Patent number: 6444866Abstract: 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 (Cn) is introduced via line 1 into a reaction zone R1 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 2 to a heat exchanger E1 traversed by a cold liquid. The effluent is thus cooled before being sent via line 3 to a second reaction zone R2 where it undergoes catalytic oligomerisation in a liquid-liquid two-phase medium. After reaction, the effluent is fed via line 4 to a zone L1 where it is washed. After washing, the hydrocarbon fraction is sent via line 5 to separator S1.Type: GrantFiled: July 6, 1998Date of Patent: September 3, 2002Assignee: Institut Francais du PetroleInventors: Dominique Commereuc, Alain Forestiere, François Hughes, Hélène Olivier-Bourbigou

Publication number: 20020052537Abstract: A process is described for carrying out olefin oligomerisation in two catalysis steps of different types, using an organic feed containing at least one olefin. The cut to be treated, containing at least one olefin (Cn), is introduced into a first reaction zone where, in a first step, it undergoes catalytic oligomerisation either of the homogeneous liquid phase type, or of the heterogeneous type with a solid support. The effluent produced is generally sent to a heat exchanger traversed by a cold liquid, the effluent thus being cooled before being sent to a second reaction zone where it undergoes catalytic oligomerisation in a liquid-liquid two-phase medium, the invention being characterized in that at least an ethylenic hydrocarbon containing 3 to 5 carbon atoms per molecule is added to the inlet to the second reaction zone.Type: ApplicationFiled: October 26, 2001Publication date: May 2, 2002Applicant: Institut Francais du PetroleInventors: Dominique Commereuc, Alain Forestiere, Francois Hugues, Helene Olivier-Bourbigou

Patent number: 6284937Abstract: A process for carrying out a reaction on an organic feed, for example dimerization, co-dimerization, oligomerization or metathesis of olefins, as described in which the catalyst is a catalytic metal compound dissolved in a non-aqueous ionic medium which is not or is only slightly miscible with hydrocarbons. The reaction is carried out in a system comprising at least two treatment loops each comprising at least one reaction zone and at least one zone for separating the organic and polar phases between which the polar medium containing the catalytic metal compound, and the organic phase circulate. Fresh polar phase is injected into the second loop and used polar phase is eliminated from the first loop.

The invention also concerns a unit for carrying out the process.Type: GrantFiled: May 27, 1998Date of Patent: September 4, 2001Assignee: Institut Francais du PetroleInventors: Helene Olivier, Dominique Commereuc, Alain Forestiere, Francois Hugues
