More Information
Summary:A process of fractionation of biomass using aqueous ammonia for fractionation of biomass into lignin, cellulose and/or hemicellulose is provided herein. The process disclosed in the present invention is recovers lignin, cellulose and hemicellulose in more than 90% purity. The present invention also provides process of saccharification and fermentation of biomass using aqueous ammonia for production of soluble sugars, alcohols, acids, phenols and other desired products, or derivatives thereof. The process disclosed in the present invention is robust, cost effective and scalable.
