<p>The present invention relates to a desulfurization device with attached sulfur dioxide absorbents. The present invention relates to a tertiary amine-based sulfur dioxide absorbent having a nitrile (CN) functional group. In the present invention, a tertiary amine-based compound with the nitrile functional group has an outstanding capacity to absorb sulfur dioxide and is easy to be regenerated after absorbing sulfur dioxide, so the tertiary amine-based compound with the nitrile functional group can be used as sulfur dioxide absorbents.</p> |
