1. A continuous process for the hydrolysis of ligno-cellulosic biomass comprising the steps of:
A) a contacting step, comprising contacting a ligno-cellulosic feedstock of a feedstock stream, the ligno-cellulosic feedstock comprised of a ligno-cellulosic biomass having a dry content and water with at least a portion of a solvent, wherein the dry content comprises cellulose, hemicellulose, and the weight percent of the cellulose in the dry content is greater than 5 weight percent of the dry content, the solvent comprises water soluble hydrolyzed species; wherein at least some of the water soluble hydrolyzed species are the same as the water soluble hydrolyzed species obtainable from the hydrolysis of the cellulose in the feedstock; B) maintaining the contact between the feedstock of the feedstock stream and the solvent in the presence of a catalyst composition for the hydrolysis of the cellulose, at a temperature in a temperature range selected from the group consisting of 20° C. to 200° C. and 20 to 95° C. for a time range in the range of 5 minutes to 72 hours to create a hydrolyzed product from the biomass in the feedstock; wherein the contacting step (A) further comprises introducing the ligno-cellulosic feedstock into a vessel already containing at least a portion of the solvent, introducing the catalyst composition into the vessel before, simultaneously with, or after introduction of the feedstock into the vessel, and the process further comprises step C) continuously removing a weight of the hydrolyzed product from the vessel. |
