ABSTRACT:
This invention relates to a process for preparing an ethylene oxide catalyst by depositing silver and one or more alkali metal promoters on an alpha alumina carrier in which a fired carrier body is impregnated with a source of titania in a liquid medium that upon heating yields titania and is then calcined to generate titania uniformly dispersed in the carrier in an amount of up to about 10 percent by weight, basis the total weight of the carrier, and subsequently drying the carrier having said silver and alkali metal supported thereon.
