    摘要: The present invention is directed to an improved isomerization process employing a catalyst wherein the catalyst comprises a pair of catalyst particles of different acidity utilized either as distinct beds of such discrete particles or as a mixture of such discrete particles. The isomerization process utilizing such a catalyst produces a product which exhibits higher VI as compared to products produced using either catalyst component separately or using a single catalyst having the average acidity of the two discrete catalysts.

    摘要: A three stage process for producing high quality white oils, particularly food grade mineral oils from mineral oil distillates. The first reaction stage preferably 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 preferably employs a hydrogenation/hydrodesulfurization catalyst combined with a sulfur sorbent and produces 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 grade white oil.

    摘要: An improved catalyst for the production of lube oil blending components, and lube oils, from waxy, paraffinic feeds, a process for producing such catalyst, and a process utilizing this catalyst in the production of lubes. The catalyst is a unitized mixed powder pellet catalyst constituted of a dehydrogenation component, or components, suitably a catalytically active Group VIB, VIIB, or VIII metal, or metals, an isomerization component, suitably an amorphous acidic solid support, and a small pore molecular sieve dewaxing component. The dewaxing component is characterized as a small pore molecular sieve wherein the pore windows are formed by 8 oxide atoms which form the limiting edge of the pore window, each of the oxide atoms constituting one of the four oxide atoms of a tetrahedrally coordinated cluster around a silicon or aluminum framework ion, or atom, each oxide ion is coordinated to two framework ions in these structures, and the pore size of the sieve ranges between about 6.3 .ANG. and 2.3 .ANG.. In preparation of the catalysts, the isomerization component, or the dewaxing component, or both, may provide the dehydrogenation function due to the presence of a catalytic metal, or metals, deposited thereon, in which case the components are powdered, the powders mixed together, compressed and formed into solids catalyst shapes comprised of these components. Alternatively, the dehydrogenation function can be added to preformed solids shapes made from powdered dewaxing and isomerization components.
