采用程序升温脱附法(TPD)和程序升温还原法(TPR)研究了顺酐加氢催化剂XYF-5上的H_2脱附和还原反应动力学。结果表明,XYF-5对H_2显示有不同能量特征的两个活泼部位(Ⅰ)、(Ⅱ),对H_2的吸附为分解二位吸附,催化剂XYF-5的还原遵从速率方程式(6)。
The kinetics of H2 desorption and reduction on maleic anhydride hydrogenation catalyst XYF-5 was studied by temperature programmed desorption (TPD) and temperature programmed reduction (TPR). The results show that XYF-5 shows two active sites (Ⅰ, Ⅱ) with different energy characteristics for H_2. The adsorption of H_2 on XYF-5 is decomposition two-position adsorption and the reduction of catalyst XYF-5 complies with the rate equation (6).
