Alumina supported NiW catalysts with components concentrations varying in a wide range were systematically studied in order to optimize a catalyst for further industrial uses. The genesis of the active phase was examined by using several physicochemi

Metallic, oxide and hydroxide environments of magnesium are clearly identified by X-ray photoelectron spectroscopy from chemical shift of Mg 1s and Mg 2p photopeaks. Unfortunately, Mg3N2 cannot be distinguished from MgO through these two peaks. In th

Hydrogenation of 2-methylbuta-1,3-diene (isoprene) under helium flow in the absence of gaseous hydrogen is used to reveal and titrate reactive hydrogen species present in MoS2/γ-Al2O3 and Cu-Zn-O catalysts previously treated under hydrogen. Among th

Characterization of the sulphided Ni-MoS 2 state supported on various carriers (aluminates, zirconia) has been undertaken in order to study the influence of the carrier on the genesis of the promoted active phase, refered to as the “NiMoS” phase.

Hydrogenation of the vanadyloctaethylporphyrin VO(OEP), is a reversible reaction which may occur without a catalyst. The thermodynamic data have been deduced from experiments performed in a batch reactor. Both ΔHo and ΔSo are positive; this can be
