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: Systems and methods are provided for reducing the end point of distillate fuel boiling range fractions while reducing or minimizing conversion of the distillate fuel to naphtha or light ends. To perform end point reduction, a distillate boiling range fraction is exposed to a conversion catalyst that has a total surface area of at least 200 m2/g, an average pore size of 12 Angstroms or more, and/or a low acidity, where the conversion catalyst includes a supported Group 8-10 metal, such as a supported Group 8-10 noble metal. Such a conversion catalyst can have improved activity for reducing end point of a distillate fuel fraction while reducing or minimizing conversion relative to 177° C. Performing end point reduction using such a catalyst can allow for increased yields of distillate fuel boiling range products by allowing increased amounts of heavy feed components to be included in the input to a distillate fuel processing train.

Abstract: Systems and methods are provided for integration of use deasphalted resid as a feed for fuels and/or lubricant base stock production with use of the corresponding deasphalter rock for gasification to generate hydrogen and/or fuel for the fuels and/or lubricant production process. The integration can include using hydrogen generated during gasification as a fuel to provide heat for solvent processing and/or using the hydrogen for hydroprocessing of deasphalted oil.

Abstract: Methods are provided for forming lubricant base stocks from feeds such as vacuum resid or other 510° C.+ feeds. A feed can be deasphalted and then catalytically and/or solvent processed to form lubricant base stocks, including bright stocks. The catalytic processing can correspond to processing in at least two stages. The amount of conversion performed in each stage can be varied to produce bright stocks with various properties.
