ABSTRACT:
A process for producing additional liquid products from a heavy hydrocarbon material by vis-breaking of a separated asphaltene-containing fraction under controlled conditions of temperature and pressure. The asphaltene-containing fraction is obtained by contacting the heavy hydrocarbon material with a first solvent under elevated temperature and pressure conditions to separate the asphaltenes as a heavy phase from the remainder of the heavy hydrocarbon material. The products of the vis-breaking operation comprise distillable and substantially nondistillable liquid products in association with a residue including organometallic compounds. The distillable and substantially nondistillable liquid products then are separated from the residue. The distillable products can be separated by distillation. The nondistillable products are separated from the residue employing a second solvent maintained under elevated temperature and pressure conditions and then recovered as a liquid phase product.
