  • Heat management in ethylene oligomerization
    Patent number: 10160696
    Abstract: The oligomerization of ethylene using a chromium catalyst having a heteroatomic ligand may be used to provide oligomerization products that are selective towards hexene and/or octene. However, such processes also typically produce some polymer as an undesirable by product. The present invention is directed towards improvements in the selective oligomerization of ethylene.

  • Reactor continuity
    Patent number: 9115224
    Abstract: A supported catalyst system comprising a phosphinimine ligand containing catalyst on an alumina support treated with a metal salt has improved reactor continuity in a dispersed phase reaction in terms of initial activation and subsequent deactivation. The resulting catalyst has a lower consumption of ethylene during initiation and a lower rate of deactivation. Preferably the catalyst is used with an antistatic agent.

  • Reactor continuity
    Patent number: 8846811
    Abstract: A dual catalyst system comprising a phosphinimine ligand containing catalyst and phenoxide ligand (preferably a salicylaldimine) on a support treated with a metal salt has improved reactor continuity in a dispersed phase reaction in terms of initial activation and subsequent deactivation The resulting catalyst has a lower consumption of ethylene during initiation and a lower rate of deactivation. Preferably the catalyst is used with an antistatic agent.

  • Reactor continuity
    Patent number: 8298978
    Abstract: Single site reactor/catalyst continuity in a dispersed phase reaction in terms of initial activation and subsequent deactivation may be improved by treating the support with a metal salt. The activator and catalyst are then deposited on the treated support. The resulting catalyst has a lower consumption of ethylene during initiation and a lower rate of deactivation. Preferably the catalyst is used with an antistatic agent.

  • Activation for Oligomerization
    Publication number: 20120271087
    Abstract: The oligomerization of ethylene using a chromium catalyst and an aluminoxane activator is well known. The undesired formation of polyethylene as a by-product is also known to occur during prior oligomerization processes. We have discovered that the use of an aluminoxane that is prepared by non-hydrolytic means provides a highly productive activator (co-catalyst) for ethylene oligomerization and mitigates the undesired formation of by-product polyethylene.

  • Polymer mitigation
    Publication number: 20110257350
    Abstract: Ethylene is selectively oligomerized in a continuously stirred tank reactor (CSTR) that is preferably operated in an isothermal manner using a chromium catalyst. The undesired formation of by-product polyethylene is mitigated by contacting the ethylene with hydrogen prior to adding the ethylene to the reactor and feeding the ethylene and hydrogen via a common feed port.
