Commercial additives for sulfur control in FCC gasoline: overall analysis of their impact on LCO and gasoline
(Elsevier, 2013-09)
Experiments with a commercial equilibrium catalyst and mixtures with a commercial additive for sulphur reduction in gasoline were performed in a CREC Riser Simulator reactor to study the impact of three different proportions ...
GC Fingerprints Coupled to Pattern-Recognition Multivariate SIMCA Chemometric Analysis for Brazilian Gasoline Quality Studies
(Vieweg, 2009-10-01)
ASTM D6729 gas chromatographic fingerprinting coupled to pattern-recognition multivariate soft independent modeling of class analogy (SIMCA) chemometric analysis provides an original and alternative approach to screening ...

(Vieweg, 2009-10-01)
ASTM D6729 gas chromatographic fingerprinting coupled to pattern-recognition multivariate soft independent modeling of class analogy (SIMCA) chemometric analysis provides an original and alternative approach to screening ...
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 ...
Screening Brazilian automotive gasoline quality through quantification of saturated hydrocarbons and anhydrous ethanol by gas chromatography and exploratory data analysis
(Vieweg, 2007-05-01)
In this paper a set of Brazilian commercial gasoline representative samples from São Paulo State, selected by HCA, plus six samples obtained directly from refineries were analysed by a high-sensitive gas chromatographic ...

Screening analysis to detect adulterations in Brazilian gasoline samples using distillation curves
(elservir, 2004)
Data on evaporated fraction temperatures obtained from the distillation curves of Brazilian gasolines were employed to identify
adulterated samples by applying the Soft Independent Modeling of Class Analogy (SIMCA) model. ...
Ultrafast gas chromatography method with direct injection for the quantitative determination of benzene, toluene, ethylbenzene, and xylenes in commercial gasoline
(2017-04-01)
Benzene, toluene, ethylbenzene, and xylenes are some of the most hazardous constituents found in commercial gasoline samples; therefore, these components must be monitored to avoid toxicological problems. We propose a new ...
Screening Brazilian commercial gasoline quality by hydrogen nuclear magnetic resonance spectroscopic fingerprintings and pattern-recognition multivariate chemometric analysis
(Elsevier B.V., 2010-06-30)
The identification of gasoline adulteration by organic solvents is not an easy task, because compounds that constitute the solvents are already in gasoline composition. In this work, the combination of Hydrogen Nuclear ...
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 ...
