Emergy analysis for transportation fuels produced from corn stover in China

Life cycle assessment of the production of hydrogen and transportation fuels from corn stover via fast pyrolysis

This life cycle assessment (LCA) evaluates and quantifies the environmental impacts of the production of hydrogen and transportation fuels from the fast pyrolysis and upgrading of corn stover. Input data for this analysis come from Aspen Plus modeling, a GREET model database and a U.S Life Cycle Inventory Database. SimaPro 7.3 software is employed to estimate the environmental impacts. The resu...

Use of Distillers By-products and Corn Stover as Fuels for Ethanol Plants

Dry-grind ethanol plants have the potential to reduce their operating costs and improve their net energy balances by using biomass as the source of process heat and electricity. We utilized ASPEN PLUS software to model various technology bundles of equipment, fuels and operating activities that are capable of supplying energy and satisfying emissions requirements for dry-grind ethanol plants of...

Speciation of Sulfur in Biochar Produced from Pyrolysis and Gasification of Oak and Corn Stover

The effects of feedstock type and biomass conversion conditions on the speciation of sulfur in biochars are not well-known. In this study, the sulfur content and speciation in biochars generated from pyrolysis and gasification of oak and corn stover were determined. We found the primary determinant of the total sulfur content of biomass to be the feedstock from which the biochar is generated, w...

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...
