Abstract
In some variations, a process for converting a biomass feedstock into a product comprises: providing a biomass feedstock containing cellulose, hemicellulose, and lignin; providing a reaction solution comprising a fluid and optionally a pretreatment chemical; feeding the biomass feedstock and the reaction solution to a biomass digestor operated to pretreat the biomass feedstock, thereby generating a digested stream comprising a solid-liquid mixture and a digestor vapor; discharging the digested stream to a vapor-separation unit operated to separate the digestor vapor from the solid-liquid mixture; optionally recycling at least a portion of the digestor vapor within the process; conveying the solid-liquid mixture, or a portion thereof, to a hydrolysis reactor operated to hydrolyze the cellulose and/or the hemicellulose to monomeric and/or oligomeric sugars; and converting the monomeric and/or oligomeric sugars to a product. Many variations are disclosed.
