摘要: A method for producing hydrocarbon solvents having a sulfur content of less than 10 ppm, aromatic hydrocarbon content of less than 500 ppm, an initial boiling point higher than or equal to 300° C. and final boiling point lower than or equal to 500° C., for a fraction interval of a maximum of 100° C., and pour point lower than −25° C. according to the standard ASTM D5950, comprising of the following steps of: dewaxing of a hydrocarbon fraction having initial boiling point higher than 300° C. derived from the distillation of a gas oil fraction, hydrodearomatisation of all or part of the dewaxed effluent, in the presence of a catalyst comprising nickel on an alumina base, at a pressure ranging from 60 to 200 bar and a temperature ranging from 80° C. to 250° C., recovery of the dewaxed and dearomatised fraction, distillation in fractions of the dewaxed and dearomatised fraction, recovery of at least one 300° C.+ fraction having pour point lower than −25° C., this fraction having a distillation interval lower than 100° C.
