Development of a thermoeconomic methodology for optimizing biodiesel production. Part II: Manufacture exergetic cost and biodiesel production cost incorporating carbon credits, a Brazilian case study
The purpose of this study is to carry on a thermoeconomic analysis at a biodiesel production plant considering the irreversibilities in each step (part I: biodiesel plant under study and functional thermoeconomic diagram ...
New porphyrins tailored as biodiesel fluorescent markers
(ELSEVIER SCI LTD, 2011)
This work reports the synthesis, characterization, and evaluation of new porphyrins tailored to become biodiesel fluorescent markers. The compounds were obtained by the synthetic modification of the commercially available ...

An overview of biodiesel soil pollution: Data based on cytotoxicity and genotoxicity assessments
(Elsevier B.V., 2012-01-15)
Biodiesel production has received considerable attention in the recent past as a nonpolluting fuel. However, this assertion has been based on its biodegradability and reduction in exhaust emissions. Assessments of water ...
Les biocarburants en Argentine: facteurs et enjeux de la production de biodiesel de sojaBiofuel production in Argentina: factors and challenges of soybean biodiesel
(EDP Sciences, 2012-06)
In 2006, Argentina has sanctioned a national law to regulate biofuel production and consumption. Since 2007, soybean actors started producing biodiesel for international market -especially to Europe- and the country quickly ...
Fast Determination of Biodiesel Content in Commercial Diesel/Biodiesel Blends by Using Digital Images and Multivariate Calibration
(Japan Society for Analytical Chemistry, 2017-11)
A new simple, rapid and inexpensive analytical method was developed to determine the biodiesel percentage in biodiesel/ diesel blends through simple digital images of samples obtained by scanning with a commercial scanner. ...
Biodiesel e os pequenos consumidores.
(Cultivar, Pelotas, v. 8, n. 89, p. 33, set. 2006., 2012)
Biodegradability of diesel and biodiesel blends
The biodegradability of pure diesel and biodiesel and blends with different proportions of biodiesel (2% (commercial); 5% and 20%) was evaluated employing the respirometric method and the redox indicator 2,6-dichlorophenol ...
Heterogeneous catalysis afford biodiesel of babassu, castor oil and blends
This work describes the preparation of babassu, castor oil biodiesel and mixtures in various proportions of these oils, using alkaline compounds of strontium (SrCO3 + SrO + Sr (OH)2) as heterogeneous catalysts. The mixture ...
