The structure and surface properties of alumina is adjusted by doping phosphor into it. A Co-Mo-Ni supported catalyst is prepared with the doped alumina as support. The catalyst exhibits medium acidity and good dispersion of active components. With the catalyst used in the hydrogenation of pyrolytic gasoline at the second stage the sulfur content and bromine value of hydrogenated product can be less than 0.5 μg/g and 0.5 g Br/(100 g), respectively, and the pressure difference inside the reactor has no obvious increase.
