Abstract
The present invention provides processes for catalytically converting biomass to oxygenated compounds suitable for use in bioreforming processes.
Claims31
A method of converting a biomass slurry to soluble oxygenated hydrocarbons, the method comprising:
- contacting solid biomass in an aqueous slurry with hydrogen and a heterogeneous deconstruction catalyst at a deconstruction temperature and a deconstruction pressure to produce a biomass hydrolysate that comprises ethylene glycol, propylene glycol, or xylitol,
- wherein the solid biomass comprises (a) lignin and (b) at least one of cellulose and hemicellulose, and wherein at least a portion of the soluble oxygenated hydrocarbons are derived from the lignin.
