Abstract: A process for producing furfural and levulinic acid from lignocellulose-comprising biomass is disclosed. The biomass is slurried using water and optionally an acid, subjected to hydrolysis, and then subjected to a solid/liquid separation to yield at least an aqueous fraction comprising C5 and C6 sugars and a solid fraction comprising cellulose and lignin. Furfural is obtained by adding an organic solvent to the aqueous fraction, heating at 120-220° C. for a sufficient time to form furfural, cooling, and separating an organic phase comprising at least part of the furfural from an aqueous phase. Levulinic acid is obtained by suspending the solid fraction in water and optionally an acid, heating the suspension to 140-220° C., and separating an aqueous fraction comprising the levulinic acid from a solid fraction.

Abstract: The invention provides a process for the isolation of levulinic acid and formic acid from a composition comprising formic acid and levulinic acid, said process comprising a solid-liquid separation step, a vapor removal step, and a solvent-solvent extraction step, wherein a vapor condensate vapor and/or an aqueous phase from the solvent extraction is used to wash the solid fraction. Washing with vapor condensate results in higher levulinic acid yields (higher levulinic acid recovery) as compared to washing with normal water. Washing with aqueous phase results in a less compressible filter cake. Washing first with aqueous phase and subsequently with condensate results in even higher levulinic acid yields. The process is suitable for isolating levulinic acid and formic acid from compositions made by acid hydrolysis of a lignocellulosic biomass, and also from compositions made by acid hydrolysis of sugars such as glucose and fructose.
