Abstract
A process for the production of ethoxylated and hydroxylated lignin fractions, cellulose, lignocellulosic sugars, and ethanol in high yields is provided. The process comprises steaming, pretreatment, chemical recovery, saccharification, and optionally fermentation. A combination of pretreatment conditions is provided resulting in simultaneously high yields of ethoxylated or hydroxylated lignin and cellulose or cellulosic sugars and hernicellulosic sugars. High yield production of ethanol through fermentation can be obtained using this process.
