| 摘要 |
This invention relates to a method of removing sulfur and nitrogen oxides by a dry process comprising passing a waste gas through a moving bed formed of a carbonaceous adsorbent in a direction transverse thereto to remove the sulfur oxides and adding ammonia to remove the nitrogen oxides, characterized in that in a system comprising n moving beds (n being an integer of at least 2), the waste gas is passed transversely through the first moving bed, mixed with ammonia outside the first moving bed, and then fed to the second moving bed, the similar procedure being repeated in order, and finally, the waste gas is passed transversely through the n-th moving bed, while the carbonaceous adsorbent is transported from the n-th moving bed to the first moving bed in order.
