摘要:
In a process for the separation of oxygen from a gas stream by adsorption, the improvement comprising using, as the adsorbent, a compound have the formula M.sub.x [M'(CN).sub.6 ].sub.ywherein M is an element having an atomic number of 21, 25 to 30, 39, 50, or 57 to 59;M' is an element having an atomic number from 24 to 27; andx and y are positive whole numbers such that the sum of the valence of M times x plus the valence of [M'(CN.sub.6)] times y is equal to zero.

A halogenated or sulfonated active carbon which has a high storage capacity for methane is provided from selected halogens in elemental form or solutions of such halogens or from solutions of sulfuric acid, fuming sulfuric acid, sulfur trioxide.
摘要:
Lithium/alkaline earth metal X zeolites in which the lithium:alkaline earth metal equivalent ratio is from about 95:5 to about 50:50 and lithium/alkaline earth metal A zeolites in which the lithium:alkaline earth metal equivalent ratio is from about 10:90 to about 70:30 are useful for separating oxygen and nitrogen from mixtures because they combine high adsorption capacity with high thermal stability.
摘要:
Pressure swing adsorption of air and other gas separation operations are carried out using specific preferred zeolite adsorbent compositions based on the symmetry of the framework atoms and cations therein. Specific SiO.sub.2 /Al.sub.2 O.sub.3 and cation/cation ratios for enhanced performance are identified. LiX adsorbent having a silica to alumina ratio on the order of 2.364 provides enhanced PSA performance.
