  • Process for preparing a structurally selective oligomerization catalyst of prolonged stability by precipitation
    Patent number: 10987664
    Abstract: 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.
    Type: Grant
    Filed: March 11, 2019
    Date of Patent: April 27, 2021
    Assignee: Evonik Operations GmbH
    Inventors: Wladimir Reschetilowski, Felix Alscher, Henrik Frenzel, Ekaterina Borovinskaya, Cornelia Breitkopf, Fabian Nadolny, Guido Stochniol, Stephan Peitz, Robert Franke
  • Process for oligomerization of butene with determination of the proportion of acidic catalysis
    Patent number: 10633302
    Abstract: 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.
