Paper Making And Fiber Liberation > Processes Of Chemical Liberation, Recovery Or Purification Of Natural Cellulose Or Fibrous Material > Treatment With Particular Chemical > Organic OrganicOrganic patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.07/05/07 - 20070151683 - Process for preparing mechanical pulp The invention relates to a method for the pre-treatment of chips, which can be used to reduce the specific energy consumption of mechanical pulp and to improve the technical properties of the fibres. In the treatment, chips in a liquid phase are brought into contact with an enzyme preparation containing ... 04/12/07 - 20070079944 - Product and processes from an integrated forest biorefinery An omnibus process of pulping and bleaching lignocellulosic materials in which a charge of a lignocellulosic material is biopulped and/or water extracted prior to pulping and bleaching. The lignocellulosic material may be mechanically pulped and bleached in the presence of an enzyme that breaks lignin-carbohydrate complexes. The aqueous extract in ... 03/22/07 - 20070062654 - Treatment of wood chips using enzymes A method of treating wood chips or saw dust with an enzyme formulation, prior to refining, in order to reduce the total extractives content of the wood chips or sawdust and to modify the wood structure is described herein. The wood chips or sawdust are treated with one or more ... 02/15/07 - 20070034345 - Process for organosolv pulping and use of a gamma lactone in a solvent for organosolv pulping The invention further provides the use of a compound according to general molecular formula (1) in a solvent for organosolv pulping. ... 02/08/07 - 20070029059 - Enzymatic opacifying composition for paper, pulp or paperboard, processes using same and pulp, paper or paperboard produced therefrom An organic agent for enhancing opacity in paper, paperboard or pulp comprises a hydrolase or an oxido-reductase; this enzymatic opacifying agent overcomes drawbacks associated with traditional organic and inorganic opacifying agents but also serves to provide increased strength and reduced porosity in paper and paperboard. ... 07/06/06 - 20060144533 - Method for the production of improved pulp Compositions and method for improving properties of pulp produced or reducing the digester cycle time in alkaline chemical pulping processes in which an effective amount of at least one selected phosphonate or carboxylate compound or mixtures thereof is admixed with the alkaline aqueous mixture in the digester of the chemical ... 03/23/06 - 20060060316 - Biopulp for non-woody fiber plants and biopulping method thereof A biopulp for a non-woody fiber plant is provided. The biopulp includes a non-woody fiber plant and a suspension of a microorganism. The non-woody fiber plant and the microorganism suspension are mixed and fermentatively cultured for preparing said biopulp. ... 02/02/06 - 20060021724 - Process for bio-bleaching of kraft pulp using bacterial consortia The present invention relates to an environment friendly, safe, and efficient four-step method of bio-bleaching Kraft pulp using bacterial strains of accession no. MTCC 5096, MTCC 5094, MTCC 5095, and MTCC 5098, a microbial consortium comprising a synergistic mixture of ligninolytic bacterial isolates of accession no. MTCC 5094, MTCC 5095, ... 12/22/05 - 20050279469 - Retention aid additives for paper making A selective immobilized enzyme bioadditive retention aid comprising an enzyme chemically bound to a particulate inorganic support, said enzyme having a binding site selectively linkable to an organic polymeric fibrous material component of a pulp. The invention provides an improved process of paper manufacture and the novel paper making additives ... 12/08/05 - 20050269049 - Light-stable and process-stable lignocellulosic materials and their production A novel method for the production of light-stable and process-stable lignocellulosic materials, in particular, the production of mechanical wood pulps with much improved light and process stability is described, as well as the resulting pulps of improved light and process stability and papers containing such pulps. The novel method involves ... 11/24/05 - 20050257905 - Process and composition for preparing a lignocellulose-based product, and the product obtained by the process A process for the manufacture of a lignocellulose product, the process comprising the step of mixing in a reaction medium (i) a phenolic polymer being substituted with a phenolic hydroxy group; (ii) a lignocellulose containing material having immobilized to a cellulosic fraction thereof a fusion polypeptide, the fusion polypeptide including ... 11/03/05 - 20050241785 - Method of producing mechanical pulp and the mechanical pulp thus produced A method of producing mechanical pulp, comprising impregnation of fiber material with an enzyme-containing aqueous liquid prior to defibration and refining of the fiber material to produce a mechanical pulp. According to the invention, said enzyme-containing aqueous liquid is a pectinase-containing aqueous liquid. The invention is also related to the ... 10/06/05 - 20050217813 - Methods to enhance brightness of pulp and optimize use of bleaching chemicals Mechanical or Chemical pulp is treated with about 0.01 weight % to about 5 weight % of a Mixture. The Mixture is water; diethylenetriaminepentakis(methyl)phosphonic acid or its known salts; polyacrylic acid or its known salts; and optionally one or more inert compounds. This Mixture acts to either maintain the brightness ... 07/14/05 - 20050150619 - Xylanase treatment of chemical pulp The present invention discloses methods of bleaching chemical pulp that use xylanase enzymes after chemical bleaching. The method comprises the steps of carrying out a chlorine dioxide stage to produce a partially bleached pulp, treating the partially bleached pulp with a xylanase enzyme, optionally in the presence of oxygen and ... ### FreshPatents.com Support |
