The invention is a process for producing a white oil having an initial boiling point of at least 300° C., the process comprising a step of catalytically hydrogenating a hydrocarbon feedstock at a temperature of from 80 to 190° C., at a pressure of from 50 to 160 bars, a liquid hourly space velocity of 0.2 to 5 hrand an hydrogen treat rate up to 200 Nm/ton of feed, the hydrocarbon feedstock having a sulphur content of less than 10 ppm by weight, an initial boiling point within the range from 150 to 350° C. and a final boiling point within the range from 350 to 550° C.

Process for the production of white oils

The invention is a process for producing a white oil having an initial boiling point of at least 250° C., the process comprising a step of catalytically hydrogenating a base oil feedstock at a temperature of from 120 to 210° C., at a pressure of from 30 to 160 bars and a liquid hourly space velocity of 0.2 to 5 hr, the base oil feedstock comprising less than 5 ppm by weight of sulphur.

The invention is a process for dearomatization and isomerization of a feedstock having less than or equal to 10 ppm by weight of sulphur, the process comprising:

Process for the production of fluids

A process for the production of a hydrocarbon fluid includes the step of catalytically hydrogenating a hydrocarbon cut in presence of both a dearomatization catalyst and a dewaxing catalyst in a single slurry reactor. A hydrocarbon fluid is also disclosed as being obtainable by the process.
