Hydrocarbon fluids are produced by hydrocracking a vacuum gas oil stream, fractionating and/or hydrogenating the hydrocracked vacuum gas oil. The fluids typically have ASTM D86 boiling point ranges within the range 100~C the range being no more than 75~C, they also have a naphthenic content greater than 60%, the naphthenics containing polycyclic materials, an aromatic content below 2% and an aniline point below 100~C. The fluids are particularly useful as solvents, for printing inks, drilling fluids, metal working fluids and as silicone extenders.

Selon l'invention, des liquides hydrocarbonés sont produits par hydrocraquage d'un flux de gazole sous vide, et par fractionnement et/ou hydrogénation du gazole sous vide hydrocraqué. Ces liquides présentent habituellement une plage de points d'ébullition selon ASTM D86 comprise entre 100 ·C et 400 ·C, cette plage n'étant pas supérieure à 75 ·C. Ils présentent en outre un teneur en composés naphténiques supérieure à 60 %, ces composés naphténiques contenant des matières polycycliques, une teneur en composés aromatiques inférieure à 2 %, ainsi qu'un point d'aniline inférieur à 100 ·C. Lesdits liquides sont particulièrement utiles comme solvants pour les encres d'impression, les liquides de forage et les liquides de travail des métaux, et comme huiles de dilution pour produits à base de silicone.
