-5 membranes had well H2O perm-selectivity for H2O/organic mixtures by PV.
