Abstract

The present invention relates to a process for obtaining an olefin by metathesis including the steps of i) feeding at least one stream with at least one olefin as starting material to at least one first reactor with at least one pre-bed having at least one compound selected from the group of alkaline earth oxides and ii) feeding the stream leaving the at least one first reactor to at least one second reactor downstream to the at least one first reactor including at least one main bed having a) at least one first catalyst component and b) at least one second catalyst component. The first and second catalyst are physically mixed with each other. The operational temperature of the at least one first reactor is lower than the operational temperature of the at least one second reactor.
