Summary: | A method for controlling ethylene oxidation uses ethylene and oxygen, in conjunction with a silver based catalyst, a moderator and a co-moderator, to form ethylene oxide. When controlling the ethylene oxidation reaction, the moderator concentration is maintained constant within a comparatively narrow operative concentration range and the co-moderator concentration is varied within a comparativelywider operative concentration range, to optimize a catalyst property such as the catalyst activity and/or the catalyst selectivity. |
