NOVELTY - A system for the production of ethanol from pre-treated biomass, comprises an apparatus configured to remove the inhibitors from the filtered liquid component, thus yielding a first treated liquid component, where the apparatus is in fluid communication with the filter to receive the filtered liquid component.    USE - The system is used for the production of ethanol from pre-treated biomass.    ADVANTAGE - The system for treating a component of lignocellulosic biomass has been pre-treated and separated to remove inhibitors from the component prior to fermentation in order to facilitate pentose fermentation resulting in an efficient and high yield production of ethanol.    DETAILED DESCRIPTION - A system for the production of ethanol from pre-treated biomass, comprises a source of pre-treated biomass; a centrifuge in fluid communication with the source of pre-treated biomass, where the centrifuge is configured to separate the pre-treated biomass into a liquid component and a solid component, where the liquid component comprises sugars; a filter comprising a pore size of 25-100 microns, where the filter is in fluid communication with the centrifuge to receive the liquid component to provide a filtered liquid component; an apparatus configured to remove the inhibitors from the filtered liquid component, thus yielding a first treated liquid component, where the apparatus is in fluid communication with the filter to receive the filtered liquid component; an evaporation system in fluid communication with the apparatus to receive the first treated liquid component to remove water from the first treated liquid component and produce a second treated liquid component; and a fermentation system in fluid communication with the evaporation system to receive the second treated liquid component, where the fermentation system comprises an ethanologen to ferment the sugars into ethanol; where the apparatus comprises an ion exchange system comprising a resin bed; where the resin bed comprises a resin capable of binding the inhibitors; where the biomass comprises lignocellulosic material; where the lignocellulosic material comprises one of corn cobs, corn plant husks, corn plant leaves and corn plant stalks.
