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.
