Abstract: A reactor vessel system including: a first reactor vessel having a hydrolysate and liquid extraction screen, a first region above the extraction screen that is maintained at conditions promoting a hydrolysis reaction in the cellulosic material, a second region below the extraction screen in which the hydrolysis is substantially suppressed and a wash liquid inlet below the extraction screen providing wash liquid at a temperature below a hydrolysis temperature; a transport pipe having an inlet coupled to the first reactor vessel and an outlet coupled to a second reactor vessel, and the second reactor vessel includes a liquid discharge that extracts a portion of liquid from the second reactor vessel and directs the portion of liquid to the first reactor vessel or to the transport pipe.

Abstract: A method to process cellulosic material in a treatment vessel including: introducing the cellulosic material to a processing chamber of the vessel; adding heat energy or pressure to the vessel to hydrolyze the cellulosic material in the processing chamber and dissolve hemi-cellulosic from the cellulosic material; compressing the cellulosic material in the processing chamber; extracting the dissolved hemi-cellulosic material through a screen from the processing section; draining the extracted hemi-cellulosic material from the vessel; and discharging the cellulosic material from the vessel separately from the extracted hemi-cellulosic material.
