Caractérisation de carburants alternatifs par chromatographie d'exclusion stérique et résonance magnétique nucléaire

Abstract : Size Exclusion Chromatography and High Resolution and Solid State NMR analysis are combined to study hydroconversion products. In a first part, several catalysts were examined to produce biofuel from jatropha oil. By using an n-alcanes standards calibration for SEC, and high resolution NMR, fuel composition and structural identification were easily determined. These two analytical tools were also applied to characterisation of heavy molecular hydrocarbons from non conventional crude oils, liquid coals and derived products such as asphaltenes and pre-asphaltenes. Specific NMR pulse sequences were tested and applied to liquid or solid compounds for quantitatively determination of aromatic and aliphatic carbons.
