Abstract
There is provided a catalyst that is highly resistant to sulfur and nitrogen compounds and active for hydrogenation and shows a low hydrocracking rate and a long service life as well as a method of converting aromatic hydrocarbons in hydrocarbon oil containing sulfur and nitrogen compounds into saturated hydrocarbons by using such a catalyst. A method of hydrogenating aromatic hydrocarbons in hydrocarbon oil containing 80 wt % or more of a fraction having a boiling point of 170 to 390.degree. C. and said aromatic hydrocarbons is characterized in that the hydrocarbon oil is brought into contact with hydrogen in the presence of a catalyst containing clay minerals having principal ingredients of Si and Mg as carrier and at least one of the VIII-group metals of periodic table as active metal.
