Abstract
A simplified method of operating an alkylene oxide production process that utilizes a high efficiency silver catalyst is shown and described. The method accounts for declining catalyst activity that occurs as the catalyst ages by making alternating changes to the reaction temperature and an overall chloriding effectiveness parameter.
