Abstract
The present disclosure provides a process that includes providing bitumen; performing thermal upgrading on the bitumen to form mildly upgraded bitumen; distilling the mildly upgraded bitumen to form streams of naphtha; distillates and/or gas oils; and residue; combining the naphtha and residue to form a naphtha/residue stream, which causes deasphalting to occur, and forming streams of deasphalted oil and high-carbon pitch comprising asphaltenes; and adding the distillates and/or gas oils to the deasphalted oil to form partially upgraded bitumen.

A process comprising:
- a. providing dilbit;
- b. performing thermal upgrading on the dilbit to form mildly upgraded dilbit;
- c. distilling the mildly upgraded dilbit to form a light stream and streams of distillates and/or gas oils;
- and residue;
- d. separating the light stream into diluent and a second light stream;
- e. hydropolishing the second light stream to form naphtha;
- d. combining the naphtha and residue to form a naphtha/residue stream, which causes deasphalting to occur, and forming streams of deasphalted oil and high-carbon pitch comprising asphaltenes;
- and
- e. adding the distillates and/or gas oils to the deasphalted oil to form partially upgraded bitumen.
