Lignocellulosic Biomass Pretreatment Using Gaseous Ammonia and Combinations with Hot Inert-Carrier Gases

IntroductionTo achieve high yields of glucose and other products for use in biofuels and bio-based chemicals, lignocellulose must first be pretreated. The goal of pretreatment is to decrease the crystallinity of cellulose, increase the biomass surface area, remove hemicellulose, and break the lignin seal. Current pretreatments use liquid ammonia, dilute...
