Ethanol

Fermentation of AFEX-treated and enzymatically hydrolyzed forages and agricultural residues resulted in weak ethanol concentration in broths (maximum 5 g/L). A porous ethanol-selective membrane was evaluated on a model solution (2 wt/wt% ethanol) using pervaporation process. When used under permeate

This work reports the pervaporative separation of ethanol from ethanol –ethyl ter butyl ether mixtures using a commercial membrane, PERVAP 2256, that previously showed an interesting behavior in the separation of methanolMTBE mixtures. Pervaporation flux has been obtained and analyzed as a function

In order to stabilize the production of highly concentrated ethanol, a coupled fermentation/pervaporation process using ethanol permselective silicalite membranes coated with silicone rubber was studied. In case of the silicalite membrane without coating, the membrane flux and the ethanol concentrat

The pervaporation (PV) reactor is a new technology for reaction and separation. Techno-economic studies are showing that PV reactors have good market potential. The most common reaction system studied for the application of PV is an esterification reaction between an alcohol and an acid in the prese
