Catalytic Decomposition of N2O in Air Flows of Gas-Purification Systems in Radiochemical Industries

Catalytic decomposition of N 2 O in an air flow at at temperatures of ~420 to ~755 K in the presence of γ-Al 2 O 3 -based catalysts was studied. It was found that the degree of N 2 O decomposition in the presence of catalysts containing Mg, Ni, Co, and Fe does not exceed ~25% at a composite temperat...

Summary:Catalytic decomposition of N 2 O in an air flow at at temperatures of ~420 to ~755 K in the presence of γ-Al 2 O 3 -based catalysts was studied. It was found that the degree of N 2 O decomposition in the presence of catalysts containing Mg, Ni, Co, and Fe does not exceed ~25% at a composite temperature of ~735 K and contact duration of the gas flow with the composite of 5–6 s. It was shown that the Al 2 O 3 –2RuO 2 –400 composite enables a nearly full decomposition of N 2 O in an air flow at temperatures of 738–753 K and contact durations of 7–15 s.
