Kinetic Study of the Dehydrogenation of Isobutane over V-K-O /ZSM5 Catalyst

Article Preview

Abstract:

The reaction kinetics of the dehydrogenation of isobutane over V-K-O /ZSM5 catalyst was investigated. The powerfunction model was established;The isobutane dehydrogenation reaction tests were carried out between 833-863K and reaction pressure to atmospheric pressure by changing the contact time(w/F=0.464-0.532gh/mol) ,through the experimental data the kinetics of model parameters were analyzed.The results show that the power-function kinetic model is reasonable,the apparent activation energy is 177.7492KJ/mol.
