| 20080227161 | METHODS FOR PRODUCING A HYDROLYSATE AND ETHANOL FROM LIGNOCELLULOSIC MATERIALS - A method for producing a hydrolysate from lignocellulosic materials generally includes fiberizing the lignocellulosic materials, separating the lignocellulosic materials into at least a first portion and a second portion, wherein at least the first portion includes lignin, treating the first portion to deactivate at least a portion of the lignin in the first portion, re-combining the first and second portions after treating the first portion, and hydrolyzing the lignocellulosic materials with enzymes to produce a hydrolysate. | 09-18-2008 |
| 20080241536 | Method for processing cellulose in ionic liquids and fibers therefrom - The present application is directed to a process of dissolving cellulose in an ionic liquid, regenerating the fibers and forming a nonwoven web. In particular it is directed to fibers produced from cellulose dissolved in ionic solvents and extruded by the meltblowing process. Bonded nonwoven webs can be obtained in the process. | 10-02-2008 |
| 20090084509 | Dissolution of Cellulose in Mixed Solvent Systems - A method for dissolving cellulose in which the cellulose based raw material is admixed with a mixture of a protic intercrystalline swelling agent and an ionic liquid at a temperature of 25° C. to 180° C. for a time sufficient to dissolve the cellulose based raw material. The molar ratio of protic intercyrstalline swelling agent to ionic liquid may be 0.05 to 1.5 moles of protic intercrystalline swelling agent to 1 mole of ionic liquid. | 04-02-2009 |
| 20090088564 | Dissolution of Cellulose in Mixed Solvent Systems - 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° C. to 180° 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. | 04-02-2009 |
| 20100152428 | LOW Tg LIGNIN MIXED ESTERS - The disclosure includes lignin mixed esters comprising first ester groups and second ester groups wherein the number of carbon atoms in the first ester group differs from the number of carbon atoms in the second ester group by 3 or more and processes of making the same. The unique thermal glass transition temperature properties of such lignin mixed esters are described. | 06-17-2010 |
| 20100163195 | High-Yield Paper and Methods of Making Same - 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 a surface layer on the sheet including nPCC pigment. | 07-01-2010 |
| 20100163196 | High-Yield Paper and Methods of Making Same - 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. | 07-01-2010 |
| 20100163198 | High-Yield Paper and Methods of Making Same - A method of making a high-yield paper sheet generally includes blending a pulp mixture including at least about 50 weight percent mechanical pulp, making an uncoated paper sheet from the pulp mixture, applying a surface layer to the paper sheet, the surface layer including nPCC, and drying the sheet, wherein the basis weight of the dried sheet is in the range of about 24 to about 60 pounds. | 07-01-2010 |
| 20100163199 | READILY DEFIBERED PULP PRODUCT - A wet-laid wood pulp product containing cellulose pulp fibers and elongate precipitated calcium carbonate having a diameter of 0.015 to 0.6 microns at its maximum diameter and a length of 1 to 10 microns and the calcium carbonate being incorporated within the sheet and a method for making the product. | 07-01-2010 |
| 20110047865 | ARTIFICIAL FIRE LOG - 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. | 03-03-2011 |
| 20110054154 | LIGNOTHERMOPLASTIC - 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. | 03-03-2011 |
