Shock treatment of corn stover

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...

Assessment of Shock Pretreatment of Corn Stover Using the Carboxylate Platform.

Corn stover was pretreated with lime and shock, a mechanical process that uses a shockwave to alter the biomass structure. Two pretreatments (lime-only and lime + shock) were evaluated using enzymatic hydrolysis, batch mixed-culture fermentations, and continuous countercurrent mixed-culture fermentation. In a 120-h enzymatic hydrolysis, shock pretreatment increased the glucan digestibility of s...

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...
