反应气中氧存在可以降低炭黑- NO起始反应温度。

The presence of the feed gas reduces the initial reaction temperature of soot reaction with NO.

提高起始反应温度使催化剂床层温度整体过高导致飞温。

Initial temperature of catalyst bed is wholly too high.

youdao

炭黑质量浓度越大，NO的脱除率越大，起始反应温度越低；

The more soot concentration results in better rate of NO reduction and lower initial reaction temperature.
