OG exemplary drawing
 
1. A method for producing a silica carriers comprising kneading a fumed silica obtained by a combustion method, a silica gel obtained by a gel method, and a colloidal silica obtained by a sol-gel method or a water glass method, molding the resulting kneaded product, and calcining the resulting molded kneaded product,
wherein a blending amount of the fumed silica is from 5 to 50 parts by mass, a blending amount of the silica gel is from 40 to 90 parts by mass, and a blending amount of a solid content of the colloidal silica is from 5 to 30 parts by mass, based on total parts by mass of the silica carrier.
