1. A method for converting a source of C6 sugar into a mixture of hydrotreated compounds comprising:
- thermocatalytically reacting a source of C6 sugar to produce a solution comprising at least one of levulinic acid and levulinic acid ester;
extracting at least one of the levulinic acid and the levulinic acid ester from the solution using a cyclic ether;
condensing at least a portion of at least one of the levulinic acid and the levulinic acid ester with at least one of C4-C11 aldehydes, C4-C11 ketones, C4-C11 esters, or C4-C11 ketoacids to produce a condensation product; and
hydrotreating at least a portion of the condensation product to provide a mixture of hydrotreated compounds.

Abstract
An integrated method for production of fuels, fuel additives, or chemicals in a biorefinery by the conversion of cellulosic materials is disclosed herein. The method is based on converting a source of C6 sugar into a mixture of hydrotreated compounds. Embodiments of the method can be highly integrated, with reagents for particular steps being provided by other steps of the process.
