BIO-ELECTROCHEMICAL REACTOR WITH DOUBLE BIO-ANODE, METHOD FOR ANODIC REGENERATION AND USE OF THE REACTOR FOR MICROBIAL ELECTROSYNTHESIS

摘要

The bioelectrochemical reactor (1) comprises: - an anode compartment (11) comprising at least two bioanodes (12, 13), and an anode electrolyte (14) comprising anode electroactive microorganisms, - a cathode compartment ( 21) comprising at least one bio-cathode (22), and a cathode electrolyte (24) comprising cathode electro-active microorganisms, the anode compartment (11) being separated from the cathode compartment (21) by, going from the anode compartment towards the cathode compartment, a cation exchange membrane (31) and an anion exchange membrane (32), said cation and anion exchange membranes being separated from each other by an inter-membrane compartment (30 ), - means for applying a potential difference between the bio-anodes connected to each other and the bio-cathode, the bio-cathode (22) having an active surface greater than the total active surface of the two bio- anodes (12, 13). Method for regenerating the activity of the bio-anodes of the reactor and use of said reactor for the electrosynthesis of organic acids and / or alcohols from organic waste.
