Publication number: 20230357003Abstract: Systems and methods are provided for using a reverse-flew reactor (or another reactor with flows in opposing directions at different parts of a process cycle) as part of a reaction system for production of ammonia and/or urea. Using a reverse flow reactor as part of an ammonia production process can provide a variety of advantages, including direct heating of the reaction environment, and simplified generation of multiple high-purity reagent streams for ammonia and/or urea synthesis.Type: ApplicationFiled: September 16, 2020Publication date: November 9, 2023Inventors: Anastasios I SKOULIDAS, Everett J. O'Neal, Ian J. Laurenzi

Patent number: 11485922Abstract: Kerosene boiling range or jet fuel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. The resulting kerosene boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight ratio, a low but substantial aromatics content, and a low sulfur content. Such fractions can potentially be used as fuel after a reduced or minimized amount of additional refinery processing. By reducing, minimizing, or avoiding the amount of refinery processing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.Type: GrantFiled: May 20, 2021Date of Patent: November 1, 2022Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Daniel E. Kadlecek, Randolph J. Smiley, Gregory K. Lilik, Mike T. Noorman, Shifang Luo, Ian J. Laurenzi, Poturovic Jasmina

Patent number: 11441089Abstract: Distillate boiling range and/or diesel boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. This unexpected combination of properties is characteristic of crude oils that can be fractionated to form distillate/diesel boiling range compositions that can be used as fuels/fuel blending products with reduced or minimized processing. The resulting distillate boiling range fractions and/or diesel boiling range fractions can have an unexpected combination of a high naphthenes to aromatics weight and/or volume ratio, a low but substantial aromatics content, and a low sulfur content.Type: GrantFiled: May 20, 2021Date of Patent: September 13, 2022Assignee: ExxonMobil Technology and Engineering CompanyInventors: Sheryl B. Rubin-Pitel, Timothy J. Anderson, Kenneth C. H. Kar, Marcia E. Dierolf, Shifang Luo, Ian J. Laurenzi, Xinrui Yu, Yi Xu

Patent number: 11390820Abstract: Naphtha boiling range compositions are provided that are formed from crude oils with unexpected combinations of high naphthenes to aromatics weight and/or volume ratio and a low sulfur content. The resulting naphtha boiling range fractions can have a high naphthenes to aromatics weight ratio, a low but substantial content of aromatics, and a low sulfur content. In some aspects, the fractions can be used as fuels and/or fuel blending products after fractionation with minimal further refinery processing. In other aspects, the amount of additional refinery processing, such as hydrotreatment, catalytic reforming and/or isomerization, can be reduced or minimized. By reducing, minimizing, or avoiding the amount of hydroprocessing needed to meet fuel and/or fuel blending product specifications, the fractions derived from the high naphthenes to aromatics ratio and low sulfur crudes can provide fuels and/or fuel blending products having a reduced or minimized carbon intensity.Type: GrantFiled: May 20, 2021Date of Patent: July 19, 2022Assignee: ExxonMobil Technology and Engineering CompanyInventors: Matthew H. Lindner, Scott K. Berkhous, Mike T. Noorman, Gregory K. Lilik, Shifang Luo, Ian J. Laurenzi, Jasmina Poturovic

Patent number: 10099972Abstract: Systems and a method are provided for producing an aromatic hydrocarbon and generating electricity from a tail gas stream. The method includes feeding a first stream including a raw natural gas into a reactor. The method includes converting the first stream, at least in part, to a second stream including an aromatic hydrocarbon within the reactor. The method includes separating the second stream into a tail gas stream and a liquid aromatic hydrocarbon stream and combusting at least a portion of the tail gas stream to generate electricity.Type: GrantFiled: November 3, 2014Date of Patent: October 16, 2018Assignee: ExxonMobil Upstream Research CompanyInventors: Paul F. Keusenkothen, Timothy A. Barckholtz, J. Tim Cullinane, Robert D. Denton, Frank Hershkowitz, Ian J. Laurenzi
