Abstract: A process for producing a lubricating oil basestock having at least 90 wt. % saturates and a VI of at least 105 by selectively hydroconverting a raffinate from a solvent extraction zone in a two step hydroconversion zone followed by a hydrofinishing zone, and a lubricating oil basestock produced by said process.

Abstract: This invention relates to base stocks and base oils that exhibit an unexpected combination of high viscosity index (130 or greater) and a ratio of measured-to-theoretical high-shear/low-temperature viscosity at −30C or lower and the methods of making them. Specifically, the present invention relates to low-volatility/low-viscosity lubricant base stocks, lubricant base stocks and base oils, formulated lubricant compositions or functional fluids comprising these base stocks and methods of making them. More particularly, this invention relates to lubricant compositions of low-temperature flow capability and low viscosity for passenger car motor lubricants of SAE 0W-XX grade (where XX=40 or lower), methods for optimizing fuel economy using the same, and methods or processes to produce them.

Abstract: A waxy hydrocarbon feed is catalytically dewaxed with a catalyst that has been selectively activated. The selective activation of the catalyst involves contacting the dewaxing catalyst with a feed mixture containing waxy hydrocarbon and at least one oxygenate. The process results in improved catalyst performance resulting in improved yield of isomerate at equivalent pour.

Abstract: A four stage process for producing high quality white oils, particularly food or medicinal grade mineral oils from mineral oil distillates. The first reaction stage employs a sulfur resistant hydrotreating catalyst and produces a product suitable for use as a high quality lubricating oil base stock. The second reaction stage employs a hydrogenation/hydrodesulfurization catalyst. The third stage employs a reduced metal sulfur sorbent producing a product stream which is low in aromatics and which has substantially “nil” sulfur. The final reaction stage employs a selective hydrogenation catalyst that produces a product suitable as a food or medicinal grade white oil.

Abstract: A process for producing a high VI/low volatility lubricating oil basestock and a lubricating oil basestock prepared by said process. The process comprises subjecting the raffinate from a solvent extraction step to a two step, single stage hydroconversion process wherein the first step involves severe hydroconversion of the raffinate followed by a cold hydrofinishing step.
