Abstract

This invention relates to catalyst carriers to be used as supports for metal and metal oxide catalyst components of use in a variety of chemical reactions. More specifically, the invention provides a process of formulating an alpha alumina carrier that is suitable as a support for silver and the use of such catalyst in chemical reactions, especially the epoxidation of ethylene to ethylene oxide. The composition comprises at least one hydrated precursor of alpha alumina; an optional alpha alumina; and a binder. The composition is substantially free of seeding particles.
