Its fields of expertise cover:

The main objectives of the research work carried out are:

• to improve the performance and reliability of tried and tested analytical methods,
• to develop or adapt new techniques and develop effective methodologies for the characterization of hydrocarbon, petroleum or related products and materials.

1. Petroleum products

Work in this field in recent years has been primarily guided by:

• research into methods to reduce analytical costs,
• changing product specifications related to environmental constraints,
• the requirements of kinetic modeling of processes.

The objective is to achieve a molecular description of families of compounds sometimes present in trace quantities in increasingly heavy oil cuts.

Examples of work carried out

• development of alternative laboratory or on-line methods to reduce operating costs and improve control of refining units,
• improvement of detection limits for catalyst poisons used in refining and petrochemical processes. Speciation of elements to improve impurity elimination processes,
• detailed analysis and relationships between composition and usage properties of fuels in the context of evolving environmental standards.

2. Products resulting from biomass conversion

The use of biomass for the production of fuels is a major issue for the coming years. New technologies will be developed and improved in order to achieve this objective. It is necessary to have an accurate description of the different compounds produced during the conversion of biomass. A coherent set of analytical methods must be implemented to obtain the desired compositional information.

Examples of work carried out:

• development of analytical methodologies to study pyrolysis oils produced by the conversion of ligno-cellulose biomass,
• detailed analysis of vegetable oil esters of various origins for the production of biodiesel.

3. Materials

The implementation of physical characterization techniques requires perfect knowledge of the measurement chain in order to be able to master the quantitative aspects of the applications and to improve the final performance of systems. Protocols for the preparation and study of samples must also be adapted to protect the information as much as possible during analysis. Finally, it is usually necessary to develop characterization methodologies based on several complementary techniques in order to determine relationships between the properties and structure of materials.

X-ray photo-electron spectroscopy

Examples of work carried out:

• improvement of signal quantification by X-ray microanalysis and XPS spectrometry applied to divided and porous solids,
• development of electronic microscopy and X-ray diffraction equipment and methods for in situ textural and structural characterization during preparation phases or in reactive medium,
• study of the acid-base properties of catalysts by NMR and IR spectroscopy of adsorbed probe molecules,
• fine description of the active metallic sites of solid catalysts by short-distance structural characterization (X-ray absorption spectrometry).
