| 摘 要： | 采用USY分子筛为载体制备MnOx催化剂,考察了制备方法、前躯体、焙烧温度、催化组分负载量不同的情况下NH3选择催化还原NOx的能力,同时考察了添加Fe和Ce对Mn/USY催化剂脱硝性能的影响.结果表明,采用浸渍法负载10％的醋酸锰并在500℃下焙烧所制得的催化剂,在80～320℃范围内具有很高的催化活性;Fe、Ce的...

| Abstract: | Laboratory scale studies were conducted using low-temperature selective catalytic reduction(SCR) to reduce NOX with NH3.The catalytic used was USY(ultra-stable Y zeolite) supported MnOX catalyst which was prepared in the lab and the studies involved roasting temperature,Mn loading,Fe and Ce as metal additives and their influence on Mn/USY catalytic reduction of NOX.The experiment brought forth the optimum preparation condition involving use of impregnation for 10% manganese acetate loading and calcination t... |
