Patent number: 9327260Abstract: This invention relates to a process and system for cracking hydrocarbon feedstock containing vacuum resid comprising: (a) subjecting a vacuum resid to a first thermal conversion in a thermal conversion reactor (such as delayed coker, fluid coker, Flexicoker™, visbreaker and catalytic hydrovisbreaker) where at least 30 wt % of the vacuum resid is converted to material boiling below 1050° F. (566° C.); (b) introducing said thermally converted resid to a vapor/liquid separator, said separator being integrated into a steam cracking furnace, to form a vapor phase and liquid phase; (c) passing said vapor phase to the radiant furnace in said steam cracking furnace; and (d) recovering at least 30 wt % olefins from the material exiting the radiant furnace (based upon the weight of the total hydrocarbon material exiting the radiant furnace).Type: GrantFiled: February 15, 2013Date of Patent: May 3, 2016Assignee: ExxonMobil Chemical Patents Inc.Inventors: S. Mark Davis, Richard C. Stell, Jiunn-Shyan Liou, Stephen H. Brown, Paul F. Keusenkothen, Arthur R. Di Nicolantonio, John J. Waldrop

Patent number: 9181147Abstract: In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of C4+ olefinic and aromatic hydrocarbons is recovered from the first stream and is fed together with a methylating agent to a reaction zone containing a catalyst under reaction conditions including a temperature of about 450° C. to about 700° C., such that aromatics components in the second stream undergo dealkylation, transalkylation and/or methylation and aliphatic components undergo cracking and aromatization to produce a third stream having an increased xylene content compared with said second stream and a C3? olefin by-product. The C3? olefin by-product is recovered and para-xylene is removed from at least part of said third stream.Type: GrantFiled: May 7, 2012Date of Patent: November 10, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: Larry L. Iaccino, S. Mark Davis, John D. Y. Ou, Xiaobo Zheng

Patent number: 9067851Abstract: A selective hydrogenation method is particularly effective in selectively hydrogenating alkynyl compounds, such as acetylene or methyl acetylene, over alkenyl compounds, such as ethylene. The method produces a relatively high quantity of heat during the selective hydrogenation reaction. This production of heat is, however, quite beneficial in that enough heat is produced such that a substantial portion of the produced heat can be recovered for heat efficiency purposes.Type: GrantFiled: August 9, 2012Date of Patent: June 30, 2015Assignee: ExxonMobil Chemical Patents Inc.Inventors: S. Mark Davis, Neeraj Sangar, Paul F. Keusenkothen

Publication number: 20140323783Abstract: A method and system for converting hydrocarbons into C2+ unsaturates is described. The method includes providing a structural member upstream of a reaction zone having a surface of a catalytic material, wherein the catalytic material is rendered catalytically active to promote the reaction of coke and/or coke precursors with hydrogen (H2) and/or an oxidant. Then, the method involves exposing a hydrocarbon stream to the catalytic material, wherein the hydrocarbon stream comprising coke and/or coke precursors react in the presence of the catalytic material to convert at least a portion of the coke and/or coke precursors to vapor products. Finally, the hydrocarbons in the hydrocarbon stream containing vapor products and hydrocarbons are converted in the reaction zone to produce a reactor product having C2+ unsaturates.Type: ApplicationFiled: April 9, 2012Publication date: October 30, 2014Inventors: Paul F. Keusenkothen, Larry Lee Iaccino, Ronald G. Searle, S. Mark Davis
