| 20090240012 | Process for synthetic lubricant production - A process for the preparation of oligomeric poly alpha-olefins includes oligomerizing low molecular weight PAO oligomer in the presence of a Lewis acid catalyst such as promoted aluminum trichloride or boron trifluoride under oligomerization conditions. The low molecular weight PAO oligomers used as a feed or feed component of the present process are the light olefinic by-product fractions including the dimers and light fractions from the metallocene-catalyzed PAO oligomerization process which are characterized by a molecular weight of 150 to 600 and a terminal olefin (vinylidene) content of at least 25%. | 09-24-2009 |
| 20090247442 | Production of Shear-Stable High Viscosity PAO - The invention is directed to a process for the preparation of high viscosity lubricant base stocks by contacting alphaolefin feedstocks with single-site metallocene catalysts in a mixed flow or continuous stirred tank reactors. | 10-01-2009 |
| 20090326296 | Manufacture of Low Viscosity Poly Alpha-Olefins - The present invention relates to poly alpha-olefins (PAO's) which exhibit superior Noack volatility at low pour points. The poly alpha-olefin is prepared from an olefin feed comprised of a blend of octene, decene, and dodecene, the feed comprising at least 10 weight % octene and at least 30 weight % dodecene. The process includes both synthesis and distillation of the olefin and oligomerization olefin. The oligomerized olefin feed yields at least 50% low viscosity PAO having a nominal viscosity at 100° C. of about 4 cSt. | 12-31-2009 |
| 20100152346 | Plasticized Polyolefin Compositions - The present invention relates to plasticized polyolefin compositions comprising a polyolefin and a non-functionalized hydrocarbon plasticizer. | 06-17-2010 |
| 20100292424 | Lubricants from Mixed Alpha-Olefin Feeds - This invention discloses an improved process which employs mixed alpha-olefins as feed over activated metallocene catalyst systems to provide essentially random liquid polymers particularly useful in lubricant components or as functional fluids. | 11-18-2010 |
| 20110137091 | Manufacture of Oligomers from Nonene - In oligomerizing alpha-olefins to produce poly alpha-olefins, the feedstock consists of nonene, or a blend of alpha-olefins comprising nonene. The nonene comprising alpha-olefin feedstock and at least one catalyst are subjected to oligomerization or polymerization conditions in a reactor. Following reaction, the mixture may be subjected to distillations to removed unreacted alpha-olefins and dimers of the alpha-olefins. The resulting product may also be hydrogenated. The final product may also be fractioned to recover at least two fractions of poly alpha-olefins of differing nominal viscosities. | 06-09-2011 |
