Abstract: Embodiments of the present disclosure generally relate to diluent oils for viscosity modifiers and additive packages. Embodiments of the present disclosure also generally relate to lubricating oil compositions that include viscosity modifier concentrates and lubricating oil compositions that include additive package concentrates. Improved diluent oils capable of conveniently and cost effectively improving overall lubricant performance are provided.

Abstract: Methods are provided for processing deasphalted gas oils derived from thermally cracked resid fractions to form Group I, Group II, and/or Group III lubricant base oils. The yield of lubricant base oils (optionally also referred to as base stocks) can be increased by thermally cracking a resid fraction at an intermediate level of single pass severity relative to conventional methods. By performing thermal cracking to a partial level of conversion, compounds within a resid fraction that are beneficial for increasing both the viscosity and the viscosity index of a lubricant base oil can be retained, thus allowing for an improved yield of higher viscosity lubricant base oils from a thermally cracked resid fraction.

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.

Abstract: 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.

Abstract: Methods are provided for upgrading disadvantaged feeds for use in lubricant base stock production. A disadvantaged feed can be upgraded by hydroprocessing the feed to form a hydroprocessed bottoms fraction. The hydroprocessed bottoms fraction can then be used as a feed for forming Group I and/or Group II lubricant base stocks, optionally in combination with a conventional feed for lubricant production. The remaining portions of the hydroprocessing effluent can optionally be used for FCC processing and/or for other conventional applications of naphtha and distillate fractions.

Abstract: Methods are provided for rapidly characterizing a feedstock being considered for lubricant base oil production in order to determine the viscosity index potential of the feedstock. It has unexpectedly been discovered that the DDVI value for a feedstock at a specified pour point can be predicted based on a) the feed distillate residual wax content at a temperature as determined by Differential Scanning Calorimetry, such as the feed distillate residual wax content at a temperature corresponding to the specified pour point temperature; b) the feed distillate refractive index; c) the feed distillate kinematic viscosity at a temperature, such as kinematic viscosity at 100° C.; and d) the distillate volume-averaged boiling point. Based on this unexpected correlation, the VI potential of a feedstock can be determined based on measurement of properties that can be performed on a time scale corresponding to one or a few days using a few milliliters of feedstock.

Abstract: Systems and methods are provided for characterizing kerosene fractions in order to determine whether the fractions will satisfy a desired thermal breakpoint specification. Additionally, hydrotreating conditions can be determined that will result in a hydrotreated kerosene fraction that satisfies the desired thermal breakpoint specification. The hydrotreating conditions can be determined based on a model constructed from data corresponding to a plurality of reference samples. The model can include data for compositional groups within the reference samples. The data for compositional groups can be derived from Fourier transform ion cyclotron resonance mass spectrometry data or from another suitable characterization technique.
