Methods of producing clean (e.g., low sulfur and metal ion content, and free of fermentation inhibitors) sugar and lignin-rich streams, and downstream conversion products, from lignocellulosic biomass, may include obtaining non-chemically pretreated, milled lignocellulosic biomass, reacting the milled lignocellulosic biomass with an enzymatic agent to produce a slurry that includes converted monomeric lignocellulosic sugars and lignin-rich residuals, and separating the slurry into a sugar stream that includes the converted monomeric lignocellulosic sugars and a lignin-rich stream that includes the lignin-rich residuals. The sugar stream, not including water, includes at least 75% monomeric lignocellulosic sugar, less than 0.20% sulfur, and less than 3.0% metal ion content, and the lignin-rich stream includes at least 35% lignin and less than 0.50% sulfur. Some methods include producing fermentation products such as alcohols and/or organic acids from the sugar stream, and/or use of the lignin residuals in fuels.

Esterified cellulose pulp compositions produced in high yield from commercially available wood pulp sources, methods for making the esterified cellulose pulp compositions, and articles prepared from the esterified cellulose pulp compositions.

Esterified cellulose pulp compositions and related methods

A resin for OSB comprising an aqueous resole reaction product of phenol, formaldehyde, alkaline metal hydroxide or carbonate, urea and a degraded lignin polymer having 35-65% solids, a pH of 8-13 and a viscosity 50-1000 centipoises. The phenol and formaldehyde are present in a molar ratio of 1.5 to 3.4 moles formaldehyde to 1 mole phenol and are 40 to 85% of the total solids added to the mixture. In one embodiment they are 50 to 75% of the total solids added to the mixture. The alkaline metal hydroxide or carbonate are 5 to 20% of the total solids added to the mixture. Urea is 5 to 35% of the total solids added to the mixture. The degraded lignin is 5 to 20% of the total solids added to the mixture. A method for making the resin and a product using the resin.

Utilization of kraft lignin in phenol/formaldehyde bonding resins for OSB

A thermoplastic material made from lignin, polyol and a melting point reducer where the melting point reducer is miscible in the specific polyol employed and where the lignin, polyol and melting point reducer are all miscible when in their melted state.

Lignothermoplastic

Artificial fire logs made from non-petrochemical based, renewable materials are described. These artificial fire logs perform substantially equivalent to existing commercial fire logs. The artificial fire logs are made from cellulosic materials, a lignin containing composition and a non-petroleum based wax where the lignin containing composition comprises lignin and 1,3-propanediol derived from a renewable resource.

The barrier properties of a water soluble gas barrier material are improved if the material is blended with a nanoparticle calcium carbonate having a size of from 10 to 250 nanometers. The barrier material is on a substrate to provide a substrate with gas barrier properties. A layer of heat sealable material may be applied to the exposed surface of the barrier material. A method for making the barrier coated substrate is disclosed.

Barrier material

A high-yield paper sheet generally includes at least about 50 weight percent mechanical pulp, wherein the basis weight of the sheet is in the range of about 24 to about 60 pounds, and wherein the porosity of the sheet is in the range of about 40 to about 100 Sheffield porosity.

High-yield paper and methods of making same

A method for dissolving cellulose in which the cellulose based raw material is admixed with a mixture of a dipolar aprotic intercrystalline swelling agent and an ionic liquid at a temperature of 25&#xb0; C. to 180&#xb0; C. for a time sufficient to dissolve the cellulose based raw material. The molar ratio of dipolar aprotic intercrystalline swelling agent to ionic liquid is 0.05 to 1.5 moles of dipolar aprotic intercrystalline swelling agent to 1 mole of ionic liquid. Dipolar aprotic intercrystalline swelling agents do not include imidazole based agents or amine based agents.

Dissolution of cellulose in mixed solvent systems

Systems for attaching a plurality of wood products are provided. In a first type of system, a first wood product has a first chemical compound applied to a surface of the first wood product. A second wood product has a second chemical compound applied to a surface of the second wood product. An adduct is formed when the first chemical compound contacts the second chemical compound wherein the first wood product becomes adhered to the second wood product. In a second type of system, a pressure sensitive and/or anaerobic adhesive is placed on at least one of the wood products prior to assembly. The compounds/adhesives have an open assembly time greater than or approximately equal to 24 hours.

Method of making a barrier material

Methods for esterifying hydroxyl groups in cellulose, hemicellulose, and lignin in wood are described, wherein the wood is chosen from loblolly, slash, shortleaf, longleaf or radiata pines. Methods can include solvent drying techniques and heating provided by electromagnetic radiation, such as microwave, and radiofrequency. Products made from the methods are described that have greater decay resistance and dimensional stability as compared with non-esterified wood products.
