Abstract (en)
A process for preparing gas oil and base oil by subjecting a part of a Fischer-Tropsch product to hydroconversion/hydroisomerisation at a conversion in the range of between 50 and 90 wt%, a hydrogen partial pressure between 45 and 75 bara, a temperature between 280 and 425 °C, using a catalyst comprising Pt and/or Pd, ASA, and no or hardly any zeolite; subjecting another part of the Fischer-Tropsch product to hydroconversion/hydroisomerisation at a conversion between 30 and 60 wt%, a hydrogen partial pressure between 20 and 55 bara, a temperature between 175 and 375 °C, using a catalyst comprising Pt and/or Pd, ASA, and 0.1-15 wt% wt% zeolite; distilling a fraction boiling in the gas oil range, a fraction boiling in the distillate base oil range, and a heavier fraction, from a combination the products of the hydroconversion/hydroisomerisation steps; recycling at least a part of the heavier fraction; performing a pour point reducing step on the fraction boiling in the distillate base oil range.
