METHOD OF MAINTAINING THE VALUE OF AN ALKYLENE OXIDE PRODUCTION PARAMETER IN A PROCESS OF MAKING AN ALKYLENE OXIDE USING A HIGH EFFICIENCY CATALYST

摘要

Methods of reducing or maintaining the value of an alkylene oxide production parameter (such as alkylene oxide production rate) in a process of making an alkylene oxide by reacting an alkylene and oxygen over a high efficiency catalyst are shown and described. One method comprises reducing the concentration of oxygen in the reactor feed gas to reduce or maintain the value of the alkylene oxide production parameter.
