摘要
研究了催化裂化再生条件下铂助燃剂上ＣＯ氧化反应动力学。在排除了反应管及稀释剂的催化氧化作用后，测定了铂含量为１０－６ｇ／ｇ的国产新助燃剂上的反应动力学数据，得出了在氧过量时一氧化碳和氧的反应级数分别为１和０．５。给出了６６０℃下的反应速度常数值及其置信区间。
The kinetics of CO oxidation over new Pt/Al 2O 3 promoter is studied under the condition of regeneration of catalytic cracking. After eliminating the catalytic oxidation of reaction tube and diluent,the kinetics data are determined over the new promoter diluted to 10 -6 g/g.The reaction orders of carbon monoxide and oxygen are 1 and 0.5 when the oxygen is excessive.The reaction rate constant and its confidence region at 660℃ are also given herein.
