Abstract

The nature and size of particles, formed under conditions of the ethylene oligomerization in the systems based on nickel bis(acetylacetonate) with Et2AlCl or Et2AlCl·Cl2AlEt (Al: Ni=50: 1), have been determined using ex situ HRTEM, electron diffraction and EDAX in combination with EPR spectroscopy and kinetic studies. It was revealed that the average sizes of Ni-containing particles depend on the nature of cocatalyst and are ∼3.5 and ∼6 nm for the systems derived from Et2AlCl and Et2AlCl·Cl2AlEt, respectively. It was shown that these nanoparticles act as the carriers of catalytically active sites during the C2H4 conversion.
