NOx的氨还原对大型发生源而言虽已通用,但对小型发生源却有许多不便。这里叙述有关不需要任何还原气,以催化剂载体,活性碳自身作还原剂的简便催化剂。此外,在NH。等还原气通过这种催化剂时,碳不消耗,表面反应可在较低的温度下进行。既是载体也是还原剂的活性碳,可以采用煤系活性碳。这里以岛津制作所产的30～60目A—3型活性碳为例。在这种活性碳载上组成为5.0％Co—2.8％La_2O_3—0.66％Pt
Ammonia NOx reduction Although common to large sources, there are many inconveniences to small sources. Described here does not require any reduction of gas to the catalyst carrier, activated carbon itself as a simple catalyst reductant. In addition, at NH. When reducing gas passes through such a catalyst, the carbon is not consumed and the surface reaction can proceed at a lower temperature. Both the carrier and the reducing agent is activated carbon, you can use coal-based activated carbon. Shimadzu produced here to produce 30 to 60 mesh A-3 type activated carbon as an example. In this activated carbon on the composition of 5.0% Co-2.8% La 2 O 3 - 0.66% Pt
