Abstract
A method for producing levulinic acid from lignocellulosic biomass comprising hemicellulose including one or more six carbon chain compound precursors comprises the steps of hydrolyzing the lignocellulosic biomass to form a first phase comprising partially hydrolyzed lignocellulosic biomass including cellulose and lignin and a second phase comprising one or more five carbon chain sugars and one or more six carbon chain sugars from degradation of the hemicellulose, separating the first phase from the second phase, and converting at least a portion of the one or more six carbon chain sugars to levulinic acid.
