Abstract
A process for converting a heavy charge such as a heavy crude oil, a tar from oil sand and a distillation residue, by combining a hydroconversion with catalysts in slurry phase process, a distillation or flash process, and a deasphalting process, wherein the three processes operate on mixed streams consisting of fresh charge and recycled streams.
