Electrochemical CO stripping on nanosized Pt surfaces in acid media: A review on the issue of peak multiplicity
(2018-04-15)
This manuscript reviews the complex behavior of the electrochemical oxidation of adsorbed CO (CO stripping) on Pt nanoparticles in acid media. While on low-index Pt single crystals the so-called CO stripping generally ...
Mass Transfer Performance of Ethanol Removal by CO2 Stripping in Different Pneumatic Bioreactors
(2020-04-01)
The hydrodynamics and mass transfer characteristics of ethanol stripping with CO2 were evaluated for a 2.0-L pneumatic bioreactor operated in bubble column (BC), concentric-tube airlift (CTA), and split-cylinder airlift ...
Avaliação da transferência de calor em fermentações alcoólicas convencional e extrativa
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2019-02-26)
The inhibitory effect of ethanol on yeast and the temperature rise during the fermentation are the major drawbacks of the conventional ethanol production process. The use of extractive alcoholic fermentation with CO2 ...
Estudo do processo integrado de fermentação alcoólica extrativa com CO2 com desidratação por adsorção e recuperação por absorção
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2022-06-30)
To minimize the effects of ethanol inhibition, increase productivity, and reduce energy and environmental footprint, different strategies of ethanol removal by gas stripping with CO2 during alcoholic fermentation have been ...
Estudo da produção de etanol de sacarose por fermentação extrativa utilizando arraste com dióxido de carbono
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2016-04-18)
The ethanol accumulated in the broth during fermentation is the main component toxic to
yeast, causing slower yeast growth and decreased ethanol production. One way of overcoming
this inhibition effect is to use extractive ...
Fermentação alcoólica extrativa com remoção de etanol por arraste com CO2 e recuperação por absorção
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2019-02-28)
Ethanol removal by CO2 stripping during alcoholic fermentation is one way of overcoming the problem of inhibition by the ethanol. However, the lack of efficient methods to recover the removed ethanol still makes the use ...
Simultaneous determination of Cu, Pb, Cd, Ni, Co and Zn in bioethanol fuel by adsorptive stripping voltammetry and multivariate linear regression
(Elsevier, 2014-08)
In this work it is proposed the one-voltammogram simultaneous determination of Cu(II), Pb(II), Cd(II),Ni(II), Co(II), and Zn(II) at ppb and sub-ppb levels in bioethanol fuel samples by adsorptive stripping voltammetry.Mixed ...
Remoção de etanol por stripping empregando dióxido de carbono
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2014-12-15)
In the ethanol fermentation processes, the product inhibition phenomenon limits the ethanol concentration in the fermented wine around 10% v.v-1, which results in a large volume of vinasse (around 12Lvinasse/Lethanol) and ...
ALMA Evidence for Ram Pressure Compression and Stripping of Molecular Gas in the Virgo Cluster Galaxy NGC 4402
(IOP Publishing, 2020)
High-resolution (1 '' x 2 '') Atacama Large Millimeter Array CO(2-1) observations of the ram pressure stripped galaxy NGC 4402 in the Virgo cluster show some of the clearest evidence yet for the impacts of ram pressure on ...
