Biorefining is the process of "refining" multiple products from biomass as a feedstock or raw material much like a petroleum refinery that is currently in use. A biorefinery is a facility like a petroleum refinery that comprises the various process steps or unit operations and related equipment to produce various bioproducts including fuels, power, materials and chemicals from biomass. Industrial biorefineries have been identified as the most promising route to the creation of a new domestic biobased industry producing entire spectrum of bioproducts or bio-based products.

Biorefinery Process for Extraction, Separation, and Recovery of Fermentable Saccharides, other Useful Compounds, and Yield of Improved Lignocellulosic Material from Plant Biomass
ActiveUS20110129886A1Increase diversityIncrease probabilityCellulosic pulp after-treatmentBiofuelsFurfuralAqueous extract
Non-food plant biomass is subjected to hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C. and at a pH below about 7.0, to yield an aqueous extract containing hemicellulosic components, other wood-derived compounds, and a lignocellulosic residue. The separated aqueous extract or liquor is purified and concentrated through a multi-step process producing fermentable sugars. At each stage, inhibitory chemicals such as acetic acid, lignin, and furfural are separated and eventually recovered as commercial chemicals. The lignocellulosic residue may be further processed, as a material with enhanced resistance to sorption of water, for manufacture of improved pulp and paper, construction materials, pellet fuel, and / or other useful products.

Treatment Systems and Processes for Lignocellulosic Substrates that Contain Soluble Carbohydrates
InactiveUS20090061495A1Lowering capital cost per unit of ethanol producedImprove throughputBiofuelsFermentationDistillationPolymer
A biorefining process used to convert lignocellulosic biomass into ethanol via a fermentation pathway. In a first pretreatment process step, the biomass is mixed with an aqueous wash solution to remove soluble carbohydrates from the biomass structure. Next, the solid fraction is separated from a liquid fraction. In a second pretreatment process, the solid fraction is pre-treated to make the fiber bundles and complex polysaccharides more amenable to enzymatic hydrolysis. Following the second pretreatment process, the pre-treated biomass is subjected to one or more enzymes in a hydrolysis process. The liquid fraction isolated from the first pretreatment process is diverted past the second pretreatment process and is recombined with the solid fraction in the hydrolysis process. The enzyme cocktail in the hydrolysis process breaks down the alpha- and hemicellulose polymers into fermentable sugars. Finally, a fermentation process produces a “beer” that is further processed in a distillation and dehydration process.
