摘要：This invention relates to catalyst carriers to be used as supports for metal andmetal oxide catalyst components of use in a variety of chemical reactions. Morespecifically, the invention provides a process of formulating a low surface area alphaalumina carrier that is suitable as a support for silver and the use of such catalyst inchemical reactions, especially the epoxidation of ethylene to ethylene oxide. A precursorfor a catalyst support comprises an admixture of an alpha alumina and/or a transitionalumina; a binder; and either a solid blowing agent which expands, or propels a gas uponthe application of sufficient heat, and optionally contains talc and/or water solubletitanium compound.
