摘要： The present invention provides a process to prepare middle distillates and base oils from a Fischer-Tropsch product, by (a) subjecting the Fischer-Tropsch product to a hydroprocessing step in the presence of a catalyst comprising a molecular sieve with a pore size between 5 and 7 angstrom and a SiO2/AlO3 ratio of at least 25, preferably from 50 to 180 and a group VIII metal to obtain a mixture comprising one or more middle distillate fractions and a first residual fraction and a naphtha fraction; (b) separating the mixture as obtained in step (a) by means of atmospheric distillation into one or more middle distillate fractions, a first residual fraction and a naphtha fraction;(c) separating the first residual fraction by means of vacuum distillation into at least a distillate base oil fraction and a second residual fraction.

摘要： The invention relates to a process for the conversion of a paraffinic feedstock that comprises at least 50 wt% of compounds boiling above 370 °C and which has a paraffin content of at least 60 wt%, an aromatics content of below 1 wt%, a naphthenic content below 2 wt%, a nitrogen content of below 0.1 wt%, and a sulphur content of below 0.1 wt%, the process comprising: a) subjecting the paraffinic feedstock to a hydroprocessing step to obtain an at least partially isomerised feedstock; b) separating the at least partially isomerised feedstock into one or more middle distillate fractions and a first residual fraction, wherein step a) is carried out by contacting the paraffinic feedstock with a first catalyst having hydrocracking and hydroisomerising activity and then with a second catalyst having hydrocracking and hydroisomerising activity, wherein the second catalyst is more active in hydroisomerisation and less active in hydrocracking than the first catalyst.
