    Abstract: The present invention relates to processes for preparing propene from propane, comprising the steps: A) a feed gas stream a comprising propane is provided; B) the feed gas stream a comprising propane, if appropriate steam and if appropriate and 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, hydrogen, if appropriate carbon monoxide, carbon dioxide, steam and oxygen; C) the product gas stream b is cooled, if appropriate compressed and steam is removed by condensation to obtain a steam-depleted product gas stream c; D) the product gas stream c is contacted with a selective adsorbent which adsorbs propene selectively under the selected adsorption conditions to obtain a propene-laden adsorbent and a propene-depleted gas stream d2 comprising propane, methane, ethane, ethene and hydrogen, carbon monoxide and carbon dioxide; E) a propene-comprising gas stream e1 is released from the propane-laden adsorbent by pressure reduction and/or heating of the adsorbent.

    Abstract: The invention relates to a method for commercially obtaining propene from a gas flow containing propene and at least one additional hydrocarbon. Said method comprises the following steps; (a) the gas flow is brought into contact with an adsorber containing a porous metalorganic framework material containing at least one at least bidentate organic compound which is co-ordinately bound to at least one metal ion, said adsorber being charged with propene; and (b) the propene is released from the adsorber charged with the propene. The invention further relates to the use of a porous metalorganic framework material for commercially obtaining propene from a gas flow containing propene and at least one additional hydrocarbon.

    Abstract: La invención se relaciona con un método para producir propeno de propano. El método comprende los siguientes pasos: A) una corriente (a) de gas de alimentación que contiene propano se prepara; (B) I corriente (a) de gas de alimentación que contiene propano, se introduce opcionalmente con vapor de agua y opcionalmente, una corriente de gas que contiene oxígeno hacia una zona de deshidrogenación y luego el propano se deshidrogena para formar propeno, y una corriente (b) de gas de producto que contiene propano, propeno, metano, etano, eteno, hidrógeno, opcionalmente monóxido de carbono, dióxido de carbono, vapor de agua y oxígeno se obtiene; (C) la corriente (b) de gas de producto se enfría, opcionalmente se comprime y luego el vapor de agua se separa mediante consideración y se obtiene una corriente (c) de gas de producto agotada en vapor de agua; (D) la corriente (c) de gas de producto se lleva a contacto con adsorbedor selectivamente activo que adsorbe selectivamente propeno en las condiciones de adsorción seleccionadas, y un adsorbedor cargado con propeno y una corriente (d2) de gas agotada en propeno y que contiene propano, metano, etano, eteno e hidrógeno, monóxido de carbono y dióxido de carbono se obtienen; E) una corriente (e1) de gas que contiene propeno se librea del absorbedor cargado con propeno reduciendo la presión y/o calor del adsorbedor.
