Predictive model for the determination of the hydrotreated vegetable oil (HVO) content in HVO/fossil diesel blends using gas chromatography coupled to mass spectrometry and multivariate analysis.

Low-carbon fuels, emitting less carbon than fossil fuels, are proposed to help in the transition to a sustainable, decarbonized transport sector. The new biofuels being studied and developed in this context include hydrotreated vegetable oils (HVO). Its chemical composition, which is the same as fossil diesel (primarily composed of linear chain hydrocarbons C12-C24), makes HVO (more homogeneous mixtures of paraffinic hydrocarbons C10-C20, containing no sulfur or aromatics) a fuel with slightly lower density than fossil diesel due to these characteristics.
