20090011474 | Process for producing sugars from cellulosic biomass - A process for increasing production of sugars from cellulose in a plant biomass using ammonia after swelling of the biomass with water and enzymatic hydrolysis is described. The sugars are preferably fermented to an alcohol, particularly ethanol as a fuel for vehicles. | 01-08-2009 |
20090042259 | Process for enzymatically converting a plant biomass - The present invention describes a process for at least a 90% conversion of a plant biomass preferably by a reduction of the units of cellulase needed and by using a xylanase which acts synergistically with the cellulase to improve the yield of xylose and glucose as sugars. The process enables greater conversion of a lignocellulosic plant biomass to glucose and xylose for use as animal feeds and as fermentation as medium for producing ethanol. | 02-12-2009 |
20090053771 | Process for making fuels and chemicals from AFEX-treated whole grain or whole plants - A process for hydrolyzing whole grain or whole plant biomass after an Ammonia Fiber Explosion (AFEX) process step is described. The process preferably uses a biomass that is hydrolyzed using a different combination of enzymes (amylase, cellulase and hemicellulase) to sugars for fermentation to produce ethanol. Harvesting the whole plant inclusive of grains and stalk for ethanol bio-processing is an economical route for future biorefineries. In addition to sugars, various value-added products like proteins and oil can be co-generated. | 02-26-2009 |
20090093027 | Process for producing sugars and ethanol using corn stillage - A process for producing sugars from lignocellulosic materials such as corn stover by the addition of corn stillage as a carbon source is disclosed. The sugars are formed by treating the combination of the corn stillage and the lignocellulosic materials with hydrolytic enzymes. The sugars can be fermented to ethanol, and the process improves ethanol production economies with an increased sugar yield from the lignocellulosic materials. | 04-09-2009 |
20090318670 | Separation of Proteins from Grasses Integrated with Ammonia Fiber Explosion (AFEX) Pretreatment and Cellulose Hydrolysis - A process for extracting an aqueous ammonium hydroxide solution from a plant biomass after an Ammonia Fiber Explosion (AFEX) process step, is described. The proteins can be separated before or after a hydrolysis of sugar precursors (carbohydrates) from the biomass to produce sugars for fermentation to produce ethanol. The proteins are useful as animal feeds because of their amino acid food values. | 12-24-2009 |
20130217073 | DIGESTIBLE LIGNOCELLULOSIC BIOMASS AND EXTRACTIVES AND METHODS FOR PRODUCING SAME - The invention relates to methods for treating lignocellulosic biomass to obtain useful products therefrom. | 08-22-2013 |
20130244293 | FRACTIONATED EXTRACTIVE PRODUCTS FROM PLANT BIOMASS AND METHODS OF MAKING AND USING SAME - A method is provided comprising converting at least a portion of native cellulose I | 09-19-2013 |
20140038243 | METHODS FOR PRETREATING BIOMASS - A method for treating biomass is provided, which includes, in a reactor, allowing gaseous ammonia to condense on the biomass and react with water present in the biomass to produce pretreated biomass, wherein reactivity of polysaccharides in the biomass is increased during subsequent biological conversion as compared to polysaccharides in biomass which has not been pretreated. A method for treating biomass with a liquid ammonia and recovering the liquid ammonia is also provided. Related systems which include a biochemical or biofuel production facility are disclosed. | 02-06-2014 |
