A PROCESS FOR REMOVING ESSENTIALLY NAPHTHENIC ACIDS FROM A HYDROCARBON OIL.

摘要

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 atmopsheric residue oils. As a catalyst, especially Ni-Mo or Ni-Co deposited on alumina as a carrier material is used.
