Title: Bioelectrochemical biorefining for the conversion of hydrogenous matter to hydrogen gas and other useful products

Abstract

A method for the substantially complete conversion of hydrogenous matter to higher value product, the method comprising: (i) subjecting the hydrogenous matter to a substantially complete deconstruction process in which an aqueous phase containing a multiplicity of deconstructed compounds is produced; and (ii) contacting the aqueous phase with an anode of a microbial electrolysis cell, the anode containing a community of microbes thereon which oxidatively degrade one or more of the oxygenated organic compounds in the aqueous phase to produce protons and free electrons at the anode, wherein the protons and free electrons are transported to the cathode to produce hydrogen gas or a valuable reduced organic compound at the cathode upon application of a suitable cell potential across the anode and cathode. The invention is also directed to an apparatus for practicing the method described above.
