ABSTRACT:
A process for preparing silver-containing catalysts and their carriers for the production of ethylene oxide via ethylene oxidation and also to the applications of said catalysts in producing ethylene oxide.
Commercial trihydrated .alpha.-alumina, boehmite, carbonaceous materials, a fluxing agent, fluoride and a binder are mixed with water, kneaded and extruded to form strips which are cut and shaped. The shaped bodies are dried, calcined and converted to a .alpha.-alumina bodies i.e., carriers. This process is characterized by using trihydrated .alpha.-alumina, boehmite alumina and carbonaceous materials which have a good matching of particle sizes and proportions in preparing alumina carriers with the following pore structure:
