Title: Method to separate lignin-rich solid phase from acidic biomass suspension at an acidic pH

Abstract

A method of separating a lignin-rich solid phase from a solution suspension, by pretreating a lignocellulosic biomass with a pretreatment fluid having remove soluble components, colloidal material and primarily lignin containing particles; separating the pretreated lignocellulosic biomass from the pretreatment fluid with soluble components, colloidal material and primarily lignin containing particles; flocculating the separated pretreatment fluid with soluble components, colloidal material and primarily lignin containing particles using polyethylene oxide (i.e., PEO) or cationic Poly acrylamide (i.e., CPAM) as a flocculating agent; and filtering the flocculated separated pretreatment fluid with soluble components, colloidal material and primarily lignin containing particles to remove agglomerates.

Methods of recovering lignin and other products from biomass

Patent Nguyen, Quang A.; Wendt, Lynn M.

Methods of recovering lignin products and other products from biomass. The method comprises adding a chemical agent to a stored biomass comprising lignin to form a chemically-treated biomass. The chemical agent comprises an acid, a base, an inorganic salt, or a combination of the inorganic salt and one of the acid or the base. The chemically-treated biomass is stored under anaerobic conditions. Lignin products, such as high molecular weight lignin, medium molecular weight lignin, or low molecular weight lignin, are recovered from the chemically-treated biomass. Additional methods of recovering lignin products and other products from biomass are disclosed.

Method for improving separation of carbohydrates from wood pulping and wood or biomass hydrolysis liquors

Patent Griffith, William Louis; Compere, Alicia Lucille; Leitten, Jr., Carl Frederick

A method for separating carbohydrates from pulping liquors includes the steps of providing a wood pulping or wood or biomass hydrolysis pulping liquor having lignin therein, and mixing the liquor with an acid or a gas which forms an acid upon contact with water to initiate precipitation of carbohydrate to begin formation of a precipitate. During precipitation, at least one long chain carboxylated carbohydrate and at least one cationic polymer, such as a polyamine or polyimine are added, wherein the precipitate aggregates into larger precipitate structures. Carbohydrate gel precipitates are then selectively removed from the larger precipitate structures. The methodmore » « less

Method of separating lignocellulosic material into lignin, cellulose and dissolved sugars

Patent Black, Stuart K [Denver, CO]; Hames, Bonnie R [Westminster, CO]; Myers, Michele D [Dacono, CO]

A method for separating lignocellulosic material into (a) lignin, (b) cellulose, and (c) hemicellulose and dissolved sugars. Wood or herbaceous biomass is digested at elevated temperature in a single-phase mixture of alcohol, water and a water-immiscible organic solvent (e.g., a ketone). After digestion, the amount of water or organic solvent is adjusted so that there is phase separation. The lignin is present in the organic solvent, the cellulose is present in a solid pulp phase, and the aqueous phase includes hemicellulose and any dissolved sugars.

Methods for separating non-fibrous solids from liquids using a double-roller

Patent Baxter, Larry; Davis, Nathan

A method for separating solids from liquids is disclosed. A double-roller system is provided. A process fluid is provided to the double-roller system. The process fluid comprises a suspended solid and a process liquid. The suspended solid comprises non-fibrous solid particles. A portion of the process fluid is compressed through the double-roller system to produce a compressed portion of the suspended solid. A product stream and a dilute fluid stream are separated. The product stream comprises a compressed portion of the suspended solid and a first portion of the process liquid. The dilute fluid stream comprises a second portion ofmore » « less
