  • Oligomerisation of olefinic compounds with reduced polymer formation
    Patent number: 9447202
    Abstract: A process for oligomerization of an olefinic compound for producing an oligomeric product is carried out in the presence of an activated catalyst, a non-metal oxygen containing additive and optionally a zinc compound. The oligomerization catalyst is an activated catalyst, which is provided by combining a source of chromium, a ligating compound, and a catalyst activator or combination of catalyst activators. The non-metal oxygen containing additive is present in an amount such that the ratio of the molar amount of the non-metal oxygen containing additive to the molar amount of chromium in the source of chromium per 106 g/g Cr productivity is between 0.01 and 400.
    Type: Grant
    Filed: May 8, 2013
    Date of Patent: September 20, 2016

  • Oligomerisation of olefinic compounds with reduced polymer formation
    Patent number: 8859696
    Abstract: A process for producing an oligomeric product by oligomerization of at least one olefinic compound, the process including a) providing an activated oligomerization catalyst, by combining, in any order, i) a source of chromium, ii) a ligating compound, iii) a catalyst activator or combination of catalyst activators, b) providing a zinc compound, and c) contacting the at least one olefinic compound with a composition containing the activated oligomerization catalyst and the zinc compound, the zinc compound being present in a sufficient quantity such that the ratio of the molar amount of zinc in the zinc compound to the molar amount of chromium in the source of chromium is between 1 and 10,000. The invention also provides a process of activating an oligomerization catalyst to be used to produce an oligomeric product from at least one olefinic compound.
