Optimal gasoline tax in developing, oil-producing countries: the case of Mexico
(Centro de Investigación y Docencia Económicas, División de Economía, 2016)
Estimating the gasoline components and formulations toxicity to microalgae (Tetraselmis chuii) and oyster (Crassostrea rhizophorae) embryos: an approach to minimize environmental pollution risk
(2007)
Even though petrochemical contamination frequently occurs in the form of oil spills, it is thought that a greater danger to coastal habitats is posed by chronic petrochemical toxicity associated with urban run-off, in which ...
A sensor array based on mass and capacitance transducers for the detection of adulterated gasolines
(ELSEVIER SCIENCE SA, 2009)
The simultaneous use of different sensors technologies is an efficient method to increase the performance of chemical sensors systems. Among the available technologies, mass and capacitance transducers are particularly ...
Multiscale Strategic Planning Model for the Design of Integrated Ethanol and Gasoline Supply Chain
(Wiley, 2013-12)
The design and planning of an integrated ethanol and gasoline supply chain is addressed, and is composed of harvest-ing and production sites for ethanol, petroleum refineries, distribution centers where blending takes place, ...
A cost-effective model for the gasoline blend optimization problem
(Wiley, 2016-03)
Gasoline blending is a critical process with a significant impact on the total revenues of oil refineries. It consists of mixingseveral feedstocks coming from various upstream processes and small amounts of additives to ...
Evaluation of the lubrication of ethyl oleate and ethyl octanoate as gasoline additive
(Associação Brasileira de Petróleo e Gás, 2019)
Determination of Mo and V in multiphase gasoline emulsions by electrothermal atomic absorption spectrometry
(2006)
This paper proposes an alternative analytical method using electrothermal atomic absorption spectrometry to determine Mo and V in multiphase gasoline emulsions. Samples were prepared by mixing gasoline with a nitric acid ...
Screening Brazilian Commercial Gasoline Quality by ASTM D6733 GC and Pattern-Recognition Multivariate SIMCA Chemometric Analysis
(Vieweg, 2009-04-01)
The combination of ASTM D6733 gas chromatographic fingerprinting data with pattern-recognition multivariate soft independent modeling of class analogy (SIMCA) chemometric analysis provides an original and alternative ...
Expanding the potentialities of standard dilution analysis: Determination of ethanol in gasoline by Raman spectroscopy
(2017-07-01)
This work describes the application of standard dilution analysis (SDA) in Raman spectroscopy, demonstrating the versatility of this new calibration method. A flow system (FA) was developed for ethanol determination in ...
