20090020243 | Use of Cyclodextrins for Reducing Deposits During Paper Production - The present invention relates to a method for preventing or reducing deposits in pulp and paper making processes by including a cyclodextrin during or after pulp formation in an amount effective for preventing or reducing the deposits. Optionally the cyclodextrin comprising the deposit is subsequently separated from the pulp. | 01-22-2009 |
20090065159 | CHEMICAL PULP TREATMENT COMPOSITIONS AND METHODS - The present invention relates to compositions and methods for treating pitch problems in chemical pulp by treating chemical pulp process water with a combination of a lipase and a peroxide source. The present invention also relates to compositions and methods for treating pitch problems in chemical pulp by treating chemical pulp process water with a lipase, a peroxide source and organic acid(s). | 03-12-2009 |
20120193047 | METHODS FOR REDUCING CHLORINE DIOXIDE ASSOCIATED CORROSION - Methods for inhibiting chlorine dioxide associated corrosion in industrial equipment by treating industrial equipment (e.g., pipes, washers and other metallic, e.g., stainless steel surfaces) or process streams in contact with industrial equipment with one or more haloperoxidases, preferably, a chloroperoxidase, in an amount effective to reduce chlorine dioxide associated corrosion. | 08-02-2012 |
20130224802 | Methods of Hydrolyzing Oligomers in Hemicellulosic Liquor - The present invention relates to methods of degrading or converting biomass material enriched with hemicellulosic material into fermentable sugars. | 08-29-2013 |
20130337509 | Processes for Enzymatic Refining of Pretreated Cellulosic Material for Saccharification - The present invention relates to processes for processes for enzymatic refining of a pretreated cellulosic material for saccharification. | 12-19-2013 |
20140147895 | Processes for Pretreating Cellulosic Material and Improving Hydrolysis Thereof - The present invention relates to processes for pre-treating cellulosic material and processes for improving hydrolysis thereof. In particular, cellulosic material such as woody biomass is contacted with one or more enzymes in a re-pulping step. The cellulosic material is then contacted with one or more enzymes to improve hydrolysis of the cellulosic material. The hydrolysis is also enzymatically enhanced by use of an amylase and/or mannanase. | 05-29-2014 |
20140206046 | Methods of Hydrolyzing and Fermenting Cellulosic Material - Described herein are improved methods of degrading or converting cellulosic material into fermentable sugars using dithionite. Also described are improved methods of fermentation in the presence of dithionite. | 07-24-2014 |
20140262093 | Properties of Paper Materials - The use of GH61 polypeptides in the treatment of pulp, for improving tear strength and/or tensile strength of the corresponding paper materials, such as paper, linerboard, corrugated paperboard, tissue, towels, corrugated containers and boxes. | 09-18-2014 |
