20140273131 | METHODS AND SYSTEMS FOR USE IN DEACTIVATING ORGANISMS USED IN BIOPRODUCT PRODUCTION PROCESSES - A method for deactivating organisms used in fermenting a biomass to produce one or more bioproducts (e.g., ethanol, etc.) generally includes an operation of conveying the organisms from a fermentation chamber to a distillation unit, and then an operation of effecting a positive six-log kill of the organisms in the distillation unit. A system for producing the one or more bioproducts, making use of the method, generally includes the fermentation chamber for holding the organisms during the fermentation operation, and the distillation unit configured to receive the fermented biomass, including the organisms, from the fermentation chamber. The distillation unit is operable to effect the positive six-log kill of the organisms in the distillation unit. In some applications of the method and system, the organisms are genetically modified organisms. | 09-18-2014 |
20120111321 | METHOD AND APPARATUS FOR TREATING A CELLULOSIC FEEDSTOCK - Methods and apparatus for treating, pre-treating, preparing and conveying a cellulosic feedstock, such as for ethanol production, are disclosed. More specifically, the invention relates to methods and apparatus for treating a cellulosic feedstock by mixing and heating the cellulosic feedstock and/or by moistening and heating the cellulosic feedstock. The invention also relates to a holding tank, and a method of utilizing the holding tank whereby bridging may be reduced or eliminated and may result in a product stream from autohydrolysis or hydrolysis having an improved yield. The invention further relates to methods and apparatus for obtaining and conveying a cellulosic feedstock, which may be used for the subsequent production of a fermentable sugar stream from the cellulose and hemicellulose in the cellulosic feedstock wherein the fermentable sugar stream may be used for subsequent ethanol production. The invention also relates to a method and apparatus for withdrawing one or more feedstock stream from a holding tank. | 05-10-2012 |
20120045545 | HIGH EFFICIENCY ETHANOL PROCESS AND HIGH PROTEIN FEED CO-PRODUCT - A process is disclosed for producing a feed co-product by ethanol fermentation of plant matter comprising starch and another polysaccharide selected from the group consisting of hemicellulose and cellulose. The process comprises: (i) carrying out a primary fermentation process, distilling the primary fermentation mixture to form a primary feed co-product derived from the fermentation of the primary fermentation mixture and a primary distillate product comprising ethanol and (ii) carrying out a secondary fermentation process and distilling the secondary fermentation mixture to form the modified feed co-product and a secondary distillate product comprising ethanol. | 02-23-2012 |
20120006320 | METHOD FOR PRODUCING ETHANOL AND CO-PRODUCTS FROM CELLULOSIC BIOMASS - The present invention generally relates to processes for production of ethanol from cellulosic biomass. The present invention also relates to production of various co-products of preparation of ethanol from cellulosic biomass. The present invention further relates to improvements in one or more aspects of preparation of ethanol from cellulosic biomass including, for example, improved methods for cleaning biomass feedstocks, improved acid impregnation, and improved steam treatment, or “steam explosion.” | 01-12-2012 |
20110271875 | Process for Recovery of Values from a Fermentation Mass Obtained in Producing Ethanol and Products Thereof - The present invention generally relates to processes for recovery of values from a fermentation mass obtained in producing ethanol. Further, the present invention relates to processes for the recovery of values from an inorganic- and lignin-containing mass. The present invention also relates to processes for the recovery of a fraction having enhanced silica content from a silica-containing mass. Still further, the present invention relates to processes for the recovery of crude ethanol from a fermentation mass. The present invention relates to various lignin-containing products and solutions and mineral-rich products. | 11-10-2011 |
20110262984 | METHOD FOR PRODUCING ETHANOL AND CO-PRODUCTS FROM CELLULOSIC BIOMASS - The present invention generally relates to processes for production of ethanol from cellulosic biomass. The present invention also relates to production of various co-products of preparation of ethanol from cellulosic biomass. The present invention further relates to improvements in one or more aspects of preparation of ethanol from cellulosic biomass including, for example, improved methods for cleaning biomass feedstocks, improved acid impregnation, and improved steam treatment, or “steam explosion.” | 10-27-2011 |
20110008489 | QUALITY AND VALUE OF CO-PRODUCTS OF THE ETHANOL PRODUCTION INDUSTRY - A process for improving the nutritional quality of a feed co-product, resulting from the fermentation of a grain, sugar beets, or sugar cane to produce ethanol. The process comprises combining water, a source of nitrogen, a source of phosphorus, a feed co-product comprising a cellulose and/or a hemi-cellulose, and a microbe to form a fluid fermentation mixture suitable for submerged fermentation, wherein the feed co-product is derived from the fermentation of a grain, sugar beet, or sugar cane to produce ethanol and wherein the microbe is a microbe capable of breaking down the cellulose and/or the hemi-cellulose to one or more sugars and then utilizing the sugars to proliferate; fermenting the fluid fermentation mixture such that the microbe converts at least a portion of the cellulose and/or the hemi-cellulose into at least one sugar and uses the sugar to proliferate thereby increasing the concentration of microbes in the fermentation mixture. | 01-13-2011 |
