Hydrocarbon separation method

A method of separating hydrocarbons (such as short chain paraffins and olefins) from non-hydrocarbon gases using short-cycle time concentration swing adsorption processes. The hydrocarbons are adsorbed from the gaseous stream on water-stable highly siliceous nanoporous materials, e.g., such as of al...

Beschreibung
Zusammenfassung:	A method of separating hydrocarbons (such as short chain paraffins and olefins) from non-hydrocarbon gases using short-cycle time concentration swing adsorption processes. The hydrocarbons are adsorbed from the gaseous stream on water-stable highly siliceous nanoporous materials, e.g., such as of aluminum-deficient faujasite-type zeolites, then desorbed from the adsorbent in the presence of steam. Optionally, the steam is desorbed from the adsorbent through the use of air or inert gas or a recycle of the non-adsorbed gas.
