Patent number: 11530361Abstract: This invention relates to a process for determining the suitability of pyrolysis tar, such as steam cracker tar, for upgrading using hydroprocessing without excessive fouling of the hydroprocessing reactor. A pyrolysis tar is sampled, the sample is analyzed to determine one or more characteristics of the tar related to tar reactivity, and the analysis is used to determine conditions under which the tar can be blended, pre-treated, and/or hydroprocessed.Type: GrantFiled: October 7, 2021Date of Patent: December 20, 2022Assignee: ExxonMobil Chemical Patents Inc.Inventors: Kapil Kandel, Glenn A. Heeter, Teng Xu, Giovanni S. Contello, Krystle J. Emanuele

Patent number: 11401473Abstract: Processes for improving hydrocarbon feedstock compatibility are provided. More specifically, a process for preparing a liquid hydrocarbon product includes heat soaking a tar stream to produce a reduced reactivity tar and blending the reduced reactivity tar with a utility fluid comprising recycle solvent to produce a lower viscosity, reduced reactivity tar. The process also includes hydroprocessing the lower viscosity, reduced reactivity tar at a temperature of greater than 350° C. to produce a total liquids product containing the liquid hydrocarbon product and the recycle solvent. The process further includes separating the recycle solvent from the total liquids product, where the recycle solvent has the SBN of greater than 110, and flowing the recycle solvent to the reduced reactivity tar for blending to produce the lower viscosity, reduced reactivity tar.Type: GrantFiled: August 20, 2019Date of Patent: August 2, 2022Assignee: ExxonMobil Chemical Patents Inc.Inventors: Kapil Kandel, Teng Xu, Glenn A. Heeter, Frank Cheng-Yu Wang, Anthony S. Mennito, David T. Ferrughelli, Krystle J. Emanuele

Patent number: 11236276Abstract: The present disclosure provides methods for hydroprocessing of heavy oils, such as pyrolysis tars. For example, a process for preparing a liquid hydrocarbon product includes providing a first process stream comprising a reduced reactivity tar, and blending the first process stream with a utility fluid to produce a second process stream comprising solids and a reduced reactivity, lower viscosity tar. The method can includes introducing the second process stream into a guard reactor without sulfiding the guard reactor catalyst(s) prior to introducing the second process stream into the guard reactor. The method includes hydroprocessing the second process stream in the guard reactor under mild hydroprocessing conditions to produce a third process stream. The method includes hydroprocessing the third process stream to produce a fourth process stream having a bromine number (BN) lower than 12 and comprising the liquid hydrocarbon product and the utility fluid.Type: GrantFiled: August 19, 2019Date of Patent: February 1, 2022Assignee: ExxonMobil Chemical Patents Inc.Inventors: Krystle J.
