  • Process for the preparation of a hydrocarbonaceous distillate and a residue
    Patent number: 4755277
    Abstract: A process is disclosed for the preparation of a hydrocarbonaceous distillate and a hydrocarbonaceous residue, which comprises mixing a residual fraction of a product obtained by catalytic cracking or hydrocracking a hydrocarbonaceous feedstock, with a second hydrocarbonaceous fraction having such a boiling range that at least 50% w boils at a temperature above 400.degree. C., and subjecting the resulting mixture to a subatmospheric distillation yielding at least one distillate fraction and one residue. The residue thus prepared is a suitable component in bitumen compositions.
