ABSTRACT:
The invention provides a catalytic method for the dimerization or codimerization or oligomerization, in particular selective, of olefins, carried out under pressure, in a reaction zone 1 containing a solid catalyst bed in which is disposed a plurality of hollow internal spaces 6.3a defined by walls, each being divided into an upper semi-space 6.3, 1a and a lower semi-space 6.3, 2a which communicate together through a connecting zone 6.6a. An autogenous thermoregulation fluid flows, in the form of a sheet, in said hollow internal spaces 6.3a after passing through a central distributing zone 6.1a and distributing zones 6.2a and before passing into collecting zone 6.4a and into a central collecting zone 6.5a.
