  • Publication number: 20240050911
    Abstract: The present invention relates to a gas/liquid reactor for the oligomerization of gaseous ethylene, comprising a gaseous ethylene injection device and a liquid injection device, said injection devices advantageously being arranged so that the injection of the liquid can bring about a reduction, by shear, of the size of the ethylene bubbles, during the injection of the gaseous ethylene. The gas/liquid reactor according to the present invention may be used for any gaseous olefinic feedstock injected into a liquid phase.
