Title
(EN) METHOD FOR MEASURING BIODIESEL CONCENTRATION IN A BIODIESEL DIESEL OIL MIXTURE
(FR) PROCÉDÉ POUR MESURER UNE CONCENTRATION EN BIODIESEL DANS UN MÉLANGE DE CARBURANT BIODIESEL-DIESEL
Abstract
(EN)
This patent presents a method for measuring the concentration of biodiesel in a homogeneous biodiesel-diesel oil mixture using mid infrared radiation for use as fabrication monitor, quality control, law enforcement and multi-fueled vehicles. The method is characterized by the use of mid infrared absorption measurement in the range from 1870 to 1600 cm-1 (5347.6 to 6250.0 nm) which corresponds to the carbonyl group absorption peak (C=O) that is only present in biodiesel. Both intensity and area of the carbonyl absorption peak present power law dependence with the biodiesel percentile in the biodiesel-diesel oil mixture.
(FR)
L'invention porte sur un procédé pour mesurer la concentration d'un biodiesel dans un mélange de carburant biodiesel-diesel homogène à l'aide d'un rayonnement infrarouge moyen pour une utilisation en tant que dispositif de surveillance de fabrication, de contrôle qualité, d'application de la loi et pour des véhicules à multiples carburants. Le procédé est caractérisé par l'utilisation d'une mesure d'absorption en infrarouge moyen dans la plage de 1870 à 1600 cm-1 (5347,6 à 6250,0 nm) qui correspond au pic d'absorption du groupe carbonyle (C=O) qui est uniquement présent dans le biodiesel. À la fois l'intensité et l'aire du pic d'absorption de carbonyle présentent une dépendance par rapport à la loi de puissance avec le pourcentage en biodiesel dans le mélange de carburant biodiesel-diesel.
