Abstract (en)
[origin: WO2014001552A1] The present invention provides a process to prepare a first middle distillates fraction, a second middle distillates fraction, a distillate base oil and a residual base oil, which process at least comprises the following steps: (a) providing a Fischer-Tropsch product stream; (b) separating the Fischer-Tropsch product stream of step (a), thereby obtaining at least a low boiling fraction, boiling below a temperature in the range of from 300 to 450°C, and a high boiling fraction, boiling above a temperature in the range of from 300 to 450°C; (c) subjecting the high boiling fraction of step (b) to a hydrocracking/hydroisomerization step to obtain an at least partially isomerised product stream; (d) separating the product stream of step (c), thereby obtaining a first middle distillates fraction, a heavy distillates fraction and a residual fraction, wherein the residual fraction has a T5 wt. % boiling point of between 400 and 650°C; (e) dewaxing the low boiling fraction of step (b) to obtain a second middle distillates fraction; f) dewaxing the heavy distillates fraction of step (d) to obtain a distillate base oil; and g) dewaxing the residual fraction of step (d) to obtain a residual base oil.
