    Abstract: A process for removing essentially naphthenic acids from a crude oil which has not previously been fractionated by distillation, or from which only a naphtha fraction has been distilled. The crude oil is hydrogenated at 1-50 bars and 100-300.degree. C. over a catalyst of the kind used for hydrogenation of atmospheric residue oils. As a catalyst, especially Ni--Mo or Ni--Co deposited on alumina as a carrier material is used.
