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

Fischer-Tropsch synthesis is a catalytic process to produce hydrocarbons from a syngas, which could come from biomass. It is therefore an alternative process to help reduce the share of oil in the
