Abstract
Official abstract text for this publication.
Biomass is contacted with an aqueous media to form an extracted biomass. An aqueous liquor separated from the extracted biomass is treated with a purification substrate to form a treated carbohydrate stream having less than 35% of the sulfur content and less than 35% of the nitrogen content, based on the untreated aqueous liquor stream, prior to contact with an aqueous phase reforming catalyst to form oxygenated intermediates that can be further processed to form a liquid fuel. An extracted biomass solids stream is also separated from the extracted biomass which is contacted with a first digestive solvent and then a second digestive solvent to form a solubilized pulp. This solublilized pulp may be combined with the aqueous liquor stream or combined to an aqueous reforming reaction system or recycled to the aqueous media to be processed further for an effective process to produce the liquid fuel.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: (i) providing a biomass containing celluloses, hemicelluloses and lignin; (ii) contacting the biomass with an aqueous media to form an extracted biomass comprising celluloses, hemicelluloses, soluble carbohydrates and lignin; (iii) separating at least a portion of an aqueous liquor from the extracted biomass thereby providing the aqueous liquor stream comprising soluble carbohydrates and a pretreated biomass solids stream comprising…
