A method of installing an epoxidation catalyst in a microchannel reactor comprising depositing a Group 11 metal, especially silver or a cationic Group 11 metal component, especially silver complexed with ethylene diamine, 1,2-propylene diamine, 2,3-butylene diamine or ethanol amine, on at least a portion of the walls of the microchannel reactor, depositing one or more promoters, especially rhenium, tungsten, molybdenum, chromium or mixtures thereof, and additionally an alkali metal, especially lithium, potassium, caesium or mixtures thereof, prior to, together with or subsequent to deposition of the Group 11 metal or the cationic Group 11 metal component. Also disclosed is a process for the epoxidation of an olefin comprising reacting a feed comprising the olefin and oxygen in the presence of the epoxidation catalyst; and a process for the preparation of a 1,2-diol, a 1,2-diol ether, a 1,2-carbonate or an alkanol amine comprising reacting a feed of an olefin and oxygen in the presence of the epoxidation catalyst. |
