Halogens and metals speciation in bio-oils

The iCMCE² chair develops analytical methodologies for the analysis of halogens and metals in new generation bio-oils (pyrolysis, algae).

Bio-oils obtained from the most recent pyrolysis process or algae hydrothermal liquefaction process represent an analytical challenge by far more important than those associated to heavy cuts obtained from conventional oils. Moreover, these molecules are found along large ranges of polarity, volatility and size depending on the samples which makes it difficult to use a single analytical technique. Our knowledge of these highly complex matrices remains very partial and is a true drag on the development of eco-efficient production and treatment processes for bio-oils.

On this basis, we work on the extension of the available chromatographic separations range to be hyphenated to elementary analysis for the exhaustive characterization and the quantification of the species contained in these new generation bio-oils.

Dates: project started in 2021
