Abstract: A method comprising: (a) providing a partially processed sucrose crop product containing at least 2% optionally at least 5% of the sucrose content of said crop at harvest on a dry solids basis, cellulose and lignin; (b) hydrolyzing said partially processed crop product with HCl to produce an acid hydrolyzate stream and a lignin stream; and (c) de-acidifying said hydrolyzate stream to produce a de-acidified sugar solution and an HCl recovery stream. Additional, methods, systems and sugar mixtures are also disclosed.

Abstract: A method including: (a) selectively reacting a first sugar in a mixture which includes at least one second sugar to form a product mixture comprising a product of said first sugar; (b) separating said product of said first sugar from said product mixture; and (c) separating at least one of said at least one second sugar from said product mixture.
Abstract: A method comprising: (a) providing a lignocellulosic substrate; (b) contacting said lignocellulosic substrate with an extractant comprising a water-soluble organic solvent to form an extracted substrate and a miscella; (c) removing miscella from said extracted substrate; and (d) hydrolyzing said extracted substrate using a chemically catalyzed process.

Abstract: A viscous fluid comprising 2% wt to 25% wt water, at least 75% wt carbohydrate (calculated by 100×[carbohydrate/(carbohydrate weight+water weight)]), between 0% wt and 25% wt of a second organic solvent and between 10% wt and 55% wt HCl (calculated by 100×[HCl weight/HCl weight+water weight]), which second organic solvent is characterized by at least one of: (a2) having a polarity related component of Hoy's cohesion parameter between 0 and 15 MPa1/2; (b2) having a Hydrogen bonding related component of Hoy's cohesion parameter between 0 and 20 MPa1/2; and (c2) having a solubility in water of less than 15% and forming a heterogeneous azeotrope with water, wherein the weight/weight ratio of said second organic solvent to water is in the range of between 50 and 0.02, and wherein the solubility of water in said organic solvent is less than 20%.
