Patent number: 11377402Abstract: Systems and methods are provided for integration of an aromatic formation process for converting non-aromatic hydrocarbon to an aromatic product and subsequent methylating of a portion of the aromatic product to produce a methylated product, with improvements in the aromatic formation process and/or the methylation process based on integrating portions of the secondary processing trains associated with the aromatic formation process and the methylation process. The aromatic formation process and methylation process can be used, for example, for integrated production of specialty aromatics or gasoline blending components.Type: GrantFiled: April 19, 2018Date of Patent: July 5, 2022Assignee: ExxonMobil Chemical Patents Inc.Inventors: Catherine M.

Publication number: 20220195309Abstract: Systems and methods are provided for integration of a reactor for polyolefin pyrolysis with the effluent processing train for a steam cracker. The polyolefins can correspond to, for example, polyolefins in plastic waste. Integrating a process for polyolefin pyrolysis with a steam cracker processing train can allow a mixture of polymers to be converted to monomer units while reducing or minimizing costs and/or equipment footprint. This can allow for direct conversion of polyolefins to the light olefin monomers in high yield while significantly lowering capital and energy usage due to integration with a steam cracking process train. The integration can be enabled in part by selecting feeds with appropriate mixtures of various polymer types and/or by limiting the volume of the plastic waste pyrolysis product relative to the volume from the steam cracker(s) in the steam cracking process train.Type: ApplicationFiled: June 12, 2020Publication date: June 23, 2022Inventors: Sundararajan Uppili, Bryan A. Patel, Randolph J. Smiley, Lawrence R. Gros, Anthony Go, Saurabh S. Maduskar, Melissa D. Foster, Philippe Laurent

Patent number: 11053176Abstract: Disclosed is a process for producing mixed xylenes and C9+ hydrocarbons in which an aromatic hydrocarbon feedstock comprising benzene and/or toluene is contacted with an alkylating agent comprising methanol and/or dimethyl ether under alkylation conditions in the presence of an alkylation catalyst to produce an alkylated aromatic product stream comprising the mixed xylenes and C9+ hydrocarbons. The mixed xylenes are subsequently converted to para-xylene, and the C9+ hydrocarbons and its components may be supplied as motor fuels blending components. The alkylation catalyst comprises a molecular sieve having a Constraint Index in the range from greater than zero up to about 3. The molar ratio of aromatic hydrocarbon to alkylating agent is in the range of greater than 1:1 to less than 4:1.Type: GrantFiled: March 15, 2019Date of Patent: July 6, 2021Assignee: ExxonMobil Chemical Patents Inc.Inventors: Tan-Jen Chen, Wenyih F.

Patent number: 10906851Abstract: Para-xylene is separated from a mixture of xylenes and ethylbenzene by a separation process. An ortho-selective adsorbent is used to reduce the ortho-xylene concentration of the xylenes, prior to contact of the xylenes and ethylbenzene with a para-selective adsorbent. The stream rich in ortho-xylene may be isomerized in the liquid phase to increase the amount of para-xylene therein. The para-xylene-depleted stream may be treated in the vapor phase to remove the ethylbenzene and then subjected to isomerization in the liquid phase to produce a stream having a higher than equilibrium amount of para-xylene.Type: GrantFiled: February 9, 2017Date of Patent: February 2, 2021Assignees: EXXONMOBIL CHEMICAL PATENTS INC., GEORGIA TECH RESEARCH CORPORATTONInventors: Meha Rungta, Robert G.

Patent number: 10358401Abstract: Para-xylene is separated from a mixture of C8 aromatics using a simulated moving bed (SMB) adsorption process, wherein a MOF is used as an adsorbent and an alkane or alkene having 7 or less carbon atoms, such as hexane or heptane is used as desorbent. Because of the difference in boiling points of a hexane or heptane desorbent as compared to conventional desorbents such as toluene or para-diethylbenzene, less energy is required to separate hexane or heptane from C8 aromatics by distillation than the energy required to separate toluene or diethylbenzene from C8 aromatics by distillation.Type: GrantFiled: July 29, 2016Date of Patent: July 23, 2019Assignees: EXXONMOBIL CHEMICAL PATENTS INC., GEORGIA TECH RESEARCH CORPORATIONInventors: Meha Rungta, Jeevan S.

Publication number: 20130144097Abstract: In a process for producing para-xylene, a naphtha feed is reformed under conditions effective to convert at least 50 wt % of the naphthenes in the naphtha feed to aromatics, but to convert no more than 25 wt % of the paraffins in the naphtha feed, and thereby produce a reforming effluent. A first stream containing benzene and/or toluene is removed from the reforming effluent and is fed to a xylene production unit under conditions effective to convert benzene and/or toluene to xylenes. In addition, a second stream containing C8 aromatics is removed from the reforming effluent and is fed, together with at least part of the xylenes produced in the xylene production unit, to a para-xylene recovery unit to recover a para-xylene product stream and leave a para-xylene-depleted C8 stream.Type: ApplicationFiled: November 14, 2012Publication date: June 6, 2013Applicant: ExxonMobil Chemical Patents Inc.Inventors: Timothy P.
