Abstract

A process to reduce the acidity of acidic crude oils for preventing corrosion during processing of the crude oils, including transferring through pipe lines, tanker ships and tank vehicles. Crude oil having substantial amount of organic acid, in particular, naphthenic acid compounds is contacted with supercritical water and a catalyst for deacidification. A treated crude oil product has lower amounts of organic acid compounds than the original crude oil.
