Abstract:
    Process for the preparation of bitumen in which a residual fraction of a thermally cracked hydrocarbon feedstock is distilled under subatmospheric pressure at a maximum distillation temperature that corresponds with the boiling point at the subatmospheric pressure of hydrocarbons having an atmospheric boiling point of 455-540 DEG C and at least a part of the distillation residue is recovered as bitumen.
