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.
Claims19
A process for the oligomerization of a gaseous olefinic feedstock, comprising:
- the contact of a liquid comprising a catalytic system comprising a metal catalyst, at least one activator and at least one additive, and optionally a solvent;
- and the gaseous olefinic feedstock by a gas injection device and a liquid injection device, said injection devices being arranged so that the injection of the liquid brings about a reduction, by shear, in the size of the gaseous olefinic feedstock bubbles, said process using a gas/liquid reactor for the oligomerization of the gaseous olefinic feedstock comprising a gas injection device (3) comprising at least one gas injection orifice and a liquid injection device (12) comprising at least one liquid injection orifice, each gas injection orifice being located close to an orifice of the liquid injection device (11) and positioned so that the injection trajectory of the gas is in the plane of the injection trajectory of the liquid.
