    Abstract: A process for simultaneous saccharification and fermentation of a cellulosic solids fraction extracted from a lignocellulosic feedstock. The viscosity of the cellulosic solids fraction is reduced by intermixing with a liquid carbohydrate stream. A suitable liquid carbohydrate stream is a de-lignified liquids fraction that was previously separated from the solids fraction during processing of the lignocellulosic feedstock. Alternatively, the viscosity of the solids fraction may be reduced by commingling with a liquid carbohydrate stream comprising one or more monosaccharides. The reduced-viscosity cellulosic solids fraction is then commingled with a fermentative microbial inoculant and a cellulosic biomass-degrading enzyme composition. The commingled mixture is maintained in a pressurized reaction vessel under elevated temperatures to enable simultaneous enzymatic hydrolysis of the cellulosic solids to monosaccharides and fermentation of the monosaccharides to produce an ethanolic beer. The ethanolic beer is distillable for recovery of fuel-grade ethanol and a stillage that may be further processed.

    Abstract: An apparatus for processing sugar cane to concurrently produce sugar from cane juice, and ethanol and other co-products from bagasse. The apparatus comprises equipment for separating a cane juice stream and a fibrous bagasse from a sugar cane feedstock, equipment for refining the cane juice, equipment for processing the fibrous bagasse for recovery therefrom of a cellulosic pulp and a liquor stream, equipment for saccharifϊcation and fermentation of the cellulosic pulp to produce a fermentation beer therefrom, and equipment for recovery of an ethanol stream from the fermentation beer. Legacy sugar mills may be retrofitted with a bagasse biorefining apparatus to concurrently produce ethanol and co-products, with existing cane juice extraction and processing operations.

    Abstract: A process for concurrent production of lignins, fuel alcohol, and biogas from lignocellulosic feedstocks. The process comprises: (1) pretreating a lignocellulosic feedstock to produce a solubilised liquid components stream comprising lignins, lignin-derived compounds, and a cellulosic pulp stream, (2) separating the liquid stream from the cellulosic pulp stream, (3) processing the liquid stream to separate and recover at least lignins, lignin-derived compounds, and semi-solid waste material, (b) processing the cellulosic pulp stream to saccharify and ferment the cellulose pulp to produce a beer which is then separated into fuel-grade alcohol and a waste stillage material, (4) anaerobically digesting the semi-solid waste material from the liquid stream and the waste stillage material to produce a biogas. The rate of anaerobic digestion can be manipulated by controllably supplying a portion of the monosaccharides produced from the cellulosic pulp. The cellulosic pulp stream may also be anaerobically digested.
