The invention provides a hydrogenation method for pyrolysis gasoline, wherein the pyrolysis gasoline which is by-produced in the ethylene production process is preheated and then enters a fixed bed hydrogenation reactor, the reactor is filled with nickel-molybdenum-zinc series hydrogenation catalysts, and after hydrogenation, the material is sent to the second-stage hydrogenation reactor; the catalysts prepared by using the nickel-containing carrier having the specific crystalline form prepared by the hydrogenation method for the pyrolysis gasoline can greatly improve the utilization ratio ofactive metal and reduce the preparation difficulty of the catalyst, and a synergistic action of selected active components can be added to play a synergistic effect to obtain active, selective and stable first-stage hydrogenation catalyst for the pyrolysis gasoline.
