    摘要: Liquid poly-alpha-olefins having a KV100 of 2 to 6000 cSt, 20 weight percent dimer or less and a viscosity index of 60 or more are obtained by contacting in a reaction zone, in the presence of from 0 to 60 psi hydrogen, C3 to C20 alpha-olefin monomers with a non-coordinating anion activator, a single bridged meso-metallocene transition metal compound having less than about 35 wt % racemic isomer, and a co-activator. The molar ratio of activator to meso-metallocene is from 10:1 to 0.1:1, and the alpha-olefin monomers in the feed components are present in at least 20 wt % or more based upon the weight of the meso-metallocene, non-coordinating anion activator, co-activator, monomers, and solvent or diluent. The productivity of the process is at least 50,000 g of total product per gram of transition metal compound and no more than 5% monomer is converted from olefin to alkane.

    摘要: 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.

    摘要: A process for reducing boron trifluoride usage and emissions associated with PAO manufacture, the process comprising distilling a portion of the crude PAO product containing a boron trifluoride-organic catalyst at a temperature sufficient to cause the boron trifluoride-organic catalyst to dissociate to produce an overhead stream comprising uncomplexed boron trifluoride and an uncomplexed organic catalyst component, contacting the uncomplexed boron trifluoride and uncomplexed organic catalyst component in a condenser column having an internal structure that increases the recombination of the uncomplexed boron trifluoride and uncomplexed organic catalyst component to form a recycle boron trifluoride-organic catalyst.
