Abstract
A method for periodically reactivating copper-containing catalyst material includes applying an oxygen-containing gas stream to the catalyst material for reactivation purposes. When the reactor is in the warm operating state, the application of the oxygen-containing gas stream to the catalyst material is interrupted when the monitored temperature of the catalyst material exceeds a maximum level which is a predeterminable tolerance level above a predetermined operating temperature. In cold-start phases, initially a mixture of a fuel and an oxygen-containing gas stream is fed to the catalyst material, until the monitored temperature of the catalyst material exceeds a predeterminable switch-over level, after which only the oxygen-containing gas stream is supplied. To keep the reactor warm after operation has ended, the reactivation can be activated each time the temperature falls below a further threshold level.
