Patent number: 9624449Abstract: Non-food plant biomass is subjected hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C. without addition of reagents, to yield an aqueous extract containing hemicellulosic components and a lignocellulosic residue. The process leaves the lignocellulose substantially intact, but with the hemicellulosic content largely removed. The separated aqueous extract or liquor is concentrated and purified, and long-chain sugars are reduced into monomer saccharides. The lignocellulosic residue may be further processed, to yield a useful fibrous material that is highly resistant to sorption of water. This material may be used for composite materials that resist water degradation, or may be used to produce a higher thermal-yield, water-resistant fuel, or may be used as bioconversion feedstock for producing high-value, lignocellulosic derivatives.Type: GrantFiled: December 19, 2013Date of Patent: April 18, 2017Assignee: Applied Biorefinery Sciences LLC.Inventors: Joel R Howard, Thomas E Amidon, Christopher D Wood

Patent number: 8618280Abstract: Non-food plant biomass is subjected to hot-water extraction in a pressurized vessel at an elevated temperature up to about 250° C. and at a pH below about 7.0, to yield an aqueous extract containing hemicellulosic components, other wood-derived compounds, and a lignocellulosic residue. The separated aqueous extract or liquor is purified and concentrated through a multi-step process producing fermentable sugars. At each stage, inhibitory chemicals such as acetic acid, lignin, and furfural are separated and eventually recovered as commercial chemicals. The lignocellulosic residue may be further processed, as a material with enhanced resistance to sorption of water, for manufacture of improved pulp and paper, construction materials, pellet fuel, and/or other useful products.Type: GrantFiled: August 5, 2010Date of Patent: December 31, 2013Assignee: Applied Biorefinery Sciences LLCInventors: Joel R.

Publication number: 20110073264Abstract: The method of the present invention is directed towards a method to increase the pulp yield of a lignocellulosic material, or increasing pulp bulk and/or pulp viscosity. This method comprises the following steps; preparing a lignocellulosic material, contacting the lignocellulosic material in a vessel with hot water or steam for a predetermined time, producing acetic acid from the reaction of the hot water or steam and the lignocellulosic material, lowering the pH to less than about 4, removing lignocellulosic material extracts including a large percentage of hemicellulose, acetic acid and metal ions, exposing contacted lignocellulosic material to pulping chemicals in a pulping reactor, forming a contacted lignocellulosic material pulp with a kappa number below about 19 after about 90 minutes of contact with the pulping chemicals, exposing the contacted lignocellulosic material pulp to whitening agents, and producing a whitened hot water contacted lignocellulosic material pulp.Type: ApplicationFiled: August 12, 2010Publication date: March 31, 2011Applicant: The Research Foundation of State University of New YorkInventors: Shijie Liu, Gangesh Mishra, Thomas E.

Patent number: 6017415Abstract: A method wherein waste cellulosic material is used as an alternative fiber source during chemical pulping to replace a fraction of the wood chips. The waste cellulosic material is fed to the digester along with wood chips. The waste cellulosic material need not be repulped or slurried prior to digestion. The wood chips may be any species of hardwood or softwood. Normal chemical pulping charges, temperatures and cooking times applied in the case of 100% wood chip pulping may be used for the co-pulping of waste cellulosic material and wood chips. Thereafter, the pulp is processed as usual for chemical pulping, including the steps of blowing the digester, washing and thickening the brown stock, and bleaching the brown stock under the normal conditions used for the component co-pulped with the waste cellulosic material. Further screening or cleaning steps may be required to remove debris from waste cellulosic material.Type: GrantFiled: September 5, 1997Date of Patent: January 25, 2000Assignee: International Paper CompanyInventors: Richard B.
