PREPARAZIONE DI UN CATALIZZATORE SUPPORTATO A BASE DI RENIO E SUO IMPIEGO NELLA REAZIONE DI METATESI DI OLEFINE

摘要

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.
