Title:

CATALYST CARRIER AND PROCESS FOR PREPARING THE CATALYST CARRIER

Document Type and Number:

Japanese Patent JP2013063426

Kind Code:

A

Abstract:

To provide a process for preparing a catalyst carrier, which can keep the high level of selectivity when olefin oxide is produced by reacting olefin with oxygen.

The process for the preparation of a carrier comprises: a step of forming a mixture comprising (a) from 50 to 95 weight percent of a first particulate α-alumina having a median particle size (d₅₀) of from 5 to 100 mum, (b) from 5 to 50 weight percent of a second particulate α-alumina having a d₅₀ which is less than the d₅₀ of the first particulate α-alumina and which is in the range of from 1 to 10 μm, and (c) an alkaline earth metal silicate bond material, weight percent being based on the total weight of α-alumina in the mixture; and a step of firing the mixture to form the carrier.
