1. A method for the preparation of a fluid having an initial boiling point and a final boiling point in the range of from 150 to 260° C. and comprising more than 80% by weight of isoparaffins and less than 50 ppm of aromatics and having a bromine index of less than 1 mg/Br/100 g of fluid, comprising the step of catalytically hydrogenating a feed comprising more than 85% by weight of oligomerized olefins, at a temperature from 115 to 195° C. at a pressure from 30 to 70 bar, and at a liquid hourly space velocity (LHSV) from 0.1 to 3.0 hr−1, wherein the method comprises three hydrogenation stages in three separate reactors, wherein the oligomerized olefinic feed is selected from tetrameric propylene cuts.
