The present invention relates to a method for removing sulfur compounds and sulfone compounds in catalytic cracked hydrocarbon having a high sulfur content by performing selective oxidative desulfurization and hydrosulfurization process. According to various examples of the present invention, only sulfur component is removed through post treatment of sulfone compounds produced after selectively oxidizing non-biodegradable sulfur compounds, thereby alleviating reported chronic disadvantage (reactant loss) of the post treatment process (elution) of the selective oxidative process, simplifying the process and improving the efficiency of the process for removing sulfur compounds and sulfone compounds. Accordingly, the present invention can achieve the effect of being usefully applied in removing sulfur compounds and sulfone compounds in manufacturing light gas oil.
