Abstract

The global economy is completely dependent on energy. As an alternative to fossil fuels, bioethanol is unquestionably the most promising renewable fuel. However, bioethanol requires low contamination values of water (0.3% at maximum) for this application, so the dehydration of bioethanol is mandatory. Among available techniques, pervaporation is preferred owing to its energy-saving, cost-effective, and environmentally friendly qualities.To convert pervaporation in a competitive process for bioethanol dehydration, new membranes need to be developed with high permeability and selectivity combined with good chemical and mechanical stability at high temperatures, at a reasonable cost. Thus, the pursuit for the perfect membrane will continue within the scientific community.
