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.
