Abstract:
When processing cellulosic biomass, it may be desirable for a digestion unit to operate without being fully depressurized for process efficiency purposes. Methods for processing cellulosic biomass may comprise providing a biomass conversion system comprising a pressurization zone and a digestion unit that are operatively connected to one another; providing cellulosic biomass at a first pressure; introducing at least a portion of the cellulosic biomass into the pressurization zone and pressurizing the pressurization zone to a second pressure higher than the first pressure; after pressurizing the pressurization zone, transferring at least a portion of the cellulosic biomass from the pressurization zone to the digestion unit, which is at a third pressure that is less than or equal to the second pressure but higher than the first pressure; and digesting at least a portion of the cellulosic biomass in the digestion unit to produce a hydrolysate comprising soluble carbohydrates.
