Journal ArticleDOI
Production of biodiesel from waste frying oils.
Pedro Felizardo,M. Joana Neiva Correia,Idalina Raposo,João F. Mendes,Rui Berkemeier,João Moura Bordado +5 more
TL;DR: An increase in the amount of methanol or catalyst quantity seems to simplify the separation/purification of the methyl ester phase, as showed by a viscosity reduction and an increasing purity to values higher than 98% for methyl esters phase.
Journal ArticleDOI
Multivariate near infrared spectroscopy models for predicting methanol and water content in biodiesel.
TL;DR: The effect of some commonly used pre-processing techniques applied prior to partial least squares (PLS) and principal components regressions (PCR) in the quality of the calibration models developed to relate the near infrared spectrum of biodiesel and its content of methanol and water is analyzed.
Journal ArticleDOI
Study on the glycerolysis reaction of high free fatty acid oils for use as biodiesel feedstock
Pedro Felizardo,João N. Machado,Daniel Vergueiro,Daniel Vergueiro,M. Joana Neiva Correia,João Gomes,João Gomes,João Moura Bordado +7 more
TL;DR: In this paper, a method for pre-treatment of oils with a high content of free fatty acids (FFA) by esterification with glycerol is described, in order to reduce the FFA content.
Journal ArticleDOI
Multivariate near infrared spectroscopy models for predicting the methyl esters content in biodiesel.
TL;DR: The results confirm that NIR spectroscopy, in combination with multivariate calibration, is a promising technique to assess the biodiesel quality control in both laboratory-scale and industrial scale samples.
Journal ArticleDOI
Multivariate near infrared spectroscopy models for predicting the iodine value, CFPP, kinematic viscosity at 40 °C and density at 15 °C of biodiesel
TL;DR: The results support that NIR spectroscopy, in combination with multivariate calibration, is a promising technique applied to biodiesel quality control, in both laboratory and industrial-scale samples.
