摘要： A method for enhancing the efficiency of a rhenium-promoted epoxidation catalyst is provided. Advantageously, the method may be carried out in situ, i.e., within the epoxidation process, and in fact, may be carried out during production of the desired epoxide. As such, a method for the epoxidation of alkylenes incorporating the efficiency-enhancing method is also provided, as is a method for using the alkylene oxides so produced for the production of 1,2-diols, 1,2-carbonates, 1,2-diol ethers, or alkanolamines.

摘要： A plant and process for producing alkylene oxides to control the production of silver chloride on a high efficiency silver catalyst is disclosed and described. The process involves reacting an alkylene and an organic chloride gas phase promoter with oxygen over the high efficiency silver catalyst. The sulfur concentration in the alkylene oxide reactor feed is controlled to reduce the production of silver chloride which acts as a catalyst poison.
