The invention provides a process for the production of paraffin fractions by special hydrocracking comprising the treatment of a feedstock with hydrogen at 160-420°C temperature and 5-100 bars pressure in the presence of a heterogeneous catalyst applied on a carrier, wherein the volumetric ratio of hydrogen to feedstock is 200-2000 Nm 3 /m 3 and the hourly feedstock load is up to 10 m 3 feed/m 3 catalyst, and wherein - the feedstock comprises fatty acids and fatty acid esters; - the process is carried out in the presence of a sulfidizing agent to maintain the sulfidized state of the sulfide catalyst at a constant level; and - the process is carried out in the presence of an agent inhibiting oxidation and/or gum formation as indifferent material for controlling the reaction. The invention further provides four paraffin fractions obtained by the process.
