摘　　要：采用间歇反应器,对液相环己酮氨肟化过程中TS-1分子筛的催化活性变化规律进行了考察,在失活原因分析的基础上建立失活动力学模型:rde=1.01×1014exp(-1.17R×T105)C0A.76C0B.82C0C.38a1.64,并对模型参数进行估值。The catalytic activity of TS-1 catalyst for ammoximation of cyclohexanone to cyclohexanone oxime was investigated in a batch reactor. The deactivation kinetic model of TS-1 catalyst for ammoximation was established on the bases of deactivation scheme analysis. Statistics analysis results showed that the deactivation kinetic model exhibited a stronger capacity for experimental data and a higher reliability. The model is rde=1.01×10^14exp（-1.17×10^5/RT）CA^0.76CB^0.82CC^0.38a^1.64.
