在氧大大过量的条件下,考察了甲苯、丙酮在Pt/NM催化剂上深度氧化反应的宏观动力学.结果表明:有机物类型不同,反应的动力学特征也不同,其反应速率方程为r_(c7H8)=1.26×10~7[exp(-92600/RT)]C_(c7H8)/(1+bC_(c7H8))r_(c_3H_6O)=4.91×10~4[exp(-93300/RT)]C_(c_3H_6O)
The macroscopic kinetics of deep oxidation of toluene and acetone on Pt / NM catalyst were investigated under a large excess of oxygen.The results showed that the kinetic characteristics of the reaction varied with different organic species and the reaction rate equation was r_ (c7H8 ) = 1.26 × 10 -7 [exp (-92600 / RT)] C_ (c7H8) / (1 + bC_ (c7H8)) r_ (c_3H_6O) = 4.91 × 10 ~ 4 [exp (-93300 / RT)] C_ c_3H_6O)
