Abstract (en)
[origin: CA3202284A1] The present invention relates to a gas/liquid reactor for oligomerising gaseous ethylene, comprising a central duct defining, inside the enclosure of the reactor, a downward-flow central area and an upward-flow outer area, thereby increasing the travel time of the gas bubbles injected into the liquid phase, without increasing the volume of the liquid phase and consequently the volume of the reactor.
