Influence of composition (Pd) In-, Co-containing aluminia- and zirconia-based catalysts on simultaneous reduction of nitrogen(I, II) oxides by CO

Abstract

It is shown that binary In-, Co-oxide supported catalysts show high activity in the reactions of simultaneous reduction of nitrogen(I, II) oxides by CO, which depends on the nature support (Al 2 O 3 , ZrO 2), a sequence of the active components introduction. Structured Pd-containing In-, Co-oxide catalysts are characterized by high activity, moisture and sulfur resistance, low content of Pd (0.1) and can be used for complex purification of waste gases from nitrogen oxides and CO.
