Also, an apparatus for upgrading a hydrocarbon feed containing sulfur, metals, and asphaltenes, the apparatus comprising: a distillation column for receiving the feed and producing a substantially asphaltene-free, and metal-free distillate fraction and a non-distilled fraction containing sulfur, asphaltene and metals; and means for producing a hydrogen donor diluent from at least some of the substantially asphaltene-free, and metal-free distillate fraction. The apparatus also includes a solvent deasphalting unit for processing the non-distilled fraction and producing a deasphalted oil stream and an asphaltene stream and combining the hydrogen donor diluent with the deasphalted oil stream to form a combined stream; and a thermal cracker for thermally cracking the combined stream and forming a thermally cracked stream whereby the thermally cracked stream is applied to the distillation column.
