“…1 Furfural can be used as a raw material to synthesize various chemicals, including more than 1600 commercial products. [2][3][4] The state-of-art technology to separate furfural after the hydrolysis process is generally carried out by distillation, especially in small-scale factories. 3,4 However, this method is neither energy-efficient nor economical since it consumes a large amount of energy (about 20 tons of steam/furfural) and discharges a tremendous amount of wastewater with a significant amount of furfural produced.…”

In this study, polydimethylsiloxane/tetraethyl‐orthosilicate (PDMS/TEOS) hybrid materials with different TEOS ratios were synthesized by cross‐linking method. Ceramic tube‐supported PDMS/TEOS membranes were fabricated by dip‐coating method. Effect of TEOS content, feed concentration, and feed temperature through separation of a furfural–water mixture by pervaporation (PV) technology was investigated. The highest PV performance was obtained with the total flux of 1.19 kg/m2h with TEOS content of 1.8 g, furfural feed concentration of 30 wt.%, operating temperature, and vacuum pressure at 100 kPa and 50 °C, respectively. PDMS/TEOS was successfully synthesized and coated on ceramic tube‐supported with a thickness of 15 μm. The ceramic tube‐supported membrane demonstrated good hydrophobicity with a contact angle of 109.5° and excellent thermal stability at 450 °C. The obtained results demonstrated that the ceramic tube‐supported PDMS/TEOS membrane is potent to be utilized for the separation of the furfural‐water mixture by PV technology.
