Abstract
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 The hydrocarbon to be transformed is injected into the first loop and the products are withdrawn from the second loop. The invention also concerns a unit for carrying out the process.
