A high activity and high selectivity silver catalyst comprising silver and, optionally, one or more promoters supported on a suitable support material having the form of a shaped agglomerate. The structure of the shaped agglomerate is that of a hollow cylinder having a relatively small inside (bore)
A high activity and high selectivity silver catalyst comprising silver and, optionally, one or more promoters supported on a suitable support material having the form of a shaped agglomerate. The structure of the shaped agglomerate is that of a hollow cylinder having a relatively small inside (bore) diameter. The catalyst is made by providing the shaped material of a particular geometry and incorporating the catalytic components therein. The catalyst is useful in the epoxidation of ethylene.

That which is claimed is: 1. A process for manufacturing ethylene oxide, which process comprises: contacting, under suitable epoxidation process conditions, a feed stream comprising ethylene and oxygen, with a catalyst comprising silver deposited on a shaped support material having a hollow cylinde
That which is claimed is: 1. A process for manufacturing ethylene oxide, which process comprises: contacting, under suitable epoxidation process conditions, a feed stream comprising ethylene and oxygen, with a catalyst comprising silver deposited on a shaped support material having a hollow cylinder geometric configuration such that the length-to-outside diameter ratio of said shaped support material is in the range of from about 0.3 to about 2 and the internal diameter is in the range upwardly to 30 percent of the outside diameter of said shaped support material. 2. The process as recited in claim 1, wherein silver is present in a quantity in the range exceeding 15 weight percent of the total weight of the catalyst. 3. The process as recited in claim 2, wherein silver is present in a quantity in the range of exceeding 20 weight percent to and at most 50 weight percent, of the total weight of the catalyst. 4. The process as recited in claim 1, wherein the support material has a water absorption exceeding 40%. 5. The process as recited in claim 1, wherein the support material has a surface area in the range of from 0.03 m2/g to 10 m2/g. 6. The process as recited in claim 1, wherein the support material has a water absorption in the range of from 42.5% to 80%, and a surface area in the range of from 0.5 m2/g to 5 m2/g. 7. The process as recited in claim 1, wherein the length-to-outside diameter ratio is in the range of from about 0.5 to about 1.6 and the ratio of internal diameter to outside diameter is in the range of from 0.01 to 0.25. 8. The process as recited in claim 7, wherein the length-to-outside diameter ratio is in the range of from about 0.9 to about 1.1 and the ratio of internal diameter to outside diameter is in the range of from 0.02 to 0.2. 9. The process as recited in claim 1, wherein the outside diameter is in the range of from 4 to 16 mm, and the bore diameter is smaller than 3.5 mm. 10. The process as recited in claim 1, wherein the outside diameter is in the range of from 5 to 12 mm, and the bore diameter is in the range of from 0.1 to 3 mm. 11. The process as recited in claim 1, wherein the bore diameter is in the range of from about 0.2 mm to about 2 mm. 12. The process as recited in claim 1, wherein the catalyst further comprises a promoter component comprising a rare earth metal, magnesium, rhenium, or an alkali metal. 13. The process as recited in claim 1, wherein the catalyst further comprises a promoter component comprising rhenium, an alkali metal selected from lithium, potassium, rubidium and cesium, and, in addition, a rhenium copromoter comprising sulfur, molybdenum, tungsten or chromium. 14. The process as recited in claim 1, wherein the feed stream which is contacted with the catalyst, and which comprises ethylene and oxygen, has a concentration of carbon dioxide of at most 4 mole-%, relative to the total feed. 15. The process as recited in claim 1, wherein the feed stream which is contacted with the catalyst, and which comprises ethylene and oxygen, has a concentration of carbon dioxide of at most 2 mole-%, relative to the total feed. 16. The process as recited in claim 1, wherein the feed stream which is contacted with the catalyst, and which comprises ethylene and oxygen, has a concentration of carbon dioxide of at most 1 mole-%, relative to the total feed. 17. The process as recited in claim 1, wherein the feed stream which is contacted with the catalyst further comprises a moderating agent. 18. A method of using ethylene oxide for making ethylene glycol, an ethylene glycol ether or an 1,2-alkanolamine comprising converting ethylene oxide into ethylene glycol, the ethylene glycol ether, or the 1,2-alkanolamine, wherein the ethylene oxide has been obtained by the process for preparing ethylene oxide as recited in claim 1.
