    摘要： 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.

    摘要： The invention relates to a carrier for a thin layer and a method for the analysis of molecular interactions on and/or in such a thin layer. A thin layer disposed on a carrier is illuminated with electromagnetic radiation from at least one radiation source and a reflected radiation part on boundary surfaces of the thin layer is detected by means of an optoelectronic converter that converts the detected radiation into a frequency- and intensity-dependant photocurrent. A reading voltage is applied to the optoelectronic converter. By changing the reading voltage, the spectral sensitivity of the optoelectronic converter is varied such that a substantially constant photocurrent is obtained. Alternatively or in addition to varying the spectral sensitivity by changing the reading voltage, the reflected radiation part is detected with an optoelectronic converter that is designed as a sensor layer in the carrier. The carrier is particularly characterized in that it comprises a substrate on which at least one sensor layer with optoelectronic properties is disposed.
