Presented at: 7th Netherlands Process Technology Symposium (NPS7), Veldhoven, The Netherlands, 29-30 oktober 2007.

The expected high chemical and thermal stability of inorganic membranes compared to polymer membranes has resulted in a growing research activity with the aim of replacing these membranes with inorganic ones. Silica and methylated silica membranes do not meet these criteria. The application window of state-of-the-art Me-SiO2 membranes for use in dehydration processes is limited to only 95ÂșC. Recently, the preparation of microporous titania or zirconia membranes has been published. The selectivity of these membranes in pervaporation is too low at this moment.
