Title:
FLOW-BASED AEROBIC DEPOLYMERIZATION OF LIGNIN
Document Type and Number:
WIPO Patent Application WO/2023/244264
Kind Code:
A3
Abstract:
Alkaline aerobic depolymerization of lignin in a permeable flowthrough reactor. Methods include flowing an aqueous reaction medium that includes lignin and a base through a lumen of an oxygen-permeable channel in the presence of oxygen gas to depolymerize the lignin to aromatic monomers.
