  • Patent number: 8097149
    Abstract: Oil soluble catalysts are used in a process to hydrodesulfurize petroleum feedstock having a high concentration of sulfur-containing compounds and convert the feedstock to a higher value product. The catalyst complex includes at least one attractor species and at least one catalytic metal that are bonded to a plurality of organic ligands that make the catalyst complex oil-soluble. The attractor species selectively attracts the catalyst to sulfur sites in sulfur-containing compounds in the feedstock where the catalytic metal can catalyze the removal of sulfur. Because the attractor species selectively attracts the catalysts to sulfur sites, non-productive, hydrogen consuming side reactions are reduced and greater rates of hydrodesulfurization are achieved while consuming less hydrogen per unit sulfur removed.

  • Patent number: 7169727
    Abstract: A pre-catalyst is formed by reacting butylethylmagnesium with an alcohol to form a magnesium alkoxide compound, followed by contacting the magnesium alkoxide compound with a phosphorous compound to form a magnesium alkoxide phosphorous compound mixture. The magnesium alkoxide phosphorous compound mixture is subsequently reacted with TiCl4 to form a MgCl2 support. The MgCl2 support is then contacted with an internal donor while being heated to form a first catalyst slurry, which is then contacted with TiCl4 while being heated to form a second catalyst slurry. The second catalyst slurry is next contacted with TiCl4 while being heated to form a third catalyst slurry, which is washed and dried, resulting in a highly active pre-catalyst with controlled morphology. The pre-catalyst may be combined with one or more co-catalysts and optionally one or more external electron donors to form an active catalyst system, which may be used for the polymerization of olefins.

  • Patent number: 7148302
    Abstract: This invention is based upon the discovery that a catalyst system which is comprised of (a) palladium or a palladium compound and (b) a fluorinated alcohol is effective for polymerizing norbornene-functional monomers into polynorbornene-functional polymers. It has been further discovered that this catalyst system is more effective in polymerizing certain norbornene-functional monomers that are difficult to polymerize, such as norbornene ester monomers, than prior art catalyst systems. The activity of the catalyst systems of this invention can be further improved with respect to polymerizing some monomers by including a Lewis acid and/or a ligand, such as a phosphine or a carbene, in the system. In any case, the catalyst systems of this invention offer the advantage of being soluble in a wide variety of solvents, relatively inexpensive, and capable of polymerizing many norbornene-functional monomers that are difficult to polymerize with conventional catalyst systems.
