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

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.

The invention is directed to a process for the preparation of lubricant base stocks by contacting alphaolefin feedstocks with single-site metallocene catalysts and recycling unconverted monomers, characterized by a purge step in the recycle.

Utilization of linear alpha olefins in the production of metallocene catalyzed poly-alpha olefins

Methods and apparatus for producing alcohols from syngas are disclosed herein. In some variations, syngas is catalytically converted to alcohols. The alcohols can be subjected to drying to produce an intermediate alcohol product, followed by distilling the intermediate product to produce a purified ethanol product for use in liquid fuels.

Methods and apparatus for producing alcohols from syngas

This invention relates to a polyalpha-olefin (and hydrogenated analogs thereof) comprising more than 50 mole % of one or more C5 to C24 alpha-olefin monomers where the polyalpha-olefin has: a) 40 mole % or more of mm triads, b) a Bromine number of Y or greater, where Y is equal to 89.92*(V)'&#xb0;5863, where V is the Kinematic Viscosity of the polyalpha-olefin measured at 100&#xb0; C. in cSt, and c) 1,2 disubstituted olefins present at 7 mole % or more, preferably having Z mole % or more of units represented by the formula: where j, k and m are each, independently, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, or 22, n is an integer from 1 to 350, and where Z=8.420*Log(V)&#x2212;4.048, where V is the kinematic viscosity of the polyalpha-olefin measured at 1000 C in cSt This invention also relates to process to produce such polyalpha-olefins. 

Polyalpha-olefin compositions and processes to produce the same

The present invention provides a process for producing gasoline components from syngas. Syngas is converted to one or more of methanol, ethanol, mixed alcohols, and dimethyl ether, followed by various combinations of separations and reactions to produce gasoline components with oxygenates, such as alcohols. The syngas is preferably derived from biomass or another renewable carbon-containing feedstock, thereby providing a biorefining process for the production of renewable gasoline.

Process for producing renewable gasoline, and fuel compositions produced therefrom

The present invention provides processes for selectively producing ethanol from syngas. In some variations, the process comprises converting biomass-derived syngas to dimethyl ether, carbonylating the dimethyl ether to methyl acetate, hydrogenating the methyl acetate to methanol and ethanol, and recovering the ethanol product. The methanol is preferably recycled by converting to hydrogen and carbon monoxide for introduction back into the process at distinct points. In certain variations of this invention, fresh syngas feed is introduced downstream of the first unit operation in the sequence. High yields of ethanol from biomass can be achieved according to the disclosed processes.

Selective process for conversion of syngas to ethanol

This invention features methods and apparatus for producing syngas from any carbon-containing feed material. In some embodiments, a substoichiometric amount of oxygen is used to enhance the formation of syngas. In various embodiments, both oxygen and steam are added during the conversion of the feed material into syngas. The syngas can be converted to alcohols, such as ethanol, or to other products.

The invention is directed to a process for producing polyolefins by one or more homogeneous or colloidal polymerization catalyst wherein residual catalyst is removed by using a solid sorbent.

Process to produce polyolefins using metallocene catalysts

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.
