Increase Of Cellulose Biosynthesis

IntroductionCellulose is a complex carbohydrate that serves as the basic structural component of plant cell walls. It accounts for roughly one-third of all vegetal matter, making it the most common organic compound on earth. Due to its ubiquitous nature, cellulose and its derivatives are key resources for the agriculture, forestry, textile, and paper...

Using Ammonia Treatment to Make Biomass Pellets

IntroductionCellulosic biomass is not dense enough to be transported economically over long distances. The treated biomass must be compressed to increase its density. However, when compressed, the biomass tends not to bind sufficiently. Additionally, current additives used to increase binding characteristics of the biomass are expensive. Description...

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...
