Patent number: 11046897Abstract: Methods are provided for performing selective hydrodesulfurization on a naphtha boiling range stream naphtha boiling range portion of a feed. It has been unexpectedly discovered that hydrodesulfurization with improved octane retention can be performed by using a catalyst that comprises CoMo supported on a catalyst support that includes a zeotype framework. By using a catalyst support including a zeotype framework, an unexpectedly high amount of octane in the naphtha boiling range portion of the hydrodesulfurized effluent is maintained.Type: GrantFiled: May 17, 2019Date of Patent: June 29, 2021Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Chuansheng Bai, Majosefina Cunningham, Gregory R. Johnson, Wenyih F. Lai, Brandon J. O'Neill

Publication number: 20200176795Abstract: Systems and methods are provided for integrating a chemical looping combustion system with molten carbonate fuel cells to provide improved operation of the molten carbonate fuel cells when using the exhaust from a gas turbine or other electrical power generation device as the CO2 source for the MCFC cathodes. This integration can be accomplished by using metal oxide in the chemical looping combustion system to oxidize the anode output flow from the MCFCs. This can reduce or minimize the number of separations that need to be performed in order to process the concentrated CO2 present within the anode exhaust. By reducing, minimizing, or eliminating the CO and H2 in the anode exhaust, the need to perform more costly separations (such as cryogenic separation or amine washing) to obtain a high purity CO2 product stream can be reduced or minimized. Optionally, the cathode exhaust from the molten carbonate fuel cells can be used as an oxygen-containing stream for regeneration of the metal oxide.Type: ApplicationFiled: January 9, 2020Publication date: June 4, 2020Inventor: Gregory R. Johnson

Publication number: 20190291085Abstract: Bulk metallic catalyst precursors are provided that include a Group VIB metal, such as Ni, a Group VIII metal, such as Mo or W, an organic-compound based component, and an organo-metalloxane polymer or gel. The catalyst precursors can further include a binder. Amorphous sulfided catalysts formed from the catalyst precursors are also provided. The catalyst precursor can have a surface area of about 50 m2/g or less.Type: ApplicationFiled: March 18, 2019Publication date: September 26, 2019Inventors: Chuansheng Bai, Majosefina Cunningham, Gregory R.

Publication number: 20180134972Abstract: Systems and methods are provided for upgrading blends of catalytic slurry oil and steam cracker tar to form fuel and/or fuel blending products. The steam cracker tar can optionally correspond to a fluxed steam cracker tar that includes steam cracker gas oil and/or another type of gas oil or other diluent. It has been unexpectedly discovered that blends of catalytic slurry oil and steam cracker tar can be hydroprocessed under fixed bed conditions while reducing or minimizing the amount of coke formation on the hydroprocessing catalyst and/or while reducing or minimizing plugging of the fixed bed, as would be conventionally expected during fixed bed processing of a feed containing a substantial portion of steam cracker tar. Additionally or alternately, it has been unexpectedly discovered that formation of coke fines within steam cracker tar can be reduced or minimized by blending steam cracker tar with catalytic slurry oil.Type: ApplicationFiled: October 23, 2017Publication date: May 17, 2018Inventors: Stephen H. BROWN, Brian A. CUNNINGHAM, Randolph J. SMILEY, Samia ILIAS, Jesse R. McMANUS, Aldrin G. CUEVAS, Teng XU, Gregory R. JOHNSON, John P. GREELEY
