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.

A process for preparing light distillate fractions and medicinal oil from heavy hydrocarbon oils comprises two-stage hydrocracking, fractionation distillation and catalytic hydrotreatment of at least part of the fractionation residue.

Process for preparing hydrocarbons

The daylight stability of hydroprocessed oils is improved by adding thereto (1) singlet oxygen quenchers suitably selected from the class consisting of carotenes, aliphatic amines and heterocyclic amines, and (2) certain aromatic secondary amines as antioxidants.
