    Abstract: The invention provides a process for hydrogenating streams in plants for producing alkenes by catalytic dehydrogenation of light alkanes, and also an apparatus for carrying out the process. The entire hydrocarbon stream to the dehydrogenation reactor, consisting of fresh and recycled alkane, is subjected upstream of the dehydrogenation reactor to a full hydrogenation of all unsaturated hydrocarbons present therein. This drastically reduces coke formation in the dehydrogenation reactor. The energy demand for the preheating of the reactant stream to reaction temperature is reduced since the energy released in the exothermic hydrogenation remains virtually fully in the hydrocarbon stream.

    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.

    Abstract: El objeto de la invencion es un procedimiento para la hidrogenacion completa de corrientes de sustancias en plantas para la produccion de alquenos por deshidrogenacion catalitica de alcanos livianos, asi como un dispositivo para la realizacion del procedimiento. Toda la corriente de hidrocarburo hacia el reactor de deshidrogenacion, que se compone de alcano fresco y alcano reciclado, es sometida todavia antes de entrar en el reactor de deshidrogenacion a una hidrogenacion completa de todos los hidrocarburos no saturados contenidos en ella. De este modo se alcanza reducir drasticamente la formacion de coque en el reactor de deshidrogenacion. La energia necesaria para el precalentamiento de la corriente de eductos a la temperatura de reaccion es reducida, puesto que la energia librada en la hidrogenacion exotermica permanece caso por completo en la corriente de hidrocarburo.

    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.
