Abstract

The present invention relates to a process for isomerizing linear alpha-olefins having from 4 to 8 carbon atoms over a heterogeneous catalyst, wherein the catalyst comprises a hydrogenation metal and a selectivity promoter selected from among selenium and tellurium on a support, and also a process for preparing 1-olefins by a metathesis reaction of 2-olefins with ethene, wherein the 2-olefins are prepared by the above mentioned isomerization process.
