Abstract
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 hr−1 and an hydrogen treat rate up to 200 Nm3/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.

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 hr−1 and a hydrogen treat rate up to 200 Nm3/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 525° C., wherein the feedstock has an aromatic content ranging from 3 to 30% by weight.
A process for producing a white oil having an initial boiling point of higher than 310° 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 hr−1 and a hydrogen treat rate up to 200 Nm3/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 170 to 325° C. and a final boiling point within the range from 375 to 525° C., wherein the feedstock has an aromatic content ranging from 3 to 30% by weight wherein the white oil has an aromatic content below 500 ppm by weight.
