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: 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.

Abstract: A process for upgrading oil feedstock wherein the feedstock is hydrotreated, hydrocracked, and flashed and/or distilled. The bottoms are then vacuum distilled to adjust viscosity and volatility. The refined feed is then extracted, dewaxed, and cascaded to a hydrofinishing step, where it is contacted with a catalyst having a metal hydrogenation function in order to produce lubricant products.

Abstract: A process for upgrading a hydrocarbon oil is provided which comprises introducing the oil and an aromatic extraction solvent containing 0.1 to 10 vol % water into an extraction zone for contact of the oil and solvent therein whereby an extract solution is formed; and injecting water into the extraction zone at a point below that at which the extraction solvent is introduced. The injected water is injected substantially countercurrent to the extraction solvent at a velocity of about 0.5 to 3 ft/sec in an amount ranging from about 0.1 to about 10 LV% based on the amount of extract solution being processed.

Abstract: A method for removing corrosive contaminants from a polar extraction solvent comprises adding water to the solvent to provide a mixture. Then the mixture is contacted with a basic ion exchanger resin to remove the corrosive contaminants. The solvent is recovered and may be reused.

Abstract: A method for producing a process oil in which a naphthenic rich distillate is processed through a single hydrotreating stage, the hydrotreated distillate is then solvent extracted to yield a process oil which passes IP-346 and AMES screening test.

Abstract: The present invention is directed to an improved selective solvent extraction process wherein a hydrocarbon feed stream containing a mixture of aromatics and non-aromatics is contacted with an aromatics selective solvent in an extraction zone to produce an aromatics rich extract phase and an aromatics lean raffinate phase, water in a carefully controlled amount is added to the recovered extract phase resulting in the separation of the extract phase into a hydrocarbon rich pseudo-raffinate which is recycled to the extraction zone for processing with fresh feed and an increased yield of raffinate of higher quality than is obtained without pseudo-raffinate recycle.

Abstract: The presence of carryunder in the extract phase recovered from a solvent extraction tower is an indication of unsatisfactory performance. The continuous analysis of the extract phase using a turbidity analyzer to detect the presence of two phases, indicating carryunder permits corrective measures to be taken in tower operation to reduce or eliminate carryunder.

Abstract: An alkylation process which utilizes a solid alkylation catalyst is disclosed. The catalyst, which has carbonaceous material adsorbed thereto, is regenerated by reacting the adsorbed carbonaceous material. The reaction step is accomplished by heating the catalyst in the presence of ozone to form an ozonated hydrocarbon, wherein the ozonated hydrocarbon includes carbonyl carbons. The ozonated hydrocarbon is removed by desorbing the carbonyl carbons from the solid alkylation catalyst. The carbonaceous material is preferably reacted at a temperature ranging from about 20.degree. C. to 200.degree. C. The ozone is preferably in a gaseous stream at a concentration ranging from about 1 to 50 volume percent. The carbonyl components are preferably desorbed from the heated alkylation catalyst by sweeping the catalyst with a desorption fluid.

Abstract: Catalytic reforming wherein the lead reactor contains a catalyst comprised of platinum and a relatively low level of Re on an inorganic oxide support. The tail reactor contains a tin modified platinum-iridium catalyst wherein the metals are substantially uniformly dispersed throughout the inorganic oxide support.

Abstract: A process for reforming a naphtha feed at low severities with tin modified platinum-iridium catalysts. In particular, both high selectivity, and high activity are manifested by such catalysts in reforming a naphtha feed at low severities in the lead reactor, or reactors, of a series of reactors; i.e., within the dehydrogenation and ring isomerization zone, or zones, of a reforming unit. The lead reactors of the series are charged with a tin-containing platinum-iridium catalyst, and the naphtha feed reformed to produce a low RON clear C.sub.5 + liquid reformate. The low octane product of the lead reactors may be transferred to a mogas pool, into blending components, or all or some part of the product further reformed. Preferably, the product is further reformed in a tail reactor, and preferably the tail reactor is charged with a non-tin containing platinum, or platinum-iridium catalyst.

Abstract: Tin modified platinum-iridium catalysts provide high yields of C.sub.5 +liquid reformate in catalytic reforming, concurrent with high activity. In particular, the tin modified platinum-iridium catalysts are of unusually high selectivity, as contrasted with known iridium promoted platinum catalysts. The high selectivity is manifested in reforming a naphtha feed in a reactor charged to capacity with the catalyst, but particularly when used in the dehydrocyclization zone, or tail reactor of a series of reactors, while the lead reactors of the series contain a non tin-containing platinum catalyst, especially a platinum-iridium, or a platinum-rhenium catalyst. The tin modified platinum-iridium catalysts are also highly active, with only moderate loss in the high activity for which iridium stabilized platinum catalysts are known.

Abstract: A process for the regeneration of a coked platinum, or polymetallic platinum reforming catalyst with ozone. The coked catalyst is contacted, and carbon burned from the catalyst at temperatures ranging from about 20.degree. C. to 200.degree. C., preferably about 60.degree. C. to 150.degree. C., with a gaseous stream containing ozone in concentration ranging from about 1 to 50 volume percent ozone sufficient to substantially deplete said catalyst of sufficient carbon to restore the activity of the catalyst to that of the corresponding fresh catalyst.

Abstract: A catalytic reforming process in which sulfur moieties are removed from a gaseous product stream by use of a sulfur trap comprised of about 10 to about 70 wt. % nickel dispersed on a support. The sulfur which is removed is both sulfur which is inherent in the feed as well as sulfur which results from presulfiding the catalyst.
