Patent ID: 8067657

Claim:
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 C 12 -C 14 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 C 10 -C 13 range, in a content of above 98% in weight, and a boiling point at the range of kerosene's boiling point.
