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:
Hydrogen or methane gas pressure container having a minimum volume of 1 m3 a prescribed maximum filling pressure, has a filter through which oxygen, methane respectively, can flow during uptake. The filter has an adsorbent for adsorbing impurities selected from the group consisting of a higher hydrocarbon, ammonia, an odorous substance, hydrogen sulfide and a mixture of two or more of these substances. The pressure container and the filter comprise porous metal organic frameworks as adsorbent.
