Publication number: 20240110110Abstract: Processes and systems for quenching an effluent. In certain embodiments, the process can include contacting a pyrolysis effluent and a first quench medium to produce a first quenched effluent. A bottoms stream that can include tar and an overhead stream that can include ethylene and propylene can be obtained from the first quenched effluent. The first quench medium can include a first portion of the bottoms stream that can include a first portion of the tar. In certain embodiments, the process can also include hydroprocessing a second portion of the bottoms stream that can include a second portion of the tar to produce a hydroprocessed product. A hydroprocessed bottoms stream can be obtained from the hydroprocessed product. In certain embodiments, the process can also include contacting at least a portion of the hydroprocessed bottoms stream and the first portion of the bottoms stream to produce the first quench medium.Type: ApplicationFiled: September 16, 2020Publication date: April 4, 2024Inventors: Reyyan Koc-Karabocek, James R. Lattner, William A. Aslaner, David Spicer, Mark A. Rooney

Patent number: 10894925Abstract: A multi-stage process for upgrading tars is provided. A predominantly hydrotreating stage can be applied before a cracking stage, which can be a hydrocracking or a thermal cracking stage. Alternatively, a predominantly cracking stage, which can be a hydrocracking or a thermal cracking stage, can be applied before a hydrotreating stage. Apparatus suitable for performing the method is also provided.Type: GrantFiled: July 2, 2018Date of Patent: January 19, 2021Assignee: ExxonMobil Chemical Patents Inc.Inventors: Kapil Kandel, Bryan A.

Patent number: 10597592Abstract: A process is described for upgrading pyrolysis tar, such as steam cracker tar, by hydroprocessing in the presence of a utility fluid. The hydroprocessing conditions comprise a pressure >8 MPa and a weight hourly space velocity of combined pyrolysis tar and utility fluid >0.3 hr?1 and are selected so that the hydrogen consumption rate is in the range of 270 to 445 standard cubic meters/cubic meter (S m3/m3) of pyrolysis tar.Type: GrantFiled: August 2, 2017Date of Patent: March 24, 2020Assignee: ExxonMobil Chemical Patents Inc.Inventors: Kapil Kandel, Reyyan Koc-Karabocek, Teng Xu, Frank Cheng-Yu Wang, David Thomas Ferrughelli

Patent number: 10518234Abstract: Aspects of the invention provide a process for upgrading a hydrocarbon feed. The process includes providing a hydrocarbon feed and a utility fluid. Then selectively extracting from the feed at least a portion of particulates to produce a raffinate and an extract. Third hydroprocessing at least a portion of the raffinate.Type: GrantFiled: June 25, 2018Date of Patent: December 31, 2019Assignee: ExxonMobil Chemical Patents Inc.Inventors: James H. Beech, Jr., Reyyan Koc-Karabocek, Christopher M. Evans, Jeffrey C. Yeh, Teng Xu
