Abstract: Partial upgrading processes can include thermal treatment combined with solvent deasphalting, and recycling of certain streams, to process bitumen feedstocks and produce a bitumen product. The thermal treatment can be done so that the feedstock is in liquid phase at conditions below incipient coking conditions. Solvent deasphalting can be done before or after thermal treatment depending on the configuration of the process. Subjecting the bitumen feedstock to a partial upgrading can facilitate viscosity reduction of the bitumen feedstock and can facilitate avoiding the need for the addition of an external source of hydrogen.
