Patent
·
OSTI ID:6021258
This patent describes a process for the production of ethylene oxide wherein ethylene is contacted in the vapor phase with an oxygen-containing gas at ethylene oxide forming conditions at a temperature ranging between about 180/sup 0/C and 330/sup 0/C in the presence of a silver metal-containing catalyst, the improvement which comprises using a catalyst comprising a catalytically effective amount of silver, a promoting amount of alkali metal, a promoting amount of rhenium and a promoting amount of a rhenium co-promotor selected from sulfur, molybdenum, tungsten, chromium and mixtures thereof supported on a suitable support.
