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.
制备碳氢化合物馏分和碳氢化合物残渣的工艺,包括将催化裂化或加氢裂化碳氢化合物原料所得产品的残余部分与第二种碳氢化合物馏分混合,第二种碳氢化合物馏分的沸程至少为 50%w,沸点温度高于 400°C,然后将所得混合物进行亚大气压蒸馏,得到至少一种馏分和一种残渣。 所制备的残渣是沥青组合物中的一种合适成分。
