ABSTRACT:
A process and apparatus for the conversion of waste cellulose to glucose wherein an aqueous slurry of waste cellulose is acid hydrolyzed includes continuously feeding an aqueous slurry of waste cellulose into an inlet port with a twin screw extruder, continuously reacting the cellulose with water in the presence of an acid catalyst at elevated temperature and pressure in a reaction zone disposed in the extruder between the inlet port and an outlet port while continuously conveying same to the outlet port and at least quasi-continuously discharging the reacted cellulose from the extruder while maintaining the elevated temperature and pressure in the reaction zone by forming a dynamic seal zone at the upstream end of the reaction zone and valving the discharge downstream of the outlet port.
