Reactor continuity

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 o...

More Information
Summary: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.
