    Abstract: The invention relates to a method and a device for putting into service a reactor and a catalyst, especially a catalyst and a reactor for dehydrogenating a hydrocarbon-containing charge in a plant for producing olefins. Before being put into service, the catalyst and the reactor run through a plurality of oxidation and reduction phases, thereby releasing the chloride contained in the catalyst. The released chloride is carried off into the atmosphere in a gaseous form.

    Abstract: The invention relates to a method and a device for the controlled regeneration of a catalyst and of a fired reactor, especially a catalyst and a reactor in a plant for producing olefins from a hydrocarbon-containing charge. During the regeneration phase of the catalyst for recovering the catalytic activity, the burners of the reactor are switched off. After the regeneration phase, the burners are re-ignited by means of inbuilt pilot burners. The pilot burners are monitored and their capacity is adjusted in such a manner that the heat loss of the reactor during the regeneration phase of the catalyst is compensated for.
