Nitrogen adsorption process. |
摘要 |
<p>The invention relates to a process for adsorption of nitrogen from nitrogen-containing gases using faujasite-containing compositions in which the original hydrogen or monovalent forms are ion exchanged to their polyvalent form and then dehydrated in such a manner as to result in a preponderence of its polyvalent ions in a dehydrated/dehydroxylated state while maintaining substantially the same zeolite content. The resulting compositions, whose cations contained in the faujasitic portion are substantially in their dehydrated/dehydroxylated state, have been found to have surprisingly high selectivities and capacities for the separation of air into nitrogen and oxygen.</p> |
