Abstract
A reaction device includes staged zones making it possible to implement strongly endothermic or exothermic reactions. The device reduces the differences in catalytic activity between these zones using an addition of fresh or regenerated catalyst at the inlet of each reaction zone and provides an integrated heat exchanger. A process of chemical conversion employs the device for gas-phase and/or liquid-phase exothermic or endothermic reactions, and in particular for the oligomerization reaction of C2 to C12 fractions for the purpose of producing a diesel fraction.
