Claim Text:
1. A method comprising: providing a bio-based feedstock comprising lignin; contacting the bio-based feedstock with a hydrolysis catalyst and a solvent to form an intermediate product comprising carbohydrates; contacting at least a portion of the intermediate product with a hydrogenolysis catalyst in the presence of first hydrogen source to form at least some hydrogenolysis reaction products; contacting at least a portion of the intermediate stream with a hydrogenation catalyst in the presence of second hydrogen source to form at least some hydrogenation reaction products; contacting at least a portion of the intermediate stream with an aqueous phase reforming (APR) catalyst to form at least some APR reaction products; wherein at least a portion of the hydrogenolysis reaction products, at least a portion of the hydrogenation reaction products, and at a least a portion of the APR reaction products are combined to form a plurality of oxygenated intermediates, wherein a first portion of the oxygenated intermediates are recycled to form at least a portion of the solvent, wherein the hydrolysis reaction and at least one of the hydrogenolysis reaction, hydrogenation reaction, and aqueous phase reforming reaction take place in the same vessel; and processing at least a second portion of the oxygenated intermediates to form a fuel blend.
