PURPOSE: An organic acid reduction method from hydrocarbon oil is provided to use the decarboxylation reaction of organic acid using hydrogen or hydrogen containing gas, and a catalyst. CONSTITUTION: An organic acid reduction method from hydrocarbon oil comprises a step of supplying hydrogen gas to the hydrocarbon oil under the presence of a hydrogenation catalyst for hydrogenating the hydrocarbon oil. The supplying process is performed at 300-400 deg C in the pressure of 3-16kgf/square centimeter. The hydrocarbon oil is selected from the group consisting of raw crude oil, bio-fuel, atmospheric residues, and advance process oil. The raw crude oil or bio-fuel is hydrogenated at 300-400 deg C after being desalinated. The hydrogenation catalyst is selected from a gas oil hydro-desulfurization catalyst, a heavy metal absorption catalyst for the desulfurization of the atmospheric residues or the advance process oil, a hydro-desulfurization catalyst, a hydro-denitrogenation catalyst, or their compounds.
