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.
