Fund Project:

The crystal structure of silicalite-Ⅰ zeolite could be improved by acid and/or hydrothermal treatments.The adsorption selectivity as well as the separation factor for ethanol-water mixture were found to be increased by such a treatment.Especially,the silicalite-Ⅰ obtained after successive acid and hydrothermal treatments filled polydimethyl-siloxane rubber membranes showed a separation factor for ethanol-water mixture up to 30.
