A process for preparing an oligomerization catalyst is based on using nickel aluminosilicate that has high activity and selectivity coupled with adequate service life in the heterogeneously catalysed oligomerization of C3 to C6 olefins or olefin-containing feed mixtures based thereon.

Process for preparing a structurally selective oligomerization catalyst of prolonged stability by precipitation

The present invention relates to an oligomerization catalyst for oligomerization of low-molecular-weight olefins, to the use of said catalyst and to a process for oligomerization of low-molecular-weight olefins using the oligomerization catalyst according to the invention.

Ni-containing catalyst for the oligomerization of olefins

The invention provides a process for oligomerization of n-butenes using a nickel-containing aluminosilicate catalyst to produce a product mixture whose ratio of 4,4-dimethylhexene to 3,4-dimethylhexene is determined and monitored. The invention further relates to a process for determining the ratio of the amount of the formed 4,4-dimethylhexene or of the formed 3-ethyl-2-methylpentene to the amount of the formed 3,4-dimethylhexene.
