文摘
- •
Kinetics for Beckmann rearrangement of cyclohexanone oxime over silicalite-1 was studied.
- •
A special reactor was designed to obtain uniform reactants and sustain reaction temperature.
- •
Dependence of deactivation rate on weight hourly space velocity was investigated.
- •
The kinetics was studied by combining the differential and the integral methods.
- •
Reaction mechanism was determined with the assistance of in situ FT-IR and poisoning experiments.
