Abstract
The present invention provides a process for converting olefinic C,cuts by metathesis using an improved catalyst containing rhenium, cesium, and delta alumina. The preferred catalysts contains at least one rhenium compound deposited on a support principally composed of alumina, treated at a temperature of more than 750° C., and modified by at least one cesium compound. Thus the duration of the cycle between two regeneration operations is substantially increased.
