The present invention discloses a method for producing an ethylene cracking material through dry gas hydrogenation. According to the method, olefin-containing dry gas and optional supplemented hydrogen enter a fixed bed hydrogenation reactor in a co-current flow manner, and contact a hydrogenation catalyst under a hydrogenation process condition, a reaction is performed, and the obtained reaction products are separated to obtain the dry gas having the saturated olefin; and the hydrogenation reactor comprises four reaction sections, and according to the sequence of the contact between the material and the catalyst, the law of the hydrogenation activity metal contents in the catalysts in each reaction section is the low content, the high content, the low content and the high content. According to the present invention, with the method, the relatively average reaction rate of the inlet section of the catalyst bed layer is reduced, the problem that the relatively average reaction rate of the inlet section of the catalyst bed layer is high is solved, the difference among the average reaction rates of each section of the bed layer is substantially reduced, and the relatively average reaction rates of each section are uniform; and with the method, the deep oxygen removal can be ensured.
