Title: Zeolite for gas adsorption and its production and adsorption and separation of gas using the same
Inventor: SUZUKI TAKASHI
IPC: B01D53/02
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To produce zeolite having a high nitrogen absorption, a high separation coefficient of nitrogen/oxygen and a high separation efficiency by exchanging a part or all of ion exchangeable cations of a type A zeolite with silver ions. SOLUTION: An NaA type zeolite consisting essentially of sodium or a CaA type zeolite consisting essentially of calcium is immersed in a silver salt solution to exchange 10-100% of sodium ions or calcium ions with silver ions. Thereby, a zeolite for gas adsorption is obtained. The amount of the exchanged silver ions is regulated by regulating the concentration of the silver salt and temperature and time of the exchange reaction. The resultant zeolite for gas adsorption can be used to carry out the separation of a nitrogen/oxygen mixed gas, separation of nitrogen from a nitrogen/methane mixed gas, separation of the nitrogen from a nitrogen/argon mixed gas, removal, etc., of gaseous carbon dioxide fromair.
