| 摘要 |
The present invention provides for methods and compositions for gas separation and purification utilizing a metallo-organic polymer adsorbent in processes for separating carbon dioxide, water, nitrogen oxides and hydrocarbons from gas streams. The metallo-organic polymer adsorbent composition has the formula:wherein R represents an organic spacer selected from the group consisting of an organic cyclic or acyclic compound; L represents a ligation group substituted on the organic spacer selected from the group consisting of carboxylate group, -C(=O)O-; dithiocarboxylate group, -C(=S)S-; and beta-diketonate group, -C(=O)C(R')=C(-O-)-, wherein R'=H, or an aliphatic or aromatic group; M represents a transition metal or a rare earth metal selected from the group consisting of I to VIIB and VIII metals; m is the oxidation state of transition metal; and n is the number of the ligation group substituted on the organic spacer.
