Abstract
The present invention provides a method of separating ethylene or ethane from a mixed gas containing ethylene and ethane using hydroquinone. According to the present invention, hydroquinone selectively forms a clathrate with ethylene, and thus it is possible to separate ethylene with high yield and purity through a single process.
Claims6
A method for separating ethylene or ethane, comprising:
- forming an ethylene-hydroquinone clathrate by bringing a mixed gas containing ethane and ethylene into contact with hydroquinone;
- and
- separating ethylene from the clathrate.
