| Abstract: | Kinetics of reaction and catalyst deactivation were determined based on the dehydrogenation of C10 ? C13 heavy paraffins to the corresponding mono-olefins, and Powell method was used to optimize the parameters. Activation energy and pre-exponential factor presented linear relationship with carbon number. The results showed that dehydrogenation became easier with the increase of carbon number of heavy paraffin and the deactivation of catalyst became slower with the increase of LHSV and pressure. The validation of kinetic model showed it was in good accordance with experimental data. |
