| 20080213849 | Ethanol production from solid citrus processing waste - Method for producing ethanol from solid citrus waste by reducing the concentration of limonene in citrus waste to allow fermentation. In one embodiment ground solid citrus waste is partially hydrolyzed and pasteurized by heating using a jet cooker and then injected into a flash tank to remove limonene. The heated citrus waste is then cooled, hydrolyzed with enzymes and fermented to ethanol. The remaining solids and liquids may be processed further to yield other byproducts. More particularly, the solids may be dried and pressed for use in cattle feed and the liquids may be further fermented or processed to yield additional ethanol, acetate, galacturonic acid monomers and polymers, five carbon sugars and other products. | 09-04-2008 |
| 20090291482 | ETHANOL PRODUCTION FROM CITRUS WASTE THROUGH LIMONENE REDUCTION - The present invention relates to processes for producing ethanol from citrus waste wherein the level of fermentation-inhibiting compounds found in citrus waste or the complex polysaccharide or sugars derived therefrom is reduced using a pre-fermentation treatment step to lower the level of fermentation-inhibiting compounds to the fermentation feedstock. | 11-26-2009 |

| 20090068715 | METHOD OF PRODUCING BIO-ETHANOL - A method of producing ethanol, which comprises of starch obtained from continuously cultivated unicellular green algae strains which reproduce through a single cell clone cultivation method that cyclically produces starch extra-cellularly. Only the starch is recovered and goes through a saccharification and fermentation process for the production of ethanol. The algae are left for continual reprocessing. The obtained starch is then saccharified and fermented to produce ethanol. This production method is available and feasible in any part the world, from tropical areas to high latitude areas because it is controlled not by natural climatic conditions but in an environment that is monitored and controlled by humans. The continuous production process from these | 03-12-2009 |
| 20090291481 | REMOVAL OF FERMENTATION INHIBITING COMPOUNDS FROM CITRUS WASTE USING SOLVENT EXTRACTION AND PRODUCTION OF ETHANOL FROM CITRUS WASTE - The present invention relates to novel processes for producing ethanol from citrus waste using suitable solvent extractions to reduce the presence of fermentation inhibiting compounds, such as limonene, from citrus waste. The extraction can be performed before or after the polysaccharides present in aqueous mixtures comprising citrus waste are converted into fermentable sugars. | 11-26-2009 |
| 20090325253 | METHODS AND SYSTEMS FOR PRODUCTION OF BIOFUELS AND BIOENERGY PRODUCTS FROM SEWAGE SLUDGE, INCLUDING RECALCITRANT SLUDGE - The present invention provides methods and systems (SLUDFUEL system) for producing biofuel and bioenergy products using, as starting raw material, municipal, industrial, and/or farm sewage sludge, including recalcitrant sludge containing high concentrations of heavy metals, and produced after waste treatment. In accordance with the invention, municipal, industrial, and farm sewage sludge, including recalcitrant sludge, can serve as a carbon source to support the metabolism of synthetic microorganisms to produce biofuels and bioenergy products. | 12-31-2009 |
| 20100317079 | SILAGE WASTE RECOVERY PROCESS, FACILITY, SYSTEM, AND PRODUCT - A silo of conventional construction is provided with a collection pan at its bottom to collect effluent. The effluent can be stored and/or processed. Processing can include separation of water to concentrate the effluent. The effluent can contain fermentation product, such as alcohol, generated within the silo prior to collection, and it can also be fermented after collection. Processed effluent can be handled safely without risk of contamination to ground water at the silo site. | 12-16-2010 |
| 20110065159 | BIOMASS HYDROLYSIS - High-yielding method for chemical hydrolysis of lignocellulose into monosaccharides. The process of the invention can additionally be applied to cellulose, xylan and related biomass polysaccharides, such as galactan, mannan, or arabinan. The method is employed for hydrolysis of a biomass polysaccharide substrate. The process is carried out in an ionic liquid in which cellulose is soluble in the presence of catalytic acid at a temperature sufficiently high to initiate hydrolysis. Water is added to the reaction mixture after initiation of hydrolysis at a rate controlled to avoid precipitation yet avoid undesired sugar dehydration products such ad HMF. Hydrolysis product is useful as feedstock for fermentations including fermentation processes for ethanol, butanol and other fuels. | 03-17-2011 |

| 20130344557 | SYSTEMS AND METHODS FOR IMPROVING ETHANOL YIELD - Systems and methods for improving ethanol yield are provided. A feedstock is ground suitably fine for use in fermentation. The feedstock may include corn or any other suitable material. In some cases, the feedstock undergoes a fractionation prior to grinding. The ground feedstock may be slurried with water and enzymes to facilitate conversion of the starch in the feedstock to sugars. The slurry may be about 35% solids. After being slurried, an ethanologen may be added. Additionally, the pH of the slurry may be adjusted to between 4.2 and 5.2 to facilitate the priming A primer is added to the slurry. The primer may include any weak acid, and in some embodiments includes acetic acid. Acetic acid, when used as a primer, may be added at a concentration of between 1200 and 3600 parts per million.
