Development of optimum pretreatment condition for simultaneous production of bioethanol and levulinic acid from lignocellulosic biomass

摘要

The present invention relates to a process for the production of levulinic acid from a liquid hydrolyzate produced during a bioethanol production process while improving the yield of bioethanol production by establishing optimal conditions for the pretreatment of sulfuric acid to lignocellulosic biomass, .
