    Abstract: Non-coordinating anions or anion precursors are disclosed. These non-coordinating anions serve as the activator for olefin polymerization catalyst systems. As such, they abstract an alkyl leaving group from a metallocene catalyst precursor leaving an activated catalyst charge balanced by a non-coordinating anion. These anions are formed by 3 or 4 partially fluorinated naphthyl ligands coordinated around boron (or other Group-13 element) creating corresponding tris-borane or tetrakis-borate complexes.

  • Patent number: 7253135
    Abstract: A silicon-containing alumina support, a process for preparing the support, and a catalyst containing the support are provided. The alumina support includes an additive silicon enriched on its surface, with the difference between the atomic ratio of silicon to aluminum on the surface of alumina support and that of the alumina support is at least 0.10. The process for preparing the silicon-containing alumina support comprises adding a nanometer silicon compound. The inventive alumina support can be used in manufacturing a catalyst for hydrotreating hydrocarbons with good physico-chemical properties and performance.

  • Patent number: 7157401
    Abstract: A catalyst for the hydroprocessing of organic compounds, composed of an interstitial metal hydride having a reaction surface at which monatomic hydrogen is available. The activity of the catalyst is maximized by avoiding surface oxide formation. Transition metals and lanthanide metals compose the compound from which the interstitial metal hydride is formed. The catalyst's capabilities can be further enhanced using radio frequency (RF) or microwave energy.
