摘要
制备以堇青石蜂窝陶瓷为载体,以Cu,Cu-NiO、Cu—NiO,La2O3、Cu-NiO—Ce203为活性组分,以尿素为还原剂,选择催化还原氮氧化物的催化剂,并对催化剂的活性在423,623K范围内进行了评价和比较,筛选出活性较高、较有研究前景的催化剂,
With ceramic cordierite honeycomb as a carrier and Cu,Cu-NiO, Cu-NiO-La203 or Cu-NiO-Ce203 as active components, several catalysts were synthesized for the selective catalytic reduction of nitrogen oxide with urea as reductive agent. The activity of these catalysts was evaluated and compared in the range of 423 K and 623 K. The reasearch result indicates that the catalysts have high activity.
