Aqueous sulfuric acid is used for hydrolysis of a biomass, constituting a hydrolysate, to produce organic compounds. Organic compounds such as furfural and hyroxymethylfurfural are formed within the hydrolysate. Heterocyclic ring opening within hyroxymethylfurfural forms levulinic acid within the hydrolysate. Furfural and levulinic acid are extracted by a biodiesel fuel oil to increase content of biodiesel fuel oil. Biodiesel fuel oil generally consists of vegetable oils, insoluble in aqueous sulfuric acid, and affords access to, extraction of furfural and levulinic acid. Extracted hydrolysate is recycled for further hydrolysis of biomass.
