In a method for preparing a heterogeneous catalyst comprising rhenium as an active ingredient and an inert carrier medium, before supplying the active ingredient onto the inert carrier, the carrier is pretreated with a silanized compound containing chlorine, and subjected to heat treatment. A method is described which is characterized in that after the heterogeneous catalyst has been activated, it is finally cooled rapidly. The catalyst is particularly active in olefin metathesis reactions. |
