Methods of producing sugars from biomass feedstocks

摘要

Provided herein are catalysts useful in non-enzymatic saccharification processes. The catalysts can be polymeric catalysts or solid-supported catalysts with acidic and ionic moieties. Provided are also methods for hydrolyzing cellulosic materials into monosaccharides and/or oligosaccharides using the catalysts described herein.

主权项

1. A method of producing one or more sugars from feedstock, comprising:
combining feedstock and a polymeric catalyst to form a reaction mixture,
wherein the feedstock is selected from the group consisting of softwood, hardwood, sugarbeet pulp, food waste, enzymatic digestion residuals, and beer bottoms, or any combination thereof, andwherein the polymeric catalyst comprises acidic monomers and ionic monomers connected to form a polymeric backbone, wherein a plurality of acidic monomers independently comprises at least one Bronsted-Lowry acid, and wherein a plurality of ionic monomers independently comprises at least one nitrogen-containing cationic group, at least one phosphorous-containing cationic group, or a combination thereof; anddegrading the feedstock in the reaction mixture to produce a liquid phase and a solid phase, wherein the liquid phase comprises one or more sugars, and the solid phase comprises residual feedstock.
