Abstract

Adsorption of ethane/ethene, propane/propene and methane, ethane/ethene, propene mixtures was examined on 4A-zeolites K0·08Na0·92A, Ba0·2Na0·8A, Mg0·2Na0·8A and NaA by measurement of breakthrough curves. Separation of the alkenes and alkanes, especially dynamic capacities, the purity of the desorbates and yields of olefins, confirm the accepted transport mechanism of small alkenes in 4A-zeolites. It is possible to vary the blocking cations and the adsorption centres in the large cavities to obtain favourable conditions for a common separation of ethene and propene from crack-gases.
