Process selection decisions and the mass flows are the decision variables, and minimization ethanol production cost for a specific production target is the objective function. The model determined the minimum ethanol cost to be Rs. 70/l ($1.05/l) for a biorefinery producing 100 Mg/month of ...
Fuel ethanol has not been as successful in the EU as the United States and Brazil mainly due to the fact that automobiles using diesel/biodiesel account for a majority of usage. Additionally, another contributing factor to the stagnant EU fuel ethanol production is the lower cost of imported ...

Ethanol production from sugarcane in India: Viability, constraints and implications In 2008 India imported 128.15 million metric tons of crude, constituting 75% of its total petroleum consumption for that year. By 2025 it will be importin... AK Mino 被引量: 1发表: 2010年 Ethanol producers go ...

and diverting grains to ethanol production at the expected rate. If India decides to refocus on ethanol produced from waste, it has a great opportunity to become a global leader in sustainable biofuel policy. Since these wastes are currently routinely burned, which contributes to smog, doing so ...
Despite a jump in production, U.S. ethanol stocks dropped significantly last week, partly owing to a sharp rebound in gasoline demand, which neared three-year highs. But record exports have been the factor keeping U.S. ethanol supplies in check over the last several months, even as output...
The major cost components in bioethanol production from lignocellulosic biomass are the pretreatment and the enzymatic hydrolysis steps. In fact, these two process are someway interrelated too where an efficient pretreatment strategy can save substantial enzyme consumption. Pretreatment step can also affect...
This is an energy-intensive process and contributes over 50% to the total cost of ethanol production.5 Due to the first oil crisis of 1973, Brazil started in 1975 the ProAlcohol program to produce fermentation alcohol from sugar cane for its use as fuel in gasohols. Since then, the ...
