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 process for preparing a catalyst support, in which zirconium dioxide powder is mixed with a binder, if desired a pore former, if desired an acid, water and, if desired, further additives to give a kneadable composition and the composition is homogenized, shaped to produce shaped bodies, dried and calcined, wherein the binder is a monomeric, oligomeric or polymeric organosilicon compound. Suitable binders are monomeric, oligomeric or polymeric silanes, alkoxysilanes, aryloxysilanes, acryloxysilanes, oximinosilanes, halosilanes, aminoxysilanes, aminosilanes, amidosilanes, silazanes or silicones. The invention also provides the catalyst support which has been prepared in this way, a catalyst comprising the support and its use as dehydrogenation catalyst.
