Abstract:
A method of preparing a lignocellulosic composite comprising combining one or more lignocellulosic materials with a liquid curative, followed by the addition of one or more dry protein sources, forming the composition into a composite structure and then curing the composite structure.
Abstract:
The present invention provides for a method of producing a creped paper and the crepe paper products made using this method. The method includes treating the surface of a crepe fiber web and/or surface of a Yankee drum dryer or cylinder with compositions containing a combination of hydrophobes and surfactants and wherein these compositions have been subjected to physical treatments to reduce the mean particle size to about 1 micron (μm) or less.
Abstract:
A process for enhancing mining processes and in particular to the combination of anionic grinding aids with cationic flocculating agents, an anionic flocculant containing sulphonated and/or carboxylated groups, a terpolymer and combinations thereof at the flocculating stage in mineral ore processing applications, thereby enhancing the effectiveness of mining processes particularly in the grinding and flocculating of the mineral ore slurry.
Abstract:
A method of treating a cellulosic slurry to improve drainage is disclosed; the method comprises adding a surfactant based brown stock wash aid to a cellulosic furnish in an amount of from 0.5 to 1 lbs per ton and adding a synthetic polymer papermachine drainage or strength aid to the furnish in an amount of from 0.1 to 10 lbs per ton, allowing the furnish to drain and forming a paper product.
Abstract:
A method is provided for the use of a process additive system to improve the separation of oil from a process stream (whole stillage, thin stillage, or syrup) generated as a byproduct in grain to ethanol production.
Abstract:
A method of reducing contaminants in a pulp or papermaking process includes the steps of: providing a lignocellulosic pulp comprising lignocellulosic fibers and at least one hydrophobic contaminant; providing a cationic polymer; providing a cleaning blend comprising a vegetable oil alkyl ester and at least one surfactant; and applying the cationic polymer and the cleaning blend to the lignocellulosic pulp to reduce a content of the at least one hydrophobic contaminant in the pulp or papermaking process.
Abstract:
A heat-sensitive recording composition and recording material. The recording material comprising a substrate, wherein a heat-sensitive composition comprising color formers, color developers and a sensitizer comprising a combination of ortho-toluenesulfonamide and para-toluenesulfonamide (OPTSA) is deposited onto the surface of the substrate.
Abstract:
A method of increasing chemical efficiency of chemical additives in a papermaking system includes the steps of providing thick stock pulp comprising soluble lignin, process water, and at least about 2% by weight of cellulosic fiber based on total weight of thick stock pulp, and adding at least one organic polymer to the thick stock pulp to reduce the amount of soluble lignin therein. The organic polymer is chosen from cationic polymers, non-ionic polymers and combinations thereof.
Abstract:
Compositions and methods are provided for the recovery of minerals from mineral suspension, such as lime generated in Kraft pulping processes. More particularly, the composition comprises polyalkoxylate co-polymers, alkyleneamine alkoxylates, and optionally anionic surfactants, that when added to mineral dewatering process, aids in the recovery of the mineral.
Abstract:
This disclosure provides a method of improving gold recovery in a cyanide leaching circuit comprising a gold ore slurry. The method includes the step of providing a gold recovery additive chosen from polyacrylic acid, copolymers of acrylic acid and a sulfonated co-monomer, and combinations thereof, wherein the additive has a weight average molecular weight of from about 500 to about 10,000 g/mol. The method also includes the step of combining the gold recovery additive with the gold ore slurry in the cyanide leaching circuit, wherein the gold recovery additive is present in an amount of from about 10 to about 1000 g per ton of dry gold ore to improve the recovery of gold from the gold ore slurry.
