The invention relates to a method for removing a nitride in inferior coker gas oil. According to the invention, catalysts comprise, from top to bottom, a protective agent, a demetalization agent, a desulfurizing agent and a denitriding agent; the denitriding agent uses an alumina-macroporous alumina-molecular sieve composite material as a carrier; a tungsten salt solution with a concentration of 0.01 g/cm<3> to 15 g/cm<3>, a molybdenum salt solution with a concentration of 0.01 g/cm<3> to 10 g/cm<3> and a nickel salt solution with a concentration of 0.01 g/cm<3> to 10 g/cm<3> are added into the carrier, and one or more selected from the group consisting of organosilicone, ethanol, propyl alcohol and butanol are employed for pretreatment of the carrier before dipping of the carrier; phosphorus and a citric acid additive are added into a carrier dipping solution, phosphorus content accounts for 0.001 to 0.1% of the weight of the carrier dipping solution, and citric acid content accounts for 0.001 to 30.0% of the weight of the carrier dipping solution. With the method provided by the invention, utilization efficiency of metal active components is improved, and the catalysts have the advantages of a low reaction temperature, a low reaction pressure and high activity.
