摘要： Disclosed is an improvement in a conventional process for C5 and C6 sugar recovery from lignocellulosic biomass for fermentation to ethanol, which process including the conventional steps of pretreatment of the biomass with steam at elevated temperature and pressure, collection of C5 sugars from hemicellulose breakdown, cellulose hydrolysis and collection of C6 sugars from cellulose breakdown. The improvement includes conditioning of the biomass prior to the pretreatment step by heating the biomass with steam for a time period between 5 minutes to 60 minutes to achieve a steam treated biomass having a temperature of about 80 to 100° C.; and adjusting a moisture content of the steam treated biomass to about 45% to 80%. An increased recovery of C5 and C6 sugars is achieved compared to the conventional process.

摘要： A process is defined for the continuous steam pretreatment and fractionation of corn cobs and low lignin lignocellulosic biomass to produce a concentrated cellulose solid stream that is sensitive to enzymatic hydrolysis. Valuable chemicals are recovered by fractionating the liquid and vapor stream composed of hydrolysis and degradation products of the hemicellulose. Cellulosic derived glucose is produced for fermentation to biofuels. A hemicellulose concentrate is recovered that can be converted to value added products including ethanol.

摘要： Disclosed is a method of producing ethanol from lignocellulosic biomass, including a two stage steam pretreatment process. The first stage of the steam pretreatment is carried out by heating the biomass with high pressure steam to a first stage temperature of 140° C. to 180° C. for a first stage time of 30 minutes to 2 hours at a first stage pressure of 105 to 150 psig; and the second steam pretreatment stage is carried out by heating the biomass with high pressure steam to raise the biomass temperature to a second stage temperature of 190° C. to 210° C. for a second stage time of 2 to 10 minutes at a second stage pressure of 167 to 262 psig. Hemicellulose and inhibitors (inhibitory compounds) to downstream hydrolysis and fermentation are preferably removed between the first and second pretreating stages, more preferably after each pretreatment stage.

摘要： A process for the production of ethanol wherein a hydrolyzed lignocellulosic biomass is fermented in the presence of a stillage residue. The fermentation of cellulosic hydrolysates is improved by adding prior to and/or during fermentation a stillage residue side stream from a corn starch-to-ethanol process as a nutrient source for the yeast organisms used in the fermentation. Stillage residues from the grain dry mill ethanol producing process, including the whole stillage, wet cake, thin stillage, and/or syrup are added to assist as a nitrogen and nutrient source for the fermentive processes. The stillage residue is produced by any grain-to-ethanol process.

摘要： A process for the production of ethanol from biomass is disclosed. The process relates to the pretreatment of corncob biomass and includes the steps of exposing corncob to steam in a reaction vessel at an elevated temperature and reaction pressure for a preselected exposure time. Volatile compounds are continuously vented during pretreatment. The reaction pressure is released for explosive decomposition of the corncob biomass into fibrous solids and condensate. The exposure is preferably carried out at a temperature of 190-210° C. and a pressure of 190 psig to 275 psig and an exposure time of 3 to 10 minutes.
