| Abstract |
Disclosed is a hydrorefining process which is characterized in that an oil to be processed which contains an oxygen-containing hydrocarbon compound and a sulfur-containing hydrocarbon compound is brought into contact, in the presence of hydrogen, with a catalyst which contains a porous inorganic oxide containing two or more elements selected from aluminum, silicon, zirconium, boron, titanium and magnesium, and one or more metals selected from group 6A and group 8 elements of the periodic table and loaded on the porous inorganic oxide, at a hydrogen pressure of 2-13 MPa, at a liquid hourly space velocity of 0.1-3.0 h<sup>-1</sup>, at a hydrogen/oil ratio of 150-1500 NL/L, and at a reaction temperature of 180-380˚C. |
