NOVELTY - Biorefinery comprises: a system for preparing the biomass into prepared biomass; a system for pre-treating the biomass into pre-treated biomass; a separator for separating the pre-treated biomass into a first and second components; a first treatment system for liquefying the first component by application of first enzyme formulation into liquefied first component; a second treatment system for treating the liquefied first component into treated first component by application of second enzyme formulation; and a fermentation system configured to produce the fermentation product.    USE - The biorefinery is useful for producing a fermentation product (ethanol) from biomass (all claimed).    ADVANTAGE - In the biorefinery system, the inhibitory components (including liquid components, residual lignin and other non-fermentable matters) are treated to remove the components, thus improves the efficiency of fermentation.    DETAILED DESCRIPTION - Biorefinery comprises: a system for preparing the biomass into prepared biomass; a system for pre-treating the biomass into pre-treated biomass; a separator for separating the pre-treated biomass into a first component comprising glucan and a second component comprising xylose; a first treatment system for liquefying the first component by application of a first enzyme formulation into a liquefied first component; a second treatment system for treating the liquefied first component into a treated first component by application of a second enzyme formulation so that glucose is made available; and a fermentation system configured to produce the fermentation product from the treated first component, where the fermentation product is produced by fermentation of glucose into ethanol, the biomass comprises lignocellulosic material, the lignocellulosic material comprises at least one of corn cobs, corn plant husks, corn plant leaves or corn plant stalks and the first enzyme formulation comprises a cellulase enzyme mixture. INDEPENDENT CLAIMS are also included for:    (1) producing a fermentation product from biomass comprising: preparing the biomass into prepared biomass; pre-treating the biomass into pre-treated biomass; separating the pre-treated biomass into a first component comprising glucan and a second component; treating the first component by application of a first enzyme formulation into a liquefied first component; treating the liquefied first component by application of a second enzyme formulation so that glucose is made available; and supplying an ethanologen to the treated first component so that the glucose can be converted to ethanol; and    (2) a continuous process for making ethanol from biomass, comprising: providing a continuous stirred tank reactor (CSTR) (710) with an outlet stream that is in fluid communication with at least two batch reactors (720); pre-treating the biomass into pre-treated biomass; separating the pre-treated biomass into a 6C solid (700) comprising glucan and a second component; continuously feeding the 6C solid into the CSTR and treating the 6C solid with a first enzyme (740) formulation in order to liquefy the 6C solid into a 6C slurry; continuously feeding the 6C slurry from the CSTR into at least one of the batch reactors, where the 6C slurry is treated in the batch reactors with a second enzyme formulation so that glucose is made available; and fermenting the glucose to form a fermentation product (780) comprising ethanol.
