| 摘要 |
The invention relates to a method for the treatment of an olefin containing hydrocarbon feedstock (110), wherein said feedstock (110) successively undergoes the following steps: (i) selective catalytic hydrogenation, (ii) a fractionation into at least a light cut (113), (iii) a treatment of the light cut (113) on an adsorbent to obtain at least one nitrogen and sulfur depleted light cut (115), (iv) oligomerization of said nitrogen and sulfur depleted light cut (115) to obtain a heavier cut effluent (120) essentially consisting of a middle distillate fraction (117), (v) a fractionation of the effluent (120) of step (iv) into at least two cuts essentially consisting of at least one unreacted material (116) and the middle distillate fraction (117), and (vi) hydrotreating the obtained middle distillate fraction (117). |
