Abstract
In results of testing a series of the metal-containing zeolite catalysts based on different structure types zeolites (Y, M, pentansil), Ме/zeolite, zirconia and (zeolite+ZrO2, Me = Ce, Co, Fe, Cr) in the reaction of nitrogen (I) oxide decomposition was found that the most active Fe-containing catalysts over the zeolitic base are characterized by the presence of strongly acidic sites on their surface, activity of Co-containing catalysts depends on quantity of a gated in cobalt. The temperature of nitrogen (I) oxide elimination reaction on Fe zeolite catalysts was found to decrease by 70–150°С in the presence of a reductant – light alkanes (C3–C4) or carbon monooxide. Upon oxygen excess, N2O conversion high degrees (90–94%) were attained at lower by 50–150°С temperatures if hydrocarbons used and the catalysts’ activity being in correlation with the presence of strong acidic B-sites on their surface.
