as fuels for electricity production and/or as feedstock for second generation ethanol. If electricity prices are … favorable, more lignocellulosic material may be diverted for production of steam and electricity, and vice versa when ethanol … prices are more attractive. Therefore, some flexibility to divert bagasse and trash for either second generation ethanol or …

An integrated configuration of a fuel cell and an auto-thermal ethanol reformer has been studied conceptually for high … to reform aqueous ethanol at 500°C to produce hydrogen with about 3% of CO which is tolerable for an HT-PEMFC operating … aqueous ethanol reformer, the fuel for the power unit can be stored in liquid form which makes it ideal for stand-alone power …

results from each of the beverages tested were similar, except for the diet beverage, with a final ethanol concentrations of … around 25g/L, an average productivity of approximately 2g*L−1h−1 and average yields of 0.43g ethanol/g glucose. Using a diet …

fraction of 5.75% renewable energy sources. Ethanol in gasoline is a promising solution to reach this objective. In addition to … decrease the dependence on fossil fuel, ethanol contributes to reducing air pollutant emissions during combustion (carbon … the effect of ethanol (E75–E85) versus gasoline (E5) at standard and low ambient temperatures (22°C and −7°C, respectively …

A significant fraction of the energy consumption in bioethanol production … concentration and, consequently, produce wine of low (around 8.5°GL) ethanol content that must be distilled in order to meet product … shown that the alternative fermentation processes allow a significant reduction on vinasse generation and increases ethanol …

Ethanol and methyl-tertiary butyl ether (MTBE) were close substitutes in the gasoline additives market until MTBE was … banned due to the concerns about groundwater contamination, leading to a sudden and dramatic substitution toward ethanol as …-Midwestern states for which the bans were binding, with larger impacts during times of high ethanol prices relative to MTBE and crude …
