摘要:
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°C and at least a part of the distillation residue is recovered as bitumen.
摘要:
Process 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°C, and subjecting the resulting mixture to a subatmospheric distillation yielding at least one distillate fraction and one residue. The residue this prepared is a suitable component in bitumen compositions.
