Abstract: Disclosed are Group III base stocks comprising greater than or equal to about 90 wt. % saturated hydrocarbons (saturates); a viscosity index from 120 to 145; a unique ratio of molecules with multi-ring naphthenes to single ring naphthenes (2R+N/1RN); a unique ratio of branched carbons to straight chain carbons (BC/SC); a unique ratio of branched carbons to terminal carbons (BC/TC); and unique MRV behavior as a function of base stock naphthene ratio (2R+N/1RN). A method for preparing the base stocks is also disclosed. Also disclosed is a lubricating oil having the base stock as a major component, and an additive as a minor component.

Abstract: Systems and methods are provided for co-processing of used lubricant oils with a coker feedstock in a fluidized coking process to form lubricant base stocks. The fluidized coking process can remove contaminants and/or additives from used lubricant oils with modest conversion of the lubricant boiling range portion.

Abstract: Methods and catalysts are provided for performing dewaxing of diesel boiling range fractions, such as trim dewaxing, that allow for production of diesel boiling range fuels with improved cold flow properties at desirable yields. In some aspects, the methods can include use of dewaxing catalysts based on an MEL framework structure (ZSM-11) to provide improved dewaxing activity. This can provide sufficient dewaxing activity to achieve a desired level of improvement in cold flow properties at the lower hydrotreating temperatures that are generally desired near the start of operation of a hydrotreating reactor. In other aspects, the methods can include use of MEL dewaxing catalysts with reduced ratios of molecular sieve to binder so that trim dewaxing can be provided while maintaining a desirable yield under end-of-run hydrotreating conditions.

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.
