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.

Abstract: Processes comprising: heat treating a heavy hydrocarbon feedstock in a heat treatment unit to produce a first effluent comprising a heat treated product; at least partially removing a mixture of gas and distillate from the first effluent in a first separation unit to produce a second effluent comprising a separation bottom product; deasphalting the second effluent in a second separation unit in the presence of a first solvent to produce: a soluble product fraction comprising a first portion of the first solvent, a deasphalted oil (DAO) product, and a first pitch product; an insoluble product fraction comprising a second portion of the first solvent and a portion of the first pitch product; and at least partially removing the second portion of the first solvent from the first pitch product in a third separation unit to produce a purified pitch product.
