The invention belongs to the technical field of catalysts for alkene epoxidation and provides a method for preparing an alpha-alumina carrier of a silver catalyst for alkene epoxidation. The preparation method comprises the steps as follows: I) preparing a precursor solid mixture of the alpha-alumina carrier of the silver catalyst for alkene epoxidation; II) adding an adhesive to the precursor solid mixture to obtain a mixture; III) uniformly kneading the mixture obtained in step II) and performing extrusion molding to obtain a molded body; and IV) directly calcining the molded body obtained in step III) under the air condition without drying to prepare the alpha-alumina carrier. The preparation method is simpler, energy-saving and time-saving while guaranteeing the performance of the silver catalyst and the carrier.
