Economical Methods For Performing Oxidative Catalytic Pretreatment Of Plant Biomass Using A Homogeneous Catalyst System
WARF: P200223US02

Inventors: Shannon Stahl, Zhaoyang Yuan, Eric Hegg, David Hodge, Bryan Bals


The Invention
An improved alkaline pretreatment of biomass is provided that uses a homogenous catalyst with one or more metals and metal coordinating ligands, wherein the homogeneous catalyst is used with at least two oxidants in an oxidation reaction to catalytically pretreat lignocellulosic biomass. In one embodiment, hydrogen peroxide and oxygen are utilized as co-oxidants during alkaline-oxidative pretreatment to improve biomass pretreatment and increase enzymatic digestibility. In one embodiment, the homogenous catalyst is copper (II) 2,2′-bipyridine (Cu(bpy)). Related methods are also disclosed to improve the economic feasibility of production of lignocellulose derived sugars.
