20140374040 | PROCESS FOR THE PRODUCTION OF AN INTERMEDIATE PRODUCT INTENDED FOR THE PRODUCTION OF ETHANOL AND FOR THE PRODUCTION OF LIGNIN - A process for producing from a lignocellulosic raw material of (i) an intermediate product that is intended for the production of ethanol, containing polysaccharides, cellulose and hemicelluloses, and (ii) a product containing lignin in an aqueous solution without sulfur residue, this lignin could be precipitated. The process includes a step of pulping the raw material in an extruder at a temperature of between 60° C. and 180° C. and in the presence of a quantity of water that represents between 200% and 450% of the mass of said raw material and in the presence of a strong base at a concentration of between 0.5% and 4% relative to the volume of water. | 12-25-2014 |
20140303278 | PROCESS FOR PREPARING A POLYMER/BIOLOGICAL ENTITIES ALLOY - The present invention relates to a process for preparing a polymer/biological entities alloy, comprising a step of mixing a polymer and biological entities that degrade it, during a heat treatment, said heat treatment being performed at a temperature T above room temperature and said biological entities being resistant to said temperature T, characterized in that said biological entities are chosen from enzymes that degrade said polymer and microorganisms that degrade said polymer. | 10-09-2014 |
20130023013 | METHOD FOR OBTAINING A FERMENTABLE PRODUCT FROM POLLUTED LIGNO-CELLULOSIC BIOMASS - A method for obtaining a fermentable product intended for the production of metabolites by fermentation, includes the following steps: a) detoxification of a polluted ligno-cellulosic raw material including at least one polluting component; solid-liquid extraction in order to extract the polluting component(s) from the ligno-cellulosic raw material by solubilisation using at least one solvent; recovery of the cleaned ligno-cellulosic raw material; b) pre-treatment of the cleaned ligno-cellulosic raw material by defibration; c) enzymatic hydrolysis of the pre-treated ligno-cellulosic raw material in the presence of cellulose, and obtaining a fermentable product; d) optional purification of the resulting fermentable product. The use of the resulting fermentable product for producing metabolites by fermentation, as well as to a specific method for producing ethanol from the fermentable product are also described. | 01-24-2013 |

Also described is a process for manufacturing functionalized hydroxycarboxylic acid oligomers including at least one stage for polycondensation of a hydroxycarboxylic acid and a functional agent, as well as functionalized hydroxycarboxylic acid oligomers that can be obtained and the adhesive compositions that include them. | 08-30-2012 |
20120209018 | METHOD FOR EXTRACTING UNSAPONIFIABLES FROM RENEWABLE RAW MATERIALS - A method for extracting an unsaponifiable fraction from a renewable raw material selected among oilfruits, oleaginous seeds, oleoproteaginous seeds, seed husks, oil-yielding almonds, sprouts, stones and cuticles of fruits, high-fat raw materials from animals, algae, fungus or yeast, includes the following steps: a) dehydrating and packaging the renewable raw material, not resulting in any extraction of the fat; b) reactive crushing of the fatty packaged raw material in the presence of a light alcohol and a catalyst; c) evaporating the light alcohol; d) concentrating the liquid phase such as to obtain a concentrate including the unsaponifiable fraction diluted in fatty acid alkyl esters; e) saponifying the unsaponifiable concentrate; f) extracting the unsaponifiable fraction from the saponified mixture. The use of an unsaponifiable fraction or co-products obtained by implementing the method for preparing a composition such as a cosmetic, drug, food, or food additive or supplement is also described. | 08-16-2012 |
20120101192 | COMPOSITION, METHOD FOR PREPARING SAME, AND USE THEREOF FOR IMPROVING THE FLUIDITY AND TEMPERATURE RESISTANCE OF COMPOSITE MATERIALS - A composition or master batch including at least one functionalized polyglycerol, at least one biopolymer, and a meal obtained from plant carbon, and its use for improving the fluidity in the molten state and the heat resistance of composite materials, in particular composites based on biopolymers that are optionally loaded with plant meal. Also, a process for the preparation of this composition, as well as the materials that integrate it. | 04-26-2012 |
20110236945 | USE OF RECYCLED COTTON FOR PRODUCING ETHANOL, AND PRODUCTION METHOD - Recycled textile cotton is used for producing ethanol by the execution of a process that includes a) a stage of pretreatment of textile cotton, optionally with grinding of textile cotton, pretreatment of textile cotton that may or may not be ground by pulping | 09-29-2011 |
20110236944 | METHOD FOR PRODUCING INTERMEDIATE MATERIAL INTENDED FOR ETHANOL PRODUCTION, AND RESULTING INTERMEDIATE MATERIAL - A process for the production of an intermediate product from a lignocellulosic raw material that is intended for the production of ethanol, which process includes pulping the raw material in an extruder at a temperature of between 60° C. and 180° C., in the presence of a quantity of water that represents between 200% and 450% of the mass of the raw material and preferably in the presence of a strong acid or a strong base that is weakly concentrated. An intermediate product can be obtained by this process for producing ethanol. | 09-29-2011 |
