N_2O催化分解——CuY分子筛的催化活性

N_2O Catalytic Decomposition Catalytic Activity of CuY Molecular Sieve

用离子交换、等体积浸渍法分别制备了ＣｕＹ 分子筛系列催化剂， 考察了它们对Ｎ２Ｏ 分解的催化活性。结果表明： ＣｕＹ 催化剂的活性， 随着Ｃｕ２ ＋ 交换度的增大而提高； 焙烧温度对催化性能有显著影响； 离子交换法制备的ＣｕＹ 活性显著优于浸渍法。

The CuY molecular sieve series catalyst was prepared by using the ion exchange and equivalent volume soak method. Its activity for N 2O decomposition was investigated. The result shown that the CuY catalytic activity is increasing as the Cu 2+ exchange extent increasing. The effect of calcination temperature on catalytic activity is obvious. Catalytic activity of CuY prepared by ion exchange method is high than the soak method.
