Title (EN) FOURIER TRANSFORM INFRARED (FTIR) CHEMOMETRIC METHOD TO DETERMINE CETANE NUMBER OF DIESEL FUELS CONTAINING FATTY ACID ALKYL ESTER ADDITIVES
(FR) PROCÉDÉ CHIMIOMÉTRIQUE INFRAROUGE À TRANSFORMÉE DE FOURIER (FTIR) PERMETTANT DE DÉTERMINER L'INDICE DE CÉTANE DE CARBURANTS DIESEL CONTENANT DES ADDITIFS D'ESTER ALKYLIQUE D'ACIDE GRAS
Abstract: front page image
(EN)The present invention is a method to determine the cetane number of a diesel fuel containing a fatty acid alkyl ester including determining the infrared spectrum of the fuel and correlating the spectrum to the cetane number using a multivariate-based Mid-FTIR model. The fatty acid alkyl ester may be rapeseed methyl ester and the infrared spectrum includes the frequency ranges 4900-3500 cm-1 and 2200-1624 cm-1 or the frequency ranges 4900-3500 cm-1, 2200-1800 cm-1 arid 1700-1624 cm-1.
(FR)L'invention concerne un procédé qui permet de déterminer l'indice de cétane d'un carburant diesel contenant un ester alkylique d'acide gras. Ce procédé consiste à déterminer le spectre infrarouge du carburant et à corréler le spectre à l'indice de cétane au moyen d'un modèle Mid-FTIR à plusieurs variables. L'ester alkylique d'acide gras peut être de l'ester méthylique de colza et le spectre infrarouge comprend les plages de fréquence 4900-3500 cm-1 et 2200-1624 cm-1 ou les plages de fréquence 4900-3500 cm-1, 2200-1800 cm-1 et 1700-1624 cm-1.
