  • Methods for conditioning an ethylene epoxidation catalyst and associated methods for the production of ethylene oxide
    Patent number: 11801493
    Abstract: Methods for conditioning an ethylene epoxidation catalyst are provided. The conditioning methods comprise contacting an ethylene epoxidation catalyst comprising a carrier, having silver and a rhenium promoter deposited thereon, with a conditioning feed gas comprising oxygen for a period of time of at least 2 hours at a temperature that is above 180° C. and at most 250° C., wherein the contacting of the ethylene epoxidation catalyst with the conditioning feed gas occurs in an epoxidation reactor and in the absence of ethylene. Associated methods for the epoxidation of ethylene are also provided.
    Type: Grant
