Abstract
A process for oligomerising olefins in an organic feed containing at least one olefin comprises two steps with different types of catalysis. The cut to be treated containing at least one olefin (C ) is introduced via line into a reaction zone R where in a first step it undergoes catalytic oligomerisation, either of a liquid phase homogeneous type, or heterogeneous with a solid support. The effluent produced is sent via line to a heat exchanger E traversed by a cold liquid. The effluent is thus cooled before being sent via line to a second reaction zone R where it undergoes catalytic oligomerisation in a liquid-liquid two-phase medium. After reaction, the effluent is fed via line to a zone L where it is washed. After washing, the hydrocarbon fraction is sent via line to separator S . The fraction containing the unreacted olefins (C ) is separated from the oligomer product fraction produced, this fraction C is evacuated from the apparatus via line , and the fraction containing the oligomer products is evacuated via line
