摘要: 含氮有机物,如毗咤完全氧化的最终产物有如下两种情况:除CO2和H2O外,可以是N2,也可以是NOx.催化燃烧净化含氮有机污染物时,希望反应过程不生成或少生成NOx.这要求所用催化剂具有高的氧化活性,并抑制生成NOx.尽管已有实用催化剂的报道,但深入研究尚很不够.本文以毗咤氧化为探针反应,考察金属氧化物的氧化活性及NOx生成规律.

Abstract: Formation of nitrogen oxides in the oxidation of pyridine over different γ-Al2O3supported oxide catalysts has been studied in the temperature range of 200~700℃,The oxi-dation activity and the ability to control NOx formation were found to be decreased in the or-der :Ag-O>Cu-O>Mn-O>Cr-O>Fe-O>Co-O>Ni-O>V-O>Ce-O.NOx formation con-trol ability appeared in relation to the basicity of the catalyst surface.

Key words: pyridine, catalytic oxidation, supported metal oxide catalyst, NOx formation con-trol
