POLYMERIC AND SOLID-SUPPORTED CATALYSTS, AND METHODS OF DIGESTING LIGNIN-CONTAINING MATERIALS USING SUCH CATALYSTS

摘要

Provided herein are solid base catalysts useful in non-enzymatic break down of lignin in biomass. The solid base catalysts may be polymeric catalysts or solid-support base catalysts with ionic moieties. Provided are also methods for at least partially depolymerizing lignin materials into various lignin digestion products using the solid base catalysts described herein.

1. A catalyst comprising basic monomers and ionic monomers connected to form a polymeric backbone,
wherein each basic monomer independently comprises at least one Bronsted-Lowry base, wherein each Bronsted-Lowry base independently comprises at least one nitrogen-containing cationic group, at least one phosphorous-containing cationic group, at least one sulfur-containing cationic group, or any combinations thereof.
