Zinc cation exchanged lithium X-zeolite for nitrogen adsorption |
摘要 |
The present invention is directed to an at least binary exchanged X-zeolite having lithium and zinc cations in a ratio of preferably 5% to 40% zinc and 50% to 95% lithium, wherein the sum of the lithium and zinc ion exchange is at least 65% of the exchangeable ion content. Theses adsorbents are useful in a process for separating nitrogen from gas mixtures containing nitrogen and less strongly adsorbed components such as oxygen, hydrogen, argon or helium.
