Patent number: 11415568Abstract: Systems and methods for implicit chemical resolution of vacuum gas oils and fit quality determination are disclosed. The systems and methods include utilizing an FT-IR spectrum of an unknown VGO composition, and a database of FT-IR spectra of known VGO compositions, to determine a model of composition for the unknown VGO composition. Additionally, the fit quality for the model of composition is determined by performing a partial least squares analysis on specific spectral regions of interest in the FT-IR spectrum of the unknown VGO composition.Type: GrantFiled: September 10, 2019Date of Patent: August 16, 2022Assignee: ExxonMobil Technology and Engineering CompanyInventors: Bryan T.

Patent number: 11402323Abstract: Systems and methods for determining performance properties of an unknown composition are disclosed. The performance properties can include a Research Octane Number (RON), a Motor Octane Number (MON), and/or a cetane number. The systems and methods include utilizing an optical spectrum of an unknown composition to determine a model of composition, where the model of composition includes a molecular identity and a relative abundance for components therein. The model of composition is then utilized to calculate one or more performance properties. Additionally, the fit quality for the model of composition is determined by performing a partial least squares analysis on specific spectral regions of interest in the optical spectra of the unknown composition.Type: GrantFiled: September 10, 2019Date of Patent: August 2, 2022Assignee: ExxonMobil Technology and Engineering CompanyInventors: Bryan T.

Patent number: 8887557Abstract: Two quantitative separation approaches to fractionate de-asphalted oils (DAOs) into seven classes of compounds (saturates, 1-4+ ring-aromatics, sulfides, and polars). In the first step (named as “SGS”) of present invention, the DAO of a petroleum vacuum resid is separated in to four classes of compounds, namely saturates, aromatics, and sulfides. In this first step of separation, about 3 grams of a DAO can be separated. Whereas in the second step (named as “ARC” separation) of invention, only less than 300 mg of the aromatic fraction obtained in “SGS” (described above) can be further fractionated at very low temperature (about ?40 degrees centigrade) into 4 fractions, namely 1-ring, 2-ring, 3-ring, and 4+-ring aromatics. The present invention protocol is suitable for a wide range of compositionally different DAOs of petroleum vacuum resids.Type: GrantFiled: September 1, 2011Date of Patent: November 18, 2014Assignee: ExxonMobil Research and Engineering CompanyInventors: Birbal Chawla, Bryan E.
