Process to obtain N-paraffins from vegetable oil

Process to obtain N-paraffins from vegetable oil in a mixture with mineral hydrocarbon oil, in the presence of a hydrogen stream, hydroconversion catalysts and operational conditions for hydroconversion reactions to obtain N-paraffins, wherein the process comprises:

• a) providing a first stream comprising a vegetable hydrocarbon oil in the C12-C14 range and/or natural fat;
• b) providing a second stream comprising a mineral hydrocarbon oil;
• c) mixing the first and second streams of (a) and (b);
• d) performing hydrotreatment of the mixture obtained in (c) in a hydroconversion reactor under temperatures in the range of 280° C. to 320° C., spatial velocity of 0.5 h−1 to 2 h−1, hydrogen load ratio of 200 NL of hydrogen/L of a 1000 NL hydrogen/L and pressure at 7 MPa to 15 MPa in the presence of a catalyst, hydrogen stream, pressure, and temperature and obtaining a third stream comprising hydrocarbons;
• e) directing the third hydrocarbon stream obtained in (d) to a rectifier to remove sulfide gas and ammonia;
• f) recovering the resulting effluent stream comprising N-paraffins in the C10-C13 range, in a content of above 98% in weight, and a boiling point at the range of kerosene's boiling point.
