Abstract
Official abstract text for this publication.
A method of generating a refined a sugar stream that comprises xylose from a biomass hydrolysis solution, including contacting a biomass hydrolysis solution that includes a population of mixed sugars comprising xylose, an acid, and impurities, with a thermally-phase separable solvent such as a glycol solvent to form an extraction mixture; and separating from said extraction mixture a first stream including the thermally-phase separable solvent, acid, and impurities and a second, refined sugar stream that comprises xylose.
First claim
Opening claim text (preview).
The invention claimed is: 1. An extraction mixture comprising: a biomass hydrolysis solution that comprises water, a population of mixed sugars comprising xylose, an acid, and impurities; and a thermally phase separable solvent relative to the water of the biomass hydrolysis solution, wherein the extraction mixture is configured to separate into two phases with an increased temperature, wherein a first phase comprises the water of the biomass hydrolysis solution and a second phase comprises the thermally-phase separable solvent. 2. The extraction mixture of claim 1 , wherein the thermally-phase separable solvent includes 2-butoxyethanol, or 1-propoxy-2-propanol, or any combination thereof. 3. The extraction mixture of claim 1 , further comprising an alkanol. 4. The extraction mixture of claim 3 , wherein said alkanol is hexanol. 5. The extraction mixture of claim 3 , wherein said alkanol is 2-ethylhexanol. 6. The extraction mixture of claim 1 , wherein the thermally-phase separable solvent comprises a 2-butoxyethanol. 7. The extraction mixture of claim 1 , wherein the thermally-phase separable solvent comprises a 1-propoxy-2-propanol. 8. The extraction mixture of claim 1 , wherein the thermally-phase separable solvent is a glycol solvent.
