还原剂

Amongst all the pos-combustion techniques, SCR method is one of the common practices. Yet, during the process of most SCR method, the corrosive reductants can lead to further pollution. As a result, developing alternative control technology is of the highest priority to effectively reduce NOx emission for the industry.

其中又以选择性触媒还原法较为普遍，但是其在还原过程中还原剂的溢散、腐蚀等问题还有待解决，所以再找寻更合适的技术是刻不容缓的事，因此如何有效降低氮氧化物之排放，对产业界乃是一项挑战。
