Patent number: 8328947Abstract: A method is provided for hydrolyzing polysaccharides in a lignocellulosic feedstock to produce monosaccharides or pretreating a lignocellulosic feedstock, in which an aqueous slurry of the lignocellulosic feedstock is fed into a pressurized dewatering zone wherein the feedstock is partially dewatered and then is compressed into a plug. The plug is introduced into a reaction zone that operates at a pressure (Pr) equal to greater than about 90 psia and under suitable temperature and pH conditions to hydrolyze the polysaccharides or pretreat the feedstock. The plug provides a pressure seal between the outlet of the dewatering zone and the reaction zone. The pressure (Pdwi) of the aqueous slurry of the lignocellulosic feedstock at the inlet of the dewatering device is related to Pr as follows: 0??P<the lesser of [(Pr?20 psia) and 220 psia], and where ?P is the absolute difference in pressure between Pr and Pdwi in psia.Type: GrantFiled: August 27, 2009Date of Patent: December 11, 2012Assignee: Iogen Energy CorporationInventors: Vijay Kumar Anand, Stephen Rowland, Patrick Foody, Sr.
