(371° C.) or less and having an aromatic content of 50 wt % or greater to form a product comprising 50 wt % or greater of the hydrocarbons having a boiling point of 700° F. (371° C.) or less and having an aromatic content of 20 wt % or less.

Abstract: A method for producing pitch can include: hydroprocessing a challenged feed from a refinery operation to produce a hydroprocessed product; distilling the hydroprocessed product to yield one or more upgraded fractions and a resid fraction; and solvent deasphalting the resid fraction to yield a deasphalted oil stream and a hydroprocessed pitch stream. The resultant pitch can have a micro carbon residue (MCR) of 50 wt % or greater, a solubility in toluene of 95 wt % or greater, and a softening point of 200° C. or less. The pitch can optionally be fluxed with a fluxing solvent.

Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

Abstract: 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.

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.

Abstract: The disclosure relates to processes for upgrading heavy hydrocarbon oils such as heavy crude oils, atmospheric residuum, vacuum residuum, heavy oils from catalytic treatment, heavy cycle oils from fluid catalytic cracking, thermal tars, as oils from visbreaking, oils from oil sands, bitumen, deasphlter rock, and heavy oils derived from coal. The process utilizes a utility fluid including recycled liquid hydroprocessed product containing a significant amount of single or multi-ring aromatics. Unlike conventional fixed bed resid hydroprocessing, the process can be operated at temperatures pressures and reactor conditions that favor the desired hydrocracking reactions over aromatics hydrogenation reduce the coking tendencies of heavy hydrocarbon oils.
