PROCESS TO PREPARE MIDDLE DISTILLATES AND BASE OILS |
摘要 |
<p>The present invention provides a process to prepare a first middle distillates fraction, a second middle distillates fraction and one or more base oils, 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 and a residual fraction, wherein the residual fraction has a T10wt.% boiling point of between 200 and 450°C; (e) dewaxing the low boiling fraction of step (b) to obtain a second middle distillates fraction; and f) dewaxing the residual fraction of step (d) to obtain one or more base oils.</p> |
