International Classification:

C10G 7302

US Classification:

208 87, 208 18, 208 27, 208 28, 208 33, 208 86, 208133

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.

US Classification:

208210, 208 89, 208 91, 208143, 208212, 208213, 208217

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 ânilâ 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 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.

International Classification:

C10G 65/02
C10G 73/38

US Classification:

208 89, 208 27, 208108

Abstract:

A process for preparing high VI lubricating oil basestocks comprising hydrotreating, hydrodewaxing and optionally hydrofinishing. The hydrotreated feedstock is hydrodewaxed using a dewaxing catalyst that has been selectively activated by oxygenate treatment. The hydrodewaxed product may then be hydrofinished.

US Classification:

208 58, 208 59, 208 27, 20811135, 208 89

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.

International Classification:

B01J 29/06

US Classification:

502 64, 502 77, 502 79

Abstract:

A dewaxing catalyst is selectively activated by treatment with an oxygenate. Selective activation is accomplished by treated the dewaxing catalyst with a carrier feed containing oxygenate. The selectively activated dewaxing catalyst when used to dewax waxy hydrocarbons results in improved yield of isomerate at equivalent pour point over a dewaxing catalyst which has not been oxygenate treated.

Abstract:

A waxy hydrocarbon feed is catalytically treated with a dewaxing catalyst that has been selectively activated. The selective activation of the catalyst involves treating the catalyst with at least one oxygenate. The selectively activated catalyst can then be used to dewax waxy hydrocarbon to improve yield and product quality of the isomerate product.
