Thermodynamic analysis of direct steam reforming of ethanol in molten carbonate fuel cell
(Asme-amer Soc Mechanical Eng, 2014)
Comparative LCA of ethanol versus gasoline in Brazil using different LCIA methods
(Springer HeidelbergHeidelbergAlemanha, 2013)
What prospects for the brazilian ethanol sector?
(Wiley, 2017-04)
Brazilian ethanol is derived from sugarcane and is mostly used domestically as a transportation fuel either pure or mixed with gasoline. Brazilians will fill their cars with pure ethanol when its pump price in energy ...
Ethanol production using hemicellulosic hydrolyzate and sugarcane juice with yeasts that converte pentoses and hexoses
(Academic Journals, 2015)
The use of vegetable biomass as substrate for ethanol production could reduce the existing usage of fossil fuels, thereby minimizing negative environmental impacts. Due to mechanical harvesting of sugarcane, the amount of ...
PtSnIr/C Anode Electrocatalysts: Promoting Effect in Direct Ethanol Fuel Cells
(SOC BRASILEIRA QUIMICASAO PAULO, 2013-08-02)
This study investigates the promoting effect of PtSnIr/C (1:1:1) electrocatalyst anode, prepared by polymeric precursor method, on the ethanol oxidation reaction in a direct ethanol fuel cell (DEFC). All of the materials ...

Plant-wide control design for fuel processor system with PEMFC
(Pergamon-Elsevier Science Ltd, 2012-10)
The main contribution of this work is the application of a novel technique for the plant- wide control design to a challenging bio-ethanol processor system for hydrogen produc- tion. It is based on steam reforming, followed ...
Biofuels potential in Guyana
(ECLAC, 2007-02)
Abstract
Guyana depends on imported fuel to meet the needs of its transport sector. In recent years, pricesof derivatives of petroleum have increased significantly, further widening the current account
deficit. In 2005, ...
Temporal variation of ethanol in rainwater from the sugar cane belt of São Paulo State (Brazil)
(2019-11-01)
This work presents the first comprehensive assessment of ethanol dissolved in rainwater of São Paulo State's sugar cane belt, considering the period from 2012 to 2017. Ethanol concentrations ranged from 0.25 to 20.9 μmol ...
