Abstract
A process is described for the preparation of a heterogeneous catalyst containing rhenium as active component and an inert carrier, characterized in that said inert carrier is previously subjected to thermal treatment before the supporting of the active component and the activation of the heterogeneous catalyst is effected by means of thermal treatment followed by a rapid final cooling. The catalyst is particularly active in the metathesis reaction of olefins.

A process for the preparation of a heterogeneous catalyst active in the metathesis reaction of olefins, containing rhenium as active component and an inert carrier, characterized in that the inert carrier is subjected to a thermal treatment at a temperature ranging from 100 to 600° C., in flowing air, before being supported with the active component, and the activation of the heterogeneous catalyst is effected by thermal treatment followed by a final cooling carried out over a time ranging from 5 to 30 minutes.
