    Abstract: 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:



    Hydrodearomatizing the feedstock at a temperature ranging from 150 to 220° C. and at a pressure ranging from 20 to 150 bars, in order to provide a dearomatized product;
    Hydroisomerizing the dearomatized product at a temperature ranging from 250 to 320° C. and at a pressure ranging from 40 to 60 bars in the presence of a catalyst based on platinum or palladium, in order to provide an isomerized product;
    Hydrodearomatizing the isomerized product at a temperature ranging from 150 to 220° C. and at a pressure ranging from 20 to 150 bars, in order to provide an isomerized and dearomatized product.
