Thirdly, re-oxidation rate equation was deduced and identified. The results show that the re-oxidation process of the catalyst obeys the contracted core model controlled by phase border, and the rate-controlling step is chemical reaction.
第三，导出了VPO-1催化剂再氧化速率方程并用实验进行了判识，结果表明，氧化再生过程遵循相边界反应控制的收缩核模型，北京化工大学硕士学位论文催化剂体相晶格氧扩散速率相对较快，对反应速率影响较小。
