Wide-cut synthetic isoparaffinic lubricating oils
A wide-cut lubricant base stock is made by hydroisomerizing and then catalytically dewaxing a waxy Fischer-Tropsch synthesized hydrocarbon fraction feed and comprises the entire dewaxate having an initial boiling point in the 650-75O° F.+ range. Formulated lubricating oils made by admixing the base stock with a commercial automotive additive package meet all specifications, including low temperature properties, for multigrade internal combustion engine crankcase oils. The waxy feed has an initial boiling point in the 650-750° F. range and continuously boils to an end point of at least 1050° F.+. Lower boiling hydrocarbons produced by the process are separated from the base stock by simple flash distillation. The base stock comprises the entire dewaxate having an initial boiling point in the 650-750° F. range.

Effective integration of solvent deasphalting and ebullated-bed processing
InactiveUS7214308B2Reduced light gas yieldImprove hydrogen efficiencyTreatment with plural parallel cracking stages onlyTreatment with plural parallel stages onlyReactor systemHeavy crude oil
This invention relates to a novel method for economically processing vacuum residue from heavy crude oils by selectively processing the difficult and easy components in reactors whose design and operating conditions are optimized for the specific feed. The process utilizes an integrated solvent deasphalting (SDA) / ebullated-bed design wherein the heavy vacuum residue feedstock is initially sent to an SDA unit operated with C4 / C5 solvent to achieve a high deasphalted oil (DAO) yield. The resulting SDA products, namely asphaltenes and DAO are separately treated in ebullated-bed reactor(s) systems whose design and operating conditions are optimized for a particular feedstock. The resulting net conversion, associated distillate yield and product qualities are greatly improved relative to treatment of the entire residue feedstock in a common ebullated-bed reactor system.

This invention relates to a novel integrated method for economically processing vacuum residue from heavy crude oils. This is accomplished by utilizing a solvent deasphalter (SDA) in the first step of the process with a C3 / C4 / C5 solvent such that the DAO product can thereafter be processed in a classic fixed-bed hydrotreater or hydrocracker. The SDA feed also includes recycled stripper bottoms containing unconverted residue / asphaltenes from a downstream steam stripper unit. The asphaltenes from the SDA are sent to an ebullated-bed reactor for conversion of the residue and asphaltenes. Residue conversion in the range of 60-80% is achieved and asphaltene conversion is in the range of 50-70%. The overall residue conversion, with the DAO product considered non-residue, is in the range of 80 W %-90 W % and significantly higher than could be achieved without utilizing the present invention.

Modified thermal processing of heavy hydrocarbon feedstocks
InactiveUS7572362B2Quick upgradeReducing H2S contentThermal non-catalytic crackingTreatment with plural serial cracking stages onlyLiquid productParticulates
The present invention is directed to the upgrading of heavy petroleum oils of high viscosity and low API gravity that are typically not suitable for pipelining without the use of diluents. It utilizes a short residence-time pyrolytic reactor operating under conditions that result in a rapid pyrolytic distillation with coke formation. Both physical and chemical changes taking place lead to an overall molecular weight reduction in the liquid product and rejection of certain components with the byproduct coke. The liquid product is upgraded primarily because of its substantially reduced viscosity, increased API gravity, and the content of middle and light distillate fractions. While maximizing the overall liquid yield, the improvements in viscosity and API gravity can render the liquid product suitable for pipelining without the use of diluents. This invention particularly relates to reducing sulfur emissions during the combustion of byproduct coke (or coke and gas), to reducing the total acid number (TAN) of the liquid product, and to reducing the hydrogen sulfide content of one, or more than one component of the product stream. The method comprises introducing a particulate heat carrier into an up-flow reactor, introducing the feedstock at a location above the entry of the particulate heat carrier, allowing the heavy hydrocarbon feedstock to interact with the heat carrier for a short time, separating the vapors of the product stream from the particulate heat carrier and liquid and byproduct solid matter, regenerating the particulate heat carrier in the presence of the calcium compound, and collecting a gaseous and liquid product from the product stream.

Hydrogen donor solvent production and use in resid hydrocracking processes
InactiveUS20070108100A1Treatment with plural serial cracking stages onlyCoke ovensHydrogenBoiling point
A process derived hydrogen donor solvent is used to increase the maximum resid conversion and conversion rate in an ebullated bed resid hydrocracker. The hydrogen donor solvent precursor is produced by hydroreforming reactions within the resid hydrocracker, recovered as the resin fraction from a solvent deasphalting unit, regenerated in a separate hydrotreater reactor, and recycled to the ebullated bed resid hydrocracker. The major advantage of this invention relative to earlier processes is that hydrogen is more efficiently transferred to the resin residual oil in the separate hydrotreater and the hydrogen donor solvent effectively retards the formation of coke precursors at higher ebullated bed resid hydrocracker operating temperatures and resid cracking rates.

Feed oil is subject to atmospheric distillation, to thereby be separated into light oil or light distillate and atmospheric residue oil. The light distillate is catalytically contacted with pressurized hydrogen in the presence of a catalyst, resulting in a first hydrotreating step being executed. In this instance, various fractions of the light distillate produced in the atmospheric distillation are subject to hydrotreating in a lump. The atmospheric residue oil is then separated into a light matter and a heavy matter. The light matter is subject to second hydrotreating in the presence of a catalyst to produce refined oil (light matter), which is mixed with refined oil produced in the first hydrotreating to prepare a mixture. The mixture is used as gas turbine fuel oil.

A new residuum full hydroconversion slurry reactor system has been developed that allows the catalyst, unconverted oil, products and hydrogen to circulate in a continuous mixture throughout an entire reactor with no confinement of the mixture. The mixture is partially separated in between the reactors to remove only the products and hydrogen while permitting the unconverted oil and the slurry catalyst to continue on into the next sequential reactor. In the next reactor, a portion of the unconverted oil is converted to lower boiling point hydrocarbons, once again creating a mixture of unconverted oil, products, hydrogen and slurry catalyst. Further hydroprocessing may occur in additional reactors, fully converting the oil. The oil may alternately be partially converted, leaving a highly concentrated catalyst in unconverted oil which can be recycled directly to the first reactor. The slurry reactor system is, in this invention, preceded by an in-line pretreating step, such as hydrotreating or deasphalting. Following the slurry reactor system, fully converted oil may be subsequently hydrofinished for the removal of hetoroatoms such as sulfur and nitrogen.

The present invention is directed to the upgrading of heavy hydrocarbon feedstock that utilizes a short residence pyrolytic reactor operating under conditions that cracks and chemically upgrades the feedstock. The process of the present invention provides for the preparation of a partially upgraded feedstock exhibiting reduced viscosity and increased API gravity. This process selectively removes metals, salts, water and nitrogen from the feedstock, while at the same time maximizes the yield of the liquid product, and minimizes coke and gas production.
