Ethanol Production with Dilute Acid Hydrolysis Using Partially Dried Lignocellulosics

U.S. Patent 6,660,506


Technology Description

A process of converting lignocellulosic biomass to ethanol, comprising hydrolyzing lignocellulosic materials by subjecting dried lignocellulosic material in a reactor to a catalyst comprised of a dilute solution of a strong acid and a metal salt to lower the activation energy (i.e., the temperature) of cellulose hydrolysis and ultimately obtain higher sugar yields.
