Abstract
This invention relates to a staged-zone reactor of the axial-flow type that makes it possible to implement strongly endothermic or exothermic reactions. The reactor comprises a constriction of the catalytic bed between an upper zone (3a) and a lower zone (3b), making it possible to house in the reactor a heat exchanger for the intermediate heating or cooling of the effluents. Process of chemical conversion using this reactor for exothermic or endothermic reactions in the gas and/or liquid phase, and in particular for the oligomerization reaction of C2 to C12 fractions for the purpose of producing a diesel fraction.
