Abstract

Catalytic decomposition of N₂O in an air flow at at temperatures of ~420 to ~755 K in the presence of γ-Al₂O₃-based catalysts was studied. It was found that the degree of N₂O 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 Al₂O₃–2RuO₂–400 composite enables a nearly full decomposition of N₂O in an air flow at temperatures of 738–753 K and contact durations of 7–15 s.

放射化学工业气体净化系统气流中N 2 O的催化分解

摘要

N中的催化分解₂在空气气流中在〜420至〜755 K的γ-Al的存在的温度ö ₂ ö ₃系催化剂进行了研究。结果发现，在〜735 K的复合温度下，在含有Mg，Ni，Co和Fe的催化剂存在下，N ₂ O的分解度不超过〜25％，且气流与5–6 s。结果表明，Al ₂ O ₃ –2RuO ₂ –400复合材料可在738–753 K的温度和7–15 s的接触时间下使气流中的N ₂ O几乎完全分解。
