The present invention relates to a method for preparing a polyether amine catalyst, and polyether amine. A polyether amine catalyst is a supported metal catalyst; γ-Al.sub.2O.sub.3 is used as a carrier; basic cupric carbonate, basic nickel carbonate and basic cobalt carbonate are used as precursors of supported metals; and the polyether amine catalyst is prepared by performing twice adsorption roasting and once reduction by means of an equivalent-volumetric impregnation method. Easier decomposition is achieved by using basic carbonate, and only water and carbon dioxide are generated, such that processes and costs for treating waste gases can be saved. By using the polyether amine catalyst to prepare polyether amine, a conversion rate and primary amine selectivity can be improved, and the color of products can be reduced. Therefore, the obtained polyether amine can have higher activity and wider application.
