This Account will focus on some recent aspects of the research performed in the author’s laboratory. Selected examples of complexes in which the ligands play an essential role in determining the molecular properties will be examined. Concerning the applications of these complexes, we will limit ourselves to some aspects related to the catalytic oligomerization of ethylene. In the search for such catalysts, we found that deprotonation of N,OH ligands chelated to Ni(II) with NaH can give rise to a range of heterometallic Na-Ni polynuclear complexes. In addition to their catalytic relevance, their magnetic properties were also investigated and have revealed in some cases Single Molecule Magnet behaviour. The diverse functions that co-catalysts may exert will be illustrated by the characterization of Cr(III) complexes obtained by reaction of fac-[Cr(NpyPNpy)Cl3] with typical co-catalysts such as MAO, EtAlCl2, AlMe3 and AlEt3. We will also discuss some polynuclear and cluster chemistry w...

In this study, the injection of catalyst particles into a dense gas-solid fluidized bed reactor is investigated using the Euler/Euler approach. Numerical simulations of horizontal catalyst+gas mixture injection through a circular-sectioned nozzle have been performed in order to study the effect of the operating conditions of an injector on the flow hydrodynamics. The study is in the context of a larger project to optimize the nozzle geometry. The nozzle is composed of two annular sections, one outer and one inner. Catalyst is injected from the central section of the nozzle with a transport gas called here "gas 1". Another gas is injected in the outer section: "gas 2". The results show that the good dispersion of the catalyst depends highly on the ratio of the velocities in the outer and the inner sections of the nozzle.
