The present invention relates to the production of high value bio-chemicals, in particular bio-paraffins, bio-LPG, bio-naphtha, bio-jet and bio-distillates in an integrated bio-refinery from complex mixtures of natural occurring fats & oils.The present invention discloses a process for the production of such bio-chemicals, from natural occurring oil(s) containing acyl-containing compounds having 10 to 24 carbons including fatty acid esters and free fatty acids, and other components including impurities. Natural occurring oil(s) is(are) refined before treatment in a hydroprocessing step. The refining used in the present invention includes a hydrodynamic cavitation to remove impurities which might deteriorate the subsequent hydroprocessing step.
