Abstract
Fuels and/or fuel blending components can be formed from hydroprocessing of high lift deasphalted oil. The high lift deasphalting can correspond to solvent deasphalting to produce a yield of deasphalted oil of at least 50 wt %, or at least 65 wt %, or at least 75 wt %. The resulting fuels and/or fuel blending components formed by hydroprocessing of the deasphalted oil can have unexpectedly high naphthene content and/or density. Additionally or alternately, the resulting fuels and/or fuel blending components can have a clear and bright appearance.
