    Abstract: A process for preparing propene from propane, comprising the steps: A) a feed gas stream a comprising propane is provided; B) the fed gas stream a comprising propane, if appropriate steam and, if appropriate, an oxygenous gas stream are fed into a dehydrogenation zone and propane is subjected to a dehydrogenation to propene to obtain a product gas stream b comprising propane, propene, methane, ethane, ethene, carbon monoxide, carbon dioxide, steam, if appropriate hydrogen and, if appropriate, oxygen; C) product gas stream b is cooled, if appropriate condensed and steam is removed by condensation to obtain a steam-depleted product gas stream c; D) product gas stream c is contacted in a first absorption zone with a selective, inert absorbent which selectively absorbs propene to obtain an absorbent stream d1 laden substantially with propene and a gas stream d2 comprising propane, methane, ethane, ethene, carbon monoxide, carbon dioxide and hydrogen; E) if appropriate, the absorbent stream d1 is decompressed to a lower pressure in a first desorption zone to obtain an absorbent stream e1 laden substantially with propene and a gas stream e2 comprising propene, and gas stream e2 is recycled into the first absorption zone, F) from the absorbent stream d1 or e1 laden substantially with propene, in at least one second desorption zone, by decompression, heating and/or stripping the absorbent stream d1 or e1, a gas stream f1 comprising propene is released and the selective absorbent is recovered.

    Abstract: C 2 -C 30 -alkanes are dehydrogenated in a process in which (i) ethylbenzene is dehydrogenated to styrene in a first part process to give a hydrogen-containing offgas stream, and (ii) one or more C 2 -C 30 -alkanes are dehydrogenated in the presence of a heterogeneous catalyst in one or more reaction zones in a second part process to give the corresponding olefins, with a hydrogen-containing gas stream being mixed into the reaction gas mixture of the dehydrogenation in at least one reaction zone, wherein at least part of the hydrogen-containing offgas stream obtained in the dehydrogenation of ethylbenzene is mixed into the reaction gas mixture of the alkane dehydrogenation.

    Abstract: The invention relates to a process for preparing 4-vinylcyclohexene, which comprises the steps (A) providing an n-butane-containing feed gas stream, (B) feeding the n-butane-containing feed gas stream into at least one dehydrogenation zone and dehydrogenating n-butane to butadiene to give a product stream comprising butadiene, n-butane, possibly 1-butene and 2-butene and possibly water vapor and other secondary constituents, (C) feeding the product stream from dehydrogenation, if appropriate after separating off water vapor and secondary constituents, into a dimerization zone and catalytically dimerizing butadiene to give a product stream comprising 4-vinylcyclohexene, n-butane and possibly 1-butene, 2-butene and unreacted butadiene, and (D) separating off 4-vinylcyclohexene from the product stream from the dimerization and recirculating n-butane and possibly 1-butene, 2-butene and unreacted butadiene to the dehydrogenation zone.

    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.
