Patent number: 10047299Abstract: Systems and methods are provided for upgrading catalytic slurry oil to form naphtha boiling range and/or distillate boiling range fuel products. It has been unexpectedly discovered that catalytic slurry oil can be separately hydroprocessed under fixed bed conditions to achieve substantial conversion of asphaltenes within the slurry oil (such as substantially complete conversion) while reducing or minimizing the amount of coke formation on the hydroprocessing catalyst. After hydroprocessing, the hydroprocessed effluent can be processed under fluid catalytic cracking conditions to form various products, including distillate boiling range fuels and/or naphtha boiling range fuels. Another portion of the effluent can be suitable for use as a low sulfur fuel oil, such as a fuel oil having a sulfur content of 0.1 wt % or less.Type: GrantFiled: June 30, 2016Date of Patent: August 14, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Sheryl B. Rubin-Pitel, Kenneth C. H. Kar, Stephen H. Brown, Federico Barrai, Brian A. Cunningham

Patent number: 9677015Abstract: Systems and methods are provided for processing a heavy oil feed, such as an atmospheric or vacuum resid, using a combination of solvent assisted hydroprocessing and slurry hydroconversion of a heavy oil feed. The systems and methods allow for conversion and desulfurization/denitrogenation of a feed to form fuels and gas oil (or lubricant base oil) boiling range fractions while reducing the portion of the feed that is exposed to the high severity conditions present in slurry hydroconversion.Type: GrantFiled: June 19, 2014Date of Patent: June 13, 2017Assignee: ExxonMobil Research and Engineering CompanyInventors: Himanshu Gupta, Stephen Harold Brown, Federico Barrai, Kirtan Kunjbihari Trivedi

Publication number: 20170022433Abstract: Systems and methods are provided for fixed bed hydroprocessing of deasphalter rock. Instead of attempting to process vacuum resid in a fixed bed processing unit, vacuum resid is deasphalted to form a deasphalted oil and deasphalter residue or rock. The rock can then be hydroprocessed in a fixed bed reaction zone, optionally after combining the rock with an aromatic co-feed and/or a hydroprocessing solvent. This can allow for improved conversion of the deasphalter rock and/or improved combined conversion of the deasphalter rock and deasphalted oil.Type: ApplicationFiled: July 6, 2016Publication date: January 26, 2017Inventors: Stephen H. BROWN, Warren B. AMES, Federico BARRAI

Publication number: 20160298048Abstract: Methods are provided for processing deasphalted gas oils derived from thermally cracked resid fractions to form Group I, Group II, and/or Group III lubricant base oils. The yield of lubricant base oils (optionally also referred to as base stocks) can be increased by thermally cracking a resid fraction at an intermediate level of single pass severity relative to conventional methods. By performing thermal cracking to a partial level of conversion, compounds within a resid fraction that are beneficial for increasing both the viscosity and the viscosity index of a lubricant base oil can be retained, thus allowing for an improved yield of higher viscosity lubricant base oils from a thermally cracked resid fraction.Type: ApplicationFiled: April 12, 2016Publication date: October 13, 2016Inventors: Stephen H. Brown, Brenda A. Raich, Beatrice M. Gooding, Stephen M. Davis, Federico Barrai, Warren B. Ames, Keith K. Aldous
