Analysis and characterization

In the aviation sector, fuels derived from hydrotreated vegetable oils (HEFA a) are seen as an alternative to petroleum based Jet A-1 b to reduce the environmental footprint of air transport. However

The reduction in IC engine particle emissions requires a detailed knowledge of the physicochemical processes at work during combustion. While fuels have long since been considered as a constant for

Alumina, the archetypal material used for hydrotreatment catalyst supports, has a porous structure at supramolecular scales, determining the transport of oil feeds within it. This structure is largely

Transition aluminas a, widely used as catalyst supports, play a key role in numerous refining processes. Today, the need to develop new and more efficient catalysts demands, among other things, better

The value of X-ray photoelectron spectroscopy (XPS) resides in its capacity to supply information on the surface elementary composition (a few nm) and the chemical environment of the atoms probed

The development of more efficient hydrotreatment catalysts, based on molybdenum (Mo), requires advanced characterization methods that allow materials to be studied in conditions that match those of

Improving the reactional performance of a catalytic material (obtained by applying an active phase onto oxide grains) requires a better understanding of the mechanisms involved in the reaction. More
