Bioenergy and Biorefinery: Feedstock, Biotechnological Conversion, and Products

Effect of Agricultural Feedstock to Energy Conversion Rate on Bioenergy and GHG Emissions

Taiwan is eager to develop renewable energy because it is vulnerable to energy price distortion and ocean level rise. Previous studies show bioenergy technologies can be applied mutually, but pay little attention on feedstocks to energy conversion rate, which has potential influences on policy making in renewable energy and environment. This study employs a price endogenous mathematical program...

Lignocelluloses Feedstock Biorefinery as Petrorefinery Substitutes

The material needs from our society are reaching the crisis point, as the demand for resources will soon exceed the capacity of the present fossil resource based infrastructure [1]. Currently, fossil-based energy resources, such as petroleum, coal, and natural gas, are responsible for about three quarters of the primary energy consumption in our world. While decreasing crude-oil reserves, enhan...

Integration of Feedstock Assembly System and Cellulosic Ethanol Conversion Models to Analyze Bioenergy System Performance

Research barriers continue to exist in all phases of the emerging cellulosic ethanol biorefining industry. These barriers include the development of sustainable and abundant biomass feedstock, the assembly of viable assembly systems formatting the feedstock and moving it from the field (e.g., the forest) to the biorefinery, and improving conversion technologies. Each of these phases of cellulos...

Plant Feedstock Genomics for Bioenergy Awardee Meeting

Biotechnological Products and Process Engineering

Hydrogen gas (∼60% H2) was produced in a continuous flow bioreactor inoculated with heat-treated soil, and fed synthetic wastewater containing glucose (9.5 g l). The pH in the bioreactor was maintained at 5.5 to inhibit consumption of H2 by methanogens. The objective of this study was to characterize bacterial communities in the reactor operated under two different hydraulic retention times (HR...
