Patent number: 10583425Abstract: Systems and methods are provided for activation of noble metal catalysts that are supported on siliceous supports. The activation method can include limiting the amount of water vapor pressure and/or the time of exposure to the water vapor pressure during heating of the catalyst at temperatures of 50° C. or less. This can be achieved by introducing heated gas into multiple reactors of a multi-reactor system at the same time. A suitable system for introducing heated gas into multiple reactors can correspond to a system with multiple heated hydrogen lines for delivery of heated hydrogen to a plurality of reactors within a multi-reactor system.Type: GrantFiled: July 18, 2018Date of Patent: March 10, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Stephen J.

Patent number: 10550341Abstract: Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.Type: GrantFiled: December 27, 2016Date of Patent: February 4, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Mohsen N. Harandi, Doron Levin, Himanshu Gupta, James R. Lattner, Glenn C. Wood, Keith K. Aldous, Timothy L. Hilbert, Michael B. Carroll, Ajit B. Dandekar, Sara L. Yohe, Stephen H. Brown, Tracie L.

Publication number: 20190218465Abstract: Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. The separate processing can allow for selection of conditions for forming lubricant fractions, such as bright stock fractions, that have a cloud point that is lower than the pour point.Type: ApplicationFiled: March 20, 2019Publication date: July 18, 2019Inventors: Kendall S.

Patent number: 10053638Abstract: Methods are provided for dewaxing a distillate fuel boiling range feed to improve one or more cold flow properties of the distillate fuel feed, such as cloud point, with reduced consumption of hydrogen during the dewaxing process. The reduced hydrogen consumption is achieved by using a dewaxing catalyst with a reduced content of hydrogenation metals, such as a content of Pt or Pd of from about 0.03 wt % to about 0.35 wt %. A distillate fuel feed can be dewaxed to achieve a desired cloud point differential using a reduced metals content dewaxing catalyst under the same or similar conditions to those required for a dewaxing catalyst with higher metals content.Type: GrantFiled: February 28, 2014Date of Patent: August 21, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Xiaochun Xu, William J.

Patent number: 10000712Abstract: A method for producing diesel fuel from biocomponent feeds includes hydrotreating the feed followed by catalytic dewaxing with a 1-D, 10 member ring molecular sieve containing catalyst. The hydrotreated feed may be cascaded directly to the dewaxing step, or the hydrotreated feed can undergo intermediate separation. The diesel fuel resulting from processing of the biocomponent feed exhibits superior cetane values.Type: GrantFiled: June 8, 2016Date of Patent: June 19, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: William J.

Patent number: 9964256Abstract: In a process for the catalytic conversion of organic oxygenates to hydrocarbons, a feed comprising at least one organic oxygenate is contacted with a zeolite catalyst under conditions effective to produce a hydrocarbon product comprising aromatics, olefins and paraffins. At least a fraction of the hydrocarbon product containing C4+ hydrocarbons, including at least part of the olefins, is then contacted with hydrogen in the presence of a hydrogenation catalyst under conditions effective to saturate at least part of the olefins in the C4+-containing fraction and produce a hydrogenated effluent containing less than 1 wt % olefins. The hydrogenated effluent is useful as a diluent for heavy crude oils.Type: GrantFiled: December 8, 2015Date of Patent: May 8, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Mohsen N.

Patent number: 9719034Abstract: Methods are provided for processing a gas oil boiling range feedstock, such as a vacuum gas oil, in a single reaction stage and/or without performing intermediate separations. The methods are suitable for forming lubricants and distillate fuels while reducing or minimizing the production of lower boiling products such as naphtha and light ends. The methods can provide desirable yields of distillate fuels and lubricant base oils without requiring separate catalyst beds or stages for dewaxing and hydrocracking. The methods are based in part on use of a dewaxing catalyst that is tolerant of sour processing environments while still providing desirable levels of activity for both feed conversion and feed isomerization.Type: GrantFiled: November 18, 2014Date of Patent: August 1, 2017Assignee: ExxonMobil Research and Engineering CompanyInventors: Stuart S. Shih, Gary P. Schleicher, Michael B. Carroll, Timothy L. Hilbert, Stephen J. McCarthy, William J. Novak
