ABSTRACT:
A mixture is prepared by mixing alumina sol and activated alumina which contains not less than 60 Wt % of delta-alumina. The mixture is thereafter coated on a relatively small specific surface area monolithic catalyst carrier. After being dried, the coated carrier is fired to give a high specific surface area catalyst carrier.
