US 9,127,215 B2 · Method for reducing the amount of organic acids in a hydrocarbon oil fraction

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.

A method of reducing an amount of an organic acid in a hydrocarbon oil fraction, comprising the step of:

hydrogenating the hydrocarbon oil fraction using a hydrogen gas supplied at a H2/oil ratio of about 1-100 (NL/L) in the presence of a hydrogenation catalyst under conditions of a temperature of about 300-400° C. and a pressure of about 3-15 kg·f/cm2,
wherein the hydrogen gas is a gas mixture comprising about 25-75 wt % of hydrogen,
wherein the hydrogenation catalyst is a spent catalyst having activity among catalysts employed in a refining process, and
wherein the amount of the organic acid in the hydrocarbon oil fraction is reduced by about 70% or more.
