Abstract
Official abstract text for this publication.
Processes to produce biofuels from biomass is provided where the biomass is contacted with an aqueous media to form a extracted biomass and at least a portion of an aqueous liquor separated from the extracted biomass containing soluble carbohydrate 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 a hydrogenolysis catalyst to form a plurality of 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 to form a pretreated biomass and then a second digestive solvent to form a solubilized pulp comprising soluble carbohydrates.
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 a 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 c…
