The process described by this invention involves the hydroconversion of vegetable oils appropriately selected for the production of N-paraffins, through hydrotreatment of a stream of vegetable hydrocarbon oils in and/or natural fats that may be used in a pure state or in a mixture with mineral hydrocarbon oil. This mixture flow is submitted to the process of hydrotreatment, obtaining as a result, a product flow with an elevated content of N-paraffins in the range of C10-C-13. This process provides an alternative to the usual process that uses a mineral hydrocarbon oil load (petroleum kerosene of paraffin base) to produce C10-C13 N-paraffins that are raw materials for the production of detergents (LAB), being, therefore, especially advantageous for use in situations where kerosene is a limiting factor for producing N-paraffins, resulting in a product of good quality with a reasonable gain in the production of N-paraffins.

The invention claimed is: 1. 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.
