Abstract: The present invention relates to a catalyst for the epoxidation of alkenes, comprising silver, rhenium, cesium, lithium, tungsten and sulfur on a support. The present invention further relates to a process for producing the catalyst and the use of the catalyst for the oxidation of alkylenes to alkylene oxides. In addition, the present invention relates to a process for preparing ethylene oxide from ethylene, which comprises the oxidation of ethylene with oxygen in the presence of said catalyst.
