Prediction of properties of biodiesel-diesel blends using spectrofluorimetry and multivariate calibration

Abstract: © Versita Sp. z o.o. Received 21 February 2012; Accepted 19 April 2012 Keywords: Concentration • Specific gravity • Viscosity • Spectrofluorimetry • Multivariate calibrationRegressions based on fluorescence spectroscopy were developed to provide relatively inexpensive and rapid measurements of the concentration, viscosity, and specific gravity of biodiesel-diesel blends. The methods involved obtaining a mathematical model from spectrofluorimetric data and data from a given property (concentration, dynamic visc… Show more

“…In the literature there are models to predict some biodiesel properties: Meira et al (2012) 5 used fluorescence spectroscopy to predict the kinematic viscosity and density of biodiesel/diesel blends by using the PLSR. Meng et al (2014) 6 applied artificial neural network (ANN) to predict the kinematic viscosity of biodiesel with the data collected from the literature, using mass fractions of methyl esters.…”

“…Biodiesel is traditionally obtained by the transesterification reaction of a fat or oil with short chain alcohols in the presence of a catalyst [1]. The most attractive features of this biofuel are the possibility of production from vegetable oils and recycled fats, its high miscibility with petrochemical diesel, its biodegradability, and its low or null content of sulfur derivatives, sulfur being the major cause of atmospheric pollution [2].…”
