Separation of Aqueous Isopropanol Through Chitosan/Poly (Vinyl Alcohol) Blended Membranes by Pervaporation

International Islamic University Malaysia Engineering Journal, 2012
Blend membranes consisting of chitosan/poly (vinyl alcohol) (CS/PVA) were prepared from a solution casting method and characterized via the pervaporation separation of isopropanol-water mixtures.  The solution of pure chitosan was blended with poly(vinyl

Advancing the organosolv biorefinery. Part I: Vapor stripping–vapor permeation for the recovery of 1‐butanol from aqueous solutions

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 1, Page 125-135, January/February 2026.
Abstract The industrial implementation of many lab‐scale biorefinery designs has been significantly hampered by the lack of availability of efficient and cost‐effective chemical recovery techniques. This is of particular importance for organic solvent‐based biorefineries such as those that use or produce aqueous butanol–water streams which, based on ...
