Title:
触媒担体の製造方法および触媒担体
Document Type and Number:
Japanese Patent JP5667778
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a catalyst carrier that is suitable as a catalyst carrier such a catalyst for catalytic partial oxidization reaction, has high heat resistance and that is stable over a long period.SOLUTION: This method for producing a catalyst carrier formed from a silica-carrying alumina molded body includes the following step (I), (II) and (III): (I) preparing the alumina molded body in the order of the following processes: (1) a process of mixing transition alumina powder having rehydration properties with water and molding them to obtain a molded body; (2) a process of retaining the obtained molded body in a wet atmosphere or steam at not lower than 110°C and not higher than 200°C to obtain a rehydrated molded body; and (3) a process of firing the rehydrated molded body at not lower than 900°C; (II) making the obtained alumina molded body carry silica to obtain a silica-carrying alumina molded body having silica concentration of 0.1-5 mass% in SiOconversion; and (III) calcining the obtained silica-carrying alumina molded body.
