Using the electrochemical impedance spectroscopy to characterize carbon steel in biodiesel medium
(2012-12-01)
Electrochemical impedance spectroscopy measurements using two carbon steel electrodes in soybean biodiesel medium, produced by methylic route, were performed in an electrochemical cell that allows positioning the two ...
Influence of vegetable oil in the viscosity of biodiesel-a review
(2008-12-01)
Viscosity is a measure fluid resistance to flowing, affecting the fuel spray in the combustion chamber and, by this way, thus the formation of carbon deposits. The analysis of the influence of vegetable oil viscosity in ...
Analysis of catalytic potential of a new heterogeneous catalyst in the preparation of biodiesel
(2018-01-01)
In this work was investigated the catalytic potential of a new heterogeneous catalyst of stoichiometry Ca0.5K0.5TiCu0.25O3, with double perovskite structure, in the preparation of biodiesel via ethylic route. The catalyst ...

Direct simultaneous determination of Pb(II) and Cu(II) in biodiesel by anodic stripping voltammetry at a mercury-film electrode using microemulsions
(2013-01-01)
A mercury film electrode was used to determine direct and simultaneously Pb(II) (at -410 mV) and Cu(II) (at -100 mV) in biodiesel by anodic stripping voltammetry. A linear response was obtained for Pb(II) and Cu(II) in the ...
