Sulfur dioxide and/or sulfur dioxide hydrate absorbent |
摘要 |
Disclosed is an sorbent for removing sulfur dioxide (SO2) contained in combustion flue gases or in the atmosphere by using a diamine-based ionic liquid or a diamine compound supported by a polymer resin. To be specific, the present invention relates to a method of using a tertiary diamine compound immobilized on a polymer surface as a SO2 sorbent and also relates to a novel sorbent for absorbing or adsorbing a sulfur dioxide hydrate (SO2.H2O) formed by a bond between SO2 and water. |
