Patent number: 10550341Abstract: Methods are provided for producing lubricant base stocks from deasphalted oils formed by sequential deasphalting. The deasphalted oil can be exposed a first deasphalting process using a first solvent that can provide a lower severity of deasphalting and a second deasphalting process using a second solvent that can provide a higher severity of deasphalting. This can result in formation of at least a deasphalted oil and a resin fraction. The resin fraction can represent a fraction that traditionally would have been included as part of a deasphalter rock fraction.Type: GrantFiled: December 27, 2016Date of Patent: February 4, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Mohsen N. Harandi, Doron Levin, Himanshu Gupta, James R. Lattner, Glenn C. Wood, Keith K. Aldous, Timothy L. Hilbert, Michael B. Carroll, Ajit B. Dandekar, Sara L. Yohe, Stephen H. Brown, Tracie L.

Patent number: 10464009Abstract: The embodiments of the disclosure relate generally to adsorbent beds, adsorbent contactors, and methods of using same. The disclosure includes polymer filaments that include an adsorbent particle, such as a zeolite, metal oxide, metal organic framework. A plurality of fibers composed of the polymer filaments can be formed into an adsorbent bed for use in pressure swing and/or temperature swing adsorption processes. The plurality of fibers can be packed into a bed randomly, spirally wound, or woven into a fabric that can be formed into a contacting structure. The adsorbent particle can be contained within the polymer filament and can interact with a medium having a component for adsorption by being in fluid communication with the medium via tortuous pathways within the polymer.Type: GrantFiled: June 16, 2017Date of Patent: November 5, 2019Assignee: ExxonMobil Upstream Research CompanyInventors: Tracie L.

Patent number: 10451602Abstract: A method of screening a hydrocarbon stream for potential toxicological hazards. The method involves providing a hydrocarbon stream; conducting 2-dimensional gas chromatography (2D-GC) analysis to quantify saturates and aromatic distribution in the hydrocarbon stream; identifying 2-8 ring aromatic distribution and weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis; relating the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis to a mutagenicity index (MI), in which the MI is determined in accordance with ASTM Standard Method E 1687; and assessing a potential toxicological hazard of the hydrocarbon stream based on the weight percentage of 2-8 ring aromatic molecules in the hydrocarbon stream from the 2D-GC analysis and a MI threshold value. The 2-8 ring aromatic distribution preferably includes 3-6 ring aromatics, more preferably 3.5-5.5 ring aromatics.Type: GrantFiled: March 28, 2017Date of Patent: October 22, 2019Assignee: ExxonMobil Research And Engineering CompanyInventors: Tracie L.

Patent number: 10435359Abstract: Provided herein are various methods for forming alkylaromatic sulfonate compositions and blended alkylaromatic sulfonate compositions, and such compositions themselves. The methods of various embodiments include obtaining a C8-C30 hydrocarbon mixture, optionally treating the mixture to concentrate the mixture in sulfonatable aromatics, and sulfonating the mixture to form the alkylaromatic sulfonates. The mixture or treated mixture may be blended with linear alkyl benzene (LAB) compositions and sulfonated, and/or the alkylaryl sulfonates may be blended with linear alkylbenzene sulfonate (LAS) compositions, to form the blended alkylaromatic sulfonates of some embodiments. These compositions and processes for making them may be tailored to serve a variety of end uses, such as detergents in cleaning solutions or for enhanced oil recovery operations, and/or as low foaming and/or hydrotropic additives in detergent formulations, and the like.Type: GrantFiled: August 9, 2017Date of Patent: October 8, 2019Assignee: ExxonMobil Chemical Patents Inc.Inventors: Tracie L.
