Publication number: 20170362514Abstract: Systems and methods are provided for solvent deasphalting of steam cracker tar. The resulting deasphalted oil produced from the steam cracker tar can then be hydroprocessed, such as hydrotreated and/or hydrocracked in a fixed bed reactor. The solvent deasphalting can correspond to a mild or trim deasphalting or can correspond to solvent deasphalting at higher solvent to oil ratios. Performing a trim deasphalting can reduce or minimize the amount of deasphalting residue that is formed as a product from the deasphalting process.Type: ApplicationFiled: May 26, 2017Publication date: December 21, 2017Inventors: Patrick L. Hanks, Anjaneya S. Kovvali, David T. Ferrughelli, Steven Pyl, Sumathy Raman

Publication number: 20170037331Abstract: 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: ApplicationFiled: June 8, 2016Publication date: February 9, 2017Inventors: William J. NOVAK, Zhiguo HOU, William J. TRACY, III, Patrick L. HANKS, Timothy L. Hilbert

Patent number: 9523046Abstract: Methods are provided herein for co-processing of biocomponent feeds as well processing of mineral feeds in a reaction system at hydrogen partial pressures of about 500 psig (3.4 MPag) or less. The methods include using stacked beds of both CoMo and NiMo catalysts. The stacked catalyst beds provided unexpectedly high catalyst activity as the input feed to a reaction system was switched between a mineral feed and a feed containing both mineral and biocomponent portions. Additionally, use of stacked catalyst beds can allow for maintenance of the activity for the catalyst system in a reaction system while still achieving a desired activity for both types of feeds.Type: GrantFiled: December 5, 2013Date of Patent: December 20, 2016Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Joseph E. Gatt, Bradley R. Fingland, William E. Lewis, Patrick L. Hanks

Patent number: 9290701Abstract: Processes are provided for producing a diesel fuel product having a sulfur content of 15 wppm or less (e.g., 10 wppm or less) from feed sources that include a biocomponent feedstock. The biocomponent feedstock can be initially co-processed with a mineral feed in a fluidized bed stage, such as an ebullating bed processing stage. Ebullating bed processing can mitigate the impact of the biocomponent feed on other hydrotreatment aspects of a diesel boiling range feed. Challenged biocomponent feeds can be handled by introducing the biocomponent feed into the ebullating bed reactor in a manner that reduces the fouling impact of the feed.Type: GrantFiled: March 31, 2014Date of Patent: March 22, 2016Assignee: ExxonMobil Research and Engineering CompanyInventors: Patrick L. Hanks, William Ernest Lewis, Edward Stanley Ellis, Kathryn Younger Cole

Patent number: 8853474Abstract: A biocomponent feedstock can be hydroprocessed using a hydrogen-containing refinery as a source of hydrogen gas. A relatively low cost catalyst, such as a water gas shift catalyst and/or spent hydrotreating catalyst, can be used as a hydrogenation catalyst for the process. The hydroprocessing can allow for olefin saturation and/or deoxygenation of the biocomponent feed by using a relatively low value refinery stream, e.g., containing from about 20 mol % to about 60 mol % hydrogen.Type: GrantFiled: July 15, 2010Date of Patent: October 7, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Patrick L. Hanks, Edward S. Ellis

Patent number: 8828217Abstract: Diesel fuel is produced from a feedstock that is at least partially biocomponent in origin. A feedstock is treated in a reactor including one or more hydrotreating zones having a continuous gas phase. The liquid effluent from the hydrotreating zones is then hydroprocessed in a hydroprocessing zone having a continuous liquid phase, such as a hydroprocessing zone in the same reactor. The hydroprocessing zone can be operated under effective catalytic dewaxing conditions.Type: GrantFiled: June 24, 2011Date of Patent: September 9, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Patrick L. Hanks, William E. Lewis

Patent number: 8816141Abstract: Processes are provided for deoxygenation of a biocomponent feedstock with reduced hydrogen consumption. The biocomponent feedstock can be processed under relatively low hydrogen partial pressures and at a relatively low treat gas ratio compared to the hydrogen need of the feedstock. The relatively low pressure, relatively low treat gas ratio hydroprocessing can result in reduced production of water and carbon monoxide and in increased production of carbon dioxide compared to relatively higher pressure process conditions.Type: GrantFiled: August 23, 2010Date of Patent: August 26, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Kathryn Y. Cole, Patrick L. Hanks, William E. Lewis

Publication number: 20140178278Abstract: Systems and methods are provided for performing CO2 sorption and regeneration processes that can take advantage of phase changes between solutions of amine-CO2 reaction products and precipitate slurries, where the slurry particles can include solid precipitates formed based on the amine-CO2 reaction products. An amine solution can be used to capture CO2 from a gas phase stream. During this initial capture process, the amine-CO2 reaction product can remain in solution. The solution containing the amine-CO2 reaction product can then be exposed to a set of conditions which result in precipitation of a portion of the amine-CO2 reaction product to form a slurry. The precipitate slurry can be passed into one or more release stages where the conditions for the slurry are altered to allow for release of the CO2.Type: ApplicationFiled: November 22, 2013Publication date: June 26, 2014Applicant: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Michael Siskin, Patrick L. Hanks, Pavel Kortunov, Robert B. Fedich, Patrick P. McCall, Hans Thomann, Daniel Leta, Lisa S. Baugh, David C. Calabro, Harry W. Deckman

Patent number: 8686203Abstract: A process for preparing fuels, such as diesel fuels or jet fuels, by hydrotreating vegetable oils or fatty acid derivatives that may be applied to existing equipment for treating fossil fuels. The process comprises feeding hydrotreating a combined oxygenate feed stream, such as FAME, and a hydrocarbon feed stream until not more than 86 wt % of the esters in the oxygenate feed stream are converted to hydrocarbons, and optionally further hydrotreating the product stream within at least a second hydrotreatment reaction zone until at least 90 wt % of the esters in the oxygenate feed stream are converted to hydrocarbons, before removing and separating a hydrocarbon stream suitable for use as fuel.Type: GrantFiled: June 4, 2010Date of Patent: April 1, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Patrick L.
