Abstract
Official abstract text for this publication.
A method for producing the silica carrier which includes kneading fumed silica obtained by a combustion method, silica gel obtained by a gel method, and colloidal silica obtained by a sol-gel method or a water glass method, molding the resulting kneaded product, and calcining the resulting molded body. The silica carrier has, in the measurement of pore size distribution, mesopores with a pore size of 2 to 50 nm and macropores with a pore size of more than 50 nm and 1,000 nm or less.
First claim
Opening claim text (preview).
The invention claimed is: 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. 2. The method for producing a silica carrier according to claim 1 , wherein the calcining is at a temperature from 300 to 1,000° C.
