Abstract
Provided is a method for reducing the amount of organic acids in a hydrocarbon oil fraction by hydrogenating the organic acids in the hydrocarbon oil fraction under mild conditions. Provided is a new method able to overcome the problem of organic-acid-induced corrosion during the process of distillation, by using hydrogen or a hydrogen-containing mixed gas and a hydrogenation catalyst to subject the organic acids in the hydrocarbon oil fraction to hydrogenation at an appropriate temperature and pressure, thereby converting the same to hydrocarbons and so reducing the amount of organic acids in the hydrocarbon oil fraction.
