ABSTRACT:
The present invention relates to embodiments for a process for the isomerization of at least one alpha olefin to an internal olefin via a multi-step process resulting in a mixture comprising alkene isomers and a low level of oligomers. According to the present invention an alkylaluminum compound is used in combination with the Group VIII transition metal salt for interaction with the latter, and thereby generating catalytically active species for the isomerization of 1-alkenes to internal alkenes, wherein this mixture is subsequently combined with an acid washed clay.
