CO2 removal from gas using ionic liquid absorbents |
| 摘要 |
A process and method for separating CO<SUB>2 </SUB>from a gaseous stream such as natural gas. An ionic liquid comprising an anion having a carboxylate function is used as an adsorbent to selectively complex the CO<SUB>2 </SUB>yielding a gaseous stream with a greatly reduced CO<SUB>2 </SUB>content. The ionic liquid can then be readily be regenerated and recycled.
