Corn stover feedstock trials to support predictive modeling

Thermogravimetric characterization of corn stover as gasification and pyrolysis feedstock

Interest in generating energy from biomass has grown tremendously in recent years. Corn stover is an agricultural by-product, which is abundant in quantity. Gasification and pyrolysis are efficient methods of harnessing energy efficiently from corn stover. The performances of mathematical models to predict the product gas quality rely on characterization of feed materials and the reaction kinet...

Anhydrous Ammonia Pretreatment of Corn Stover and Enzymatic Hydrolysis of Glucan from Pretreated Corn Stover

As a promising alternative of fossil fuel, ethanol has been widely used. In recent years, much attention has been devoted to bioethanol production from lignocellulosic biomass. In previous research, it is found that the pretreatment method named low-moisture anhydrous ammonia (LMAA) has the advantage of high conversion efficiency and less washing requirements. The purpose of this study was to e...

Sustainability of Corn Stover Harvest for Biomass

Energy Consumption of Corn Stover Size Reduction

Corn-based ethanol, the most common first generation biofuel in the US, plays an important role as a fossil fuels alternative. Second generation biofuels, which are mostly based on lignocellulosic biomass, have gained great attention in recent years. Size reduction of the lignocellulosic biomass is a key step to the efficiency of downstream processes (i.e., pretreatment, enzymatic hydrolysis, a...

The Effects of Particle Size, Different Corn Stover Components, and Gas Residence Time on Torrefaction of Corn Stover

Large scale biofuel production will be possible only if significant quantities of biomass feedstock can be stored, transported, and processed in an economic and sustainable manner. Torrefaction has the potential to significantly reduce the cost of transportation, storage, and downstream processing through the improvement of physical and chemical characteristics of biomass. The main objective of...
