US Patent:

62003666, Mar 13, 2001
Filed:

Sep 1, 1999
Appl. No.:

9/388105
Inventors:

Martin Bulow - Basking Ridge NJ
Chang Jie Guo - Bridgewater NJ
Dongmin Shen - Berkeley Heights NJ
Frank R. Fitch - Bedminster NJ
Arthur I. Shirley - Piscataway NJ
Virginia A. Malik - Linden NJ
Assignee:

The BOC Group, Inc. - Murray Hill NJ
International Classification:

B01D 53047
US Classification:

95101
Abstract:

Ethene is separated from a gas mixture containing ethane by a pressure swing adsorption process carried out at a temperature in the range of about 50 to about 200. degree. C. , wherein the adsorption step of the process is conducted by passing the gas mixture through an adsorption zone containing type A zeolite whose exchangeable cations are preferably made up of at least about 60 but not more than 75% sodium ions and more than 25 and up to about 40 percent potassium ions.

International Classification:

B01D 5304
B01D 53047
US Classification:

95101
Abstract:

Carbon dioxide is separated from gaseous hydrocarbons by a cyclic adsorption process using at a temperature in the range of about -50 to about 200. degree. C. , wherein the adsorption step of the process is conducted by passing the gas mixture through an adsorption zone containing carbon molecular sieve or type A zeolite whose exchangeable cations are made up of about 50 to about 90% sodium ions and about 10 to about 50 percent potassium ions.
