Abstract Titanium silicalite-1 (TS-1) membranes were obtained on α-Al 2O3 capillaries by secondary growth of silicalite-1 seeds under microwave irradiation. TS-1 membranes were grown at 180-190 °C either on the outer side or on both sides of the capillaries, from sols with a molar ratio Si/Ti = 16-75. All the derived membranes were gas-tight before template calcination (no macro-defects) although the highest Si/Ti ratios lead to higher membrane quality with N2/SF6 > 100 for single gases and separation factors up to 65 for EtOH/H2O mixture separation by pervaporation (EtOH flux up to 2.2 kg/h m2 at 65 °C). The reproducibility of membrane performance, with good balance between flux and selectivity, is highly attractive for further industrial applications of these TS-1 membranes which are currently developed on multi-capillary modules.
