Pervaporative separation of bioethanol produced from the fermentation of waste newspaper

Abstract

In this study, a hydrophobic polymeric polydimethylsiloxane (PDMS) membrane was used for the pervaporative separation of bioethanol produced from fermentation of lignocellulosic biomass (waste newspaper) and glucose. As a preliminary study, the pervaporation permeation performance showed strong dependence on feed concentration and temperature. The pervaporation of bioethanol produced by the fermentation of waste newspaper by Saccharomyces cerevisiae decreased process performance. However, the process performance was restored reversibly by water cleaning. The pervaporative separation of bioethanol from the fermentation of waste newspaper was carried out without any significant decreasing process performance in the study.
