Process for the treatment of catalysts or catalyst supports in onenDevice, the treatment being carried out continuously in the mannernis that during the entry of the catalyst or the catalyst carrierninto the device and / or during its exit from the devicenchange physical and / or chemical conditions and / or the catalystnor the catalyst carrier in the device by zones (5, 6, 7) differentnphysical and / or chemical conditions is transported.n n n Compared to the discontinuous process previously practiced, there is the advantage that there are no long cooling and heating periods during the treatment and that material of more uniform quality is produced. |
