Nitrogen adsorption with a divalent cation exchanged lithium x-zeolite |
摘要 |
<p>The present invention is directed to a process for separating nitrogen from gas mixtures containing nitrogen and less strongly adsorbed components such as oxygen, hydrogen, argon or helium by use of a crystalline X-zeolite having a zeolitic Si/Al ratio≤1,5 and an at least binary ion exchange of the exchangeable ion content with at least 70 % lithium and with at least 5 % zinc, and to the X-zeolite itself. Preferably the zeolite is ion exchanged with approximately 15 - 30 % of zinc and 85 - 70 % lithium.</p> |
