  • Catalyst composition and methods for its preparation and use in a polymerization process
    Patent number: 6472342
    Abstract: The present invention relates to a catalyst composition and a method for making the catalyst composition of a polymerization catalyst and a carboxylate metal salt. The invention is also directed to the use of the catalyst composition in the polymerization of olefin(s). In particular, the polymerization catalyst system is supported on a carrier. More particularly, the polymerization catalyst comprises a bulky ligand metallocene-type catalyst system.
    Type: Grant

  • Process for deactivating Ziegler-Natta and metallocene catalysts
    Patent number: 5371053
    Abstract: A process for deactivating Ziegler-Natta and metallocene catalysts or catalyst systems "such systems are typically used for olefin polymerization". The process includes heating the active catalyst or catalyst system to a temperature sufficient to drive off volatile constituents, and to form complexes and compounds that are non-reactive or less reactive with ambient air than the active catalyst or catalyst system. The process includes steps for safe deactivation including scrubbing to substantially eliminate corrosive compounds, and burning volatile chemicals in a flare.This process essentially eliminates the production of hazardous classification waste from conventional water catalyst deactivation techniques.
